So I last night I decide I have a chance to get away for the day. While I'm packing up my warm camo stuff, coyote calls and an assortment of weapons..... Mountain Matt (my 6 year old son) sees me and starts the begging process to go with. No sooner do I decide to let him come than his little brother (age 3) starts begging to come. So we gather up more camo and make some plans.

I decided to head toward Baker NV and go north. Make a few stops along the way to see if any coyote has a suicide wish. etc etc

So I wake up a little after 5 and wake the boys up. I swear they were more excited for this than Christmas. We get dressed load up my 1984 BJ70 and headed out.

About 10 miles out of town we see our first wildlife. A heard of Elk are right on the road. Both boys see them which makes it nice. The little one was a little sad that we didn't get to shoot one.

Around Baker NV we head north. At our first stand, the coyotes are all around and howling like mad. I called pretty good and I'm pretty sure I could have got one to come in, but everytime they answered me, the boys would get a little excited and very wiggly. I'm sure we were busted early, but it was fun. Next stand same thing. Next time I get in the rig both of my hunting partners fall asleep so I decide to drive until they get up. By the time they wake up we are by Ibapa UT. I start heading back toward Ely when I get the first request for a lunch break. We stop and I break out a genuine US Army MRE. The boys love that stuff. While stopped I added 10 gal of diesel. We hit the road again.

I come to a cut off that shows where the original Pony Express trail cut through over what the map says is the Antelope Range west of Tippett... and I decided to take it. We went about 15 minutes up this canyon, and thats where everything started to turn into an "adventure".

The snow was getting deeper and the canyon more narrow and steep. Pretty soon I'm stuck and using the winch. No big deal. The only reason I used the winch was I was sliding off the road and didn't want to roll down an exposed drop off. The winch was more of a safety thing. Not much longer than that I was going up a steep area, going in 1st gear in 4L, having to use the steering back and forth to help with finding traction. I'm not making much progress, but I am making progress when "it" happens.

The pretty purr of the diesel just stops. I'm about 200 yards from the top of this pass that claims to be the highest point of the Pony Express trail. I also have to cross Spring Valley and another mountain pass before I get to Schelbourne and HWY 93 and something resembling cell coverage.

Wall-e (my BJ 70) won't run. I start thinking about options. I sent my first SPOT message that says I'm "OK" just in case they need a starting point to find my body in a few days . Next I hike to the top of the pass with my HT ham radio to see if I can hit a repeater near my home town. No good. I also check for any cell coverage. Nada.

So I go back hoping that a little cool down period will help the beast. Nope. I start going through a systems check. Air, spark, compression, fuel... right? I check the air filter to make sure nothing is blocking that. Nope. Then check that all the spark plugs are.. well there aren't any spark plugs so spark isn't the issue. I don't see a hole or piston so I assume that the rig is still getting compression. So that leaves us with a fuel issue.

The rig will start and idle for 1-2 seconds then it just dies. I pull the fuel filter to see if anything obvious is clogging that. Seems OK. So I pull out the manuel and start reading. I come across a fuel shut off valve that is supposed to be used in case you turn off the rig and it still runs. I play with this valve and notice it is in the closed position. I have Mountain Matt crank it over a few times and notice that the valve opens when the starter motor is engaged. I then hold the valve open and my son cranks it and it stays on!!!! I rig the valve with a tie-down strap to stay a little open and it starts again. So I figure its running go with it. I jump in and fight my way to the top of the pass. Its still running so I start toward HWY 93. The only thing that seems different is not as much power. I finale get to the Highway. I pop the hood again and take my temp fix off and see if it runs. It won't so I rig it up again and make my way home.

I made it home and put him back in the garage. I came in and collapsed. I'm beat. After eating some dinner, I went back to the garage. I take my temp fix off and try it again. Nothing. I then decide to check the fuses. On the way home the only thing electrical that would work is the radio and headlights. No blower for the heater and no dash gauges. I pulled all the fuses and found one called "engine" that was a 15 amp that was blown. I replaced it and it is running like a champ.

