Picture of 3B Glow Plug Electrical Setup

[PVCruiser]

Hi All-
Pulled the head on my 3B ( it was cracked ), put a new OEM one on ( lots of money ) with stainless steel cups from OZ. Also installed a Turbo-Glide Turbo kit... I'm having trouble getting the rig to start... Did a search and read the past posts on troubleshooting, also have the FSM for the 3B motor.

I think I might have a problem with the electrical hookups for the glow plugs... ( As in I some how managed to screw it up )

Does anyone have the time to post pictures of the wiring where the glow plug wires hook to the post on the manifold. Also a few pics of the metals strips that carry the current from the post to the glow plugs would be appreciated.

I realize this is a major pain in the butt to take pics and post them on MUD. Any pics are greatly appreciated and I owe that person a 6 pack when I meet them in person.

Thanks for any and all help!!!!!!!

BTW, injectors are rebuilt and pump showed no signs of trouble before head was pulled. Also, I haven't adjusted the fuel screw yet....

Hello
Sounds more like you have air in the fuel system. Fill the fuel filter with fuel, crack loose the #1 fuel line at the injector and pump the fuel pump, until you see fuel coming out at #1 line, then try to start. You are in a warm climate, my 3B will start with no glow plugs at 35 F no problem, but runs rough until warm, also if you do not have the valves adjusted right it may not start either. After you get it started, and warmed up, readjust valves. waaz

Thanks Waaz, but I have already bleed the system ( I wish it was that easy)...

My rocker arms aren't adjusted properly as I haven't warmed the engine yet.

I know I have an electrical problem as a little puff of smoke comes up each time I turn on the glowplugs.

My next check will be return lines and assorted fuel lines ( for cracks)....

But I still need pics of the glowplug and wiring area on the manifold ( it's not that freaking complicated so I feel like a total idiot).

Thanks

Seth

Damn, left my camera at work and won't have it til tomorrow. I'll shoot some pics then if somebody already hasn't.

BTW where in Kali are you?

Far enough away from Humboldt not to get a contact high .












JK... actually I'm in Los Angeles, Redondo Beach.

I'll be up in Stockton for Georg's swapmeet in April. Will you be there?

A pic is appreciated.

Thanks

On both of my BJs 42s there is a red wire that runs to the + side of the drivers side battery that must be hooked up before the glowplug will work.

oh I just saw that you have a BJ70.

 

[cruiser_guy]

Seth, you'll need to specify if it is the "Superglow" system or not. They look a little different. If you're not sure what you have post up a picture and we'll know and then we can better help you.

 

[PVCruiser]

Okay.. I'll get back to you.

Here ya go... ( This is a before pic)... What I can't tell is if I have the stack of components correct on the manifold heater.

Thanks

Puff of smoke? Where is it coming from? The bus bar, or closer to the battery? If its near the battery, it means you may have a ground problem on the glow system and you blew out the fusible links.

 

[PVCruiser]

It's towards the back of the Motr, towards the firewall.. I've seen it a couple of times...

 

[dieselDaryl]

Okay, that might just be oil/diesle/cleeaner/whatever burning off the glow components when they heat up

Did you check for bad plugs? If you take the bus bar off, there should be continuity between the tip of the plug and block..

Did you run through the checks in the 3B manual under the glow section?

You could leave the glow system disconnected and try a little ether to see if it starts. THat will tell you if its a glow problem or something else. Use the ether very sparingly.

I would check the plugs. I fried a brand new set of plugs because someone had 'repaired' the current sensor incorrectly, therefor the 6V plugs were getting 12V for way too long and cooked them

 

[cruiser_guy]

If you take the bus bar off, there should be no continuity between the tip of the plug and block..

There SHOULD be continuity on the plugs. No continuity is a sign of a burnt plug. As dieselDaryl says though, you MUST take the buss bar off to check all plugs individually. Otherwise one good plug looks like all are good.

BTW that looks like a "Superglow" system to me. I'll shoot a picture of my '82 BJ60 which is a 12v Superglow but it SHOULD be similar.

 

[PVCruiser]

Thanks.. After I recharge the batteries, I was going to run all the electrical checks for the glowplugs in the FSM trouble shooting section. I'll let you know what I find on Friday ( can't work on Cruiser until Thursday night )

 

[cruiser_guy]

This is what the glow plug system looks like on the '82 BJ60.

 

[dieselDaryl]

There SHOULD be continuity on the plugs.

Duh sorry, yeah I know that, just wrote the wrong thing. Original post corrected..

 

[PVCruiser]

Thanks guys. I'll tinker with the 3B tomorrow night and try to figure out the problem

Puff of smoke huh? I had this problem too. It turned to be corrosion between the feed just before the bus bar. I took it apart and found that there was alot of corrosion. I filed it down, sanded it, and applied some electrolitic grease to all contact points.

Yo Seth, I will be in Santa Monica next weekend with my BJ42 in case you don't get this figured out and you want a real-time, real-life example of a 3B. But I'm 24v non super-glow...

Hey thanks for the offer!! Sadly I will be in Costa Rica next weekend. Leaving Thursday night coming back late Monday night, tuesday morning. If you are in town before or after April 13-17th I could use a little help (help!).


Update:

I know I've wired the vehicle properly. Any smoke I saw before was exhaust and/or my paranoia. I spent 20 minutes carefully looking over the glowplug starting system and eveything is wired properly.


At this point I think it's one of two things:

1) Either low oil pressure or 2) cracked return line for fuel.

Syptoms:

Engine is turning over very quickly and It almost runs on it's own. Every time I start it, I think it's going to start running, as it feels so close everytime. Exhaust fumes come out...

Plenty of fuel is getting to the injectors as I have cracked each one. Timing is not off on the pump, as it ran fine before I pulled the head. Injectors were just rebuilt by the top Diesel shop in the area and were also working fine. Battery was fine, with excellent charge. Could it be anything else?

Background:

Wanted to put a turbo on the BJ-70 as I need to sell it ( the vehicle/money pit). In the process of installing the turbo, I discovered previous owner has broken exhaust stud and left it in head ( thank you). Wanting to make sure my customer would get a quality unit, I wanted to fix stud.

Pulled head and it was cracked. Fast forward a lot of money ( and headaches). I had a new OEM head with precups from Geoff Walsh, and new turbo installed.

Current Situation:

Turbo oiling is taken from the same takeoff as the Alternator pump. Perhaps this new demand for oil has caused a drop in oil pressure ( causing me sensor to shut the engine down)?

Other option, the return line from the injectors going back to the injector pump is metal, perhaps that cracked? I already did a soapy water test of the other lines as they are easy to get to... This is the only line I haven't tested.


Next steps....

I'm going to pull the oil sender this afternoon. If the engine doesn't turn over, then I will assume it's that steel return line...

Have I missed anything? Coud it be anything else?

( If you've read this far, a big thank you!)