Anyone want to claim to be either a diesel mechanic or a CSI specializing in Landcruisers wanna inform me what I did to cause this problem? The only thing I can figure is it over-heated going up that last hill and blew the fuse. What dies that fuse run?

Any other theories are welcome.

I'll throw up a pic of our lunch stop. I don't know why the pic tuned out so small but........

Nice little story. I bet the kids love the landcruiser:D

I doubt you did anything to cause the fuse to blow. Unless it blows again in the near future,I wouldn't worry.
The fuel shut off valve is the primary way to shut a diesel down. The thing that cuts off the air is for a smoother shutdown.
The fuel is turned off/on via the EDIC system and I guess you found the fuse.
There is also a low oil sensor that will also shut down these engines by turning the fuel off
 
Good read, thanks for sharing it. I need to lodge that in the memory bank in case of similar situation in my 87 BJ70. You must have been sphinctering having your young kids to worry about.

I passed my General so I could carry an HF radio in the 70 along with the 60 watt Yaesu 2m. Definitely makes the solo BFE jaunts more relaxing. Did the Spot transmission get rec'd? I've read good and bad on those. Occasionally Cabelas in Reno gives them away free as long as you sign up for 24 month subscription.

If you're ever in South Tahoe let me know. About the only time I get to Ely is on my way to Moab. One time my tow rig broke down there and we spent a couple nights. Saw a movie in that fantastic 1920's theater and were the only people in there. That was a few years ago and that huge mine was closed and the town looked like it was terminal. How is it now?
 
Whats a EDIC system? electronic diesel injection center... just guessing.

I wasn't that nervous except for the kids. We had warm clothes, another round of MREs to go and stuff to make a fire. I just knew I would be more comfortable at home :)

The SPOT worked fine. I only used the OK button so a posse wasn't being formed back in town. The only time It hasn't worked for me is when I didn't let the unit "see" the sky. Using it in the house or on the inside of a car doesn't seem to work.

Upgrading to a General class means I have to buy more equipment and yada yada yada. I'm sure its in my future.

As far as how is Ely going.. Gold prices are nice and the mine is doing well. The theater is still from the 1920's and full of charm.

Last time I went to Reno was for the Rubicon :)

)

Its too old to be electronic;),I forget the meaning, but your not far off.
It can be disconnected and operated via cables like some of the older B engines.
It has 3 positions,start,run and stop
 
I went out and looked..... is the EDIC have a little arm that goes to the fuel shut off valve? Does the EDIC get input from both the low oil indicator and __________????? Is it temperature controlled as well? When I first popped the hood it was pretty toasty under there from the long climb up a snowy hill and not much air being forced in the front of the vehicle with the slow speeds....

If it is temp controlled, does it blow the fuse or re-fire after it cools

Thanks for helping my non-mechanic self figure this out.
 
wow cool story total opposite of our climate - snow whats that - we get SNOWWASH option at the car wash thats the closest we get to SNOW.

Funny you should mention that... I took it for a little drive today and was watching the temp gauge like a hawk. The only time it got to full operating temp was climbing a grade and on the gas heavy. Going down hill it cools way down. I suppose where your at it goes to operating temperature pretty quick and stays there. When I start it in the morning I have to use the manual glow plug switch and do at least a 10 count before it will fire.

Cheers...
 
ummm, "full operating temp' where exactly is the needle sitting when you say this?
edic is controlled by a computor and the comp senses key input and oil level input.
what is the level of oil?
in the future, fire the truck up and disconnect the edic arm. this will prevent the engine from stalling BUT it also means you have to stall the truck to shut it down. the controller could be on its way out or the edic itself or the oil could be too low.

Rosco, his is a 85 and if it is an ex Cnd model then it will have the edic, ours had them till at least 87
 
Nice adventure i bet the kids loved it ,i used to love going shooting with my old man in his 45 series cruisers,
As for your fuel and shut of issue a mate had/still has the problem with his 85 hj75 troopy ,it wouldnt turn off one day by the key and another mate rambled something about a solinoid or something and now it has to be staled to turn it off ,do the hj's have the same gear as the bjs? for this issue
 
full operating temperature seems to be when the temp gauge is horizontal. that is its pointing to the 9'o clock position.

Another thing I noticed was the amp meter is pointing way up the the "16v" ??? dunno whats up with that.

I guess I've broke it and its time to sell dirt cheap.......................... not

Im not disagreeing,merely saying that it could be disconnected and run from cables like old school diesels.
I dont know why they ever bothered with EDICs in the 1st place

The EDIC is not controlled by heat sensors.

If your gauge is accurate,thats not really overheating,both of mine sit around 7.30-8.30ish.

The voltage gauge should sit around the 14v mark. You might have a dying regulator,Im not sure if this could blow the engine fuse,but its worth checking.

I had an issue like this when driving north once, ended up being some trailer light wiring under the rear carpet that needed sorting out... big heavy cooler on it, made it ground out somewhere...

I would just open the hood and shut it down by manually pushing the injection pump lever that the EDIC actuates...

Get rid of the low oil pressure shut down BS get a manual gauge, wait for it to register pressure before reving or moving the truck in cold conditions... Never an issue since...

cheers
 
Well I'm back :-(

After work tonight I did my usual run a few errands before I get home. While stopped in talking with a local shop owner, I left the 70 on. As I was visiting I could hear the purr of the diesel just happy to be alive. Then all of the sudden It stopped. I told the shop owner cheers and went out to check the rig. It wasn't running anymore and it was just sitting there with the radio and lights on.

I jumped in and tried to start it. It would start and idle for 1-2 seconds then die. I'm thinking I'm a genius and I've been here before so i pop the fuse panel and sure enough the "engine" fuse is blown. I replace it and attempt to start it and it blows the fuse again.

I'm thinking I can by pass the fuel shut off valve with my handy ratchet strap and drive the 10 blocks to home. After I get it home I'll post up here and figure out what the next step is.

Then "IT" happens.

I smell smoke.

Not the nice smell of a white Christmas fire burning in the fireplace heating half the town... its electrical smoke. I immediately shut off the key, but since my by-pass is in place, the engine keeps running. I scramble out and pop the hood and take the strap off the fuel shut off valve and the engine kills.

I then look inside to see where the smoke is coming from. It was mostly coming from the right side of the vehicle inside the cab. almost like its coming up between the windscreen and the dash. I also noticed some traces of smoke coming out of the vents on the dash that point to the passenger area.

I also looked under the hood and noticed some remnants of smoke coming from a conduit that exits on the right wheel well below the battery.

So next i take a look at the fuse box wondering if all this juice is flowing... why didn't I just blow a fuse? Well the "new" fuse was melted. Not just blow, it was a melted blob.

Made a call and towed it home.

I start poking around now that I'm in the garage and have some light and warmth. I disconnected both batteries and started looking

The "engine" fuse - I tried to take it out with some pliers, but it was melted. After 5-10 minutes of careful teasing I got the fuse out.

I don't know what I've done to this thing, but it isn't pretty.
 
Wall-e not healthy, now stinky and dead-e(h)

at least now you can trace the culprit although you probably have more parts to fix...

maybe there is a leason for all here, if the main fuse blows find the problem before the insurance company has a claim... me, i probably would have let it burn, collect the $$$ and buy a different truck. depending of course on the coverage i had.
 
Ouch. Good thing that happened in town and not out in BFE. I wish I had some pointers but I'm just tagging along trying to learn something. Please keep us posted.
 
Spent a couple of hours in the garage tonight. I think I have a couple of answers and several more questions.

I started under the right dash. I just took things off looking for something toasted. Everything under the dash looks fine. I see no evidence of anything that appears to be burned.

Under the left side, thats the drivers side to me, The only thing unusual is the fuse box. The fuse that holds the fuse for "engine" has some damage. from the fuse not blowing but melting instead.

questions:

I'm still not sure what the "engine" fuse goes to. What does that do? Alternator? Voltage regulator?

I started poking around under the hood/bonnet. Nothing looks out of the ordinary. I'm am confused by what is coming out of the back of the alternator. Anyone have any ideas what all those hoses are?

Anyone have a wiring diagram that can tell me what that "engine" fuse does?

I'm lost :-(
