Build complete BJ45 rebuild start next week in Bolivia

And this:

I cannot test, because I have the 11 volt plugs in just to cap the holes and I don't dare to connect them. And so I haven't connected a bus bar I don't hear the no. 1 Glow Plug Relay click and I don't measure any voltage from either the Glow Plug Resistor nor the lead to the bus bar.

So I can't check there if I don't have the original plugs which will come soon I hope?

On the Pre-Heater timer side, what can I check there if the bus bar isn't connected?

Hmmm my manual shows this:

And so I tested this, and there is continuity between the terminals.

Now if I test it like this:

Then I there is no continuity.

So both tests appear to turn out okay. Does this mean the resistor is okay?

Ha ha. Million dollar question! But I doubt it Coen. (I think it just means that failing either of these tests would have confirmed it was a dud .... which is quite different of course.)

I see your problem.

You've no doubt already decided this but .... Can I suggest trying to order two complete sets of plugs and be sure to monitor the busbar voltage when you test things with them fitted/connected. (So you can stop immediately if you see 24V being applied for any more than 6 seconds for instance!)

Meanwhile I'd run with the 11V plugs disabled in some way (as you have no doubt also already decided to do).

How long have you got before the weather gets cold enough to require the plugs?

I'm wondering the same thing. But I'm no electronics whizz kid by any stretch of the imagination.

If I was you I think I'd be resigned to waiting for my new plugs so I can put the glow circuitry through its paces with everything connected and while closely monitoring the voltages and voltage durations at the glowplug busbar. (ie. Put the timer in the "too hard basket" for the time being.)

Thanks all, I have to move from where we are now and I don't know where we end up and if I get internet connection?

Okay, another question:

I have transformed [soldered with bronze] the blown up glowplugs and I want to install them again in the engine.

Now I want to know if I can do the voltage tests on the bus bar with the 2 not glowing plugs?

....Now I want to know if I can do the voltage tests on the bus bar with the 2 not glowing plugs? ...Coen

In my opinion ....No ....because I think your readings would be "up the poo" Coen.

While you don't have a "glow controller" in your superglow circuitry, you do have a "glow plug resistor" (for your after-glow phase) that I believe works in a similar way. (That is - It has resistance and heats up to drop the voltage to the busbar.)

So I think the same thing applies as with a "glow controller" in a manual glow setup. That is ...Reduced current flow (from 2 missing plugs) means reduced voltage drop (through the resistor) which means excessive voltage being applied to the remaining 2 working plugs (which occurs during "after-glow" in your case).

In other words ...without the correct current-draw (from four correct working plugs) I believe your resistor wouldn't drop your voltage properly for your afterglow. So I think you'd see your busbar being fed with high voltage for too long (whereas with four correct working plugs I don't think this could occur).



PS. So I would suggest disabling your glow system until you can install four correct plugs. (Because having it connected up with just 2 working plugs risks exploding those remaining plugs too.)

I am way ahead of you on that and I was never wanting to drive with only 2 working plugs, but only maybe to test. The bus bar is waiting just like me on the four new plugs....

Oops the relais wan't clicking because I had still the Pre-Heater timer not connected... But I will find a decent spot to work on the cruiser some more in a few months. Probably in Suriname. I have started to believe something must have fallen into the engine, because I hear a faint rattle like I'm driving a VW beetle, but only very faint. Must do a compression test to be sure? No time, or place to take grand mesures now....

Zipping caipirinhas on Brazilian beaches as we head north to French Guyana...


Okay, I have connected the Pre-Heater timer connection again, and I hear the first relais click again. I measure voltage at the connector that goes to the bus bar: 24 volt for about 5 to 6 seconds, after that 8.9 volts for 10 seconds [I did not time these with a watch, so might not be very precise] after that it drops to zero. So I guess all is well.
Then my thoughts go back as to why the glowplugs have exploded? Can a dirty bus bar [and incorrect conduct] have lead to building up less volt in one and more volt on others?

I'm not personally familiar with "superglow" but this follows the pattern I'd expect to see Coen (based on what I've read/heard).

Yes. I believe this is entirely possible Coen.

If any plug(s) is/are open-circuited or not making proper contact with the busbar, then I believe the remaining plugs will get hit with more voltage (than they should receive) during that "second phase" (where you recorded 8.9V).

I think everything works fine now. After the pre heating (#2) relais did its job, the #1 relais takes over during starting with the full 24 volts for 5 to 6 seconds. During this time the engine should start and should get an afterglow of around 9 volts for 10 seconds, which is the time the cilinders need to warm up in a very cold environment. After this time has elapsed the timer switches of. So far so good.

Now the question is: what caused the burn out of the glow plugs? They don't burn out after 10 second or half a minute of glowing. They can only burn out when they are glowing a long time (hours) in combination with oxygen. Somewhere you wrote that there was voltage on the busbar while the engine was running. That brings me to the idea that there was a problem with the timer or the #1 relais. Or the timer didn't swtich of in time or the relais was stuck in the closed position.

Having been in the electric and electronics repair bussiness for many years I have expierenced that sometimes a problem spontaneously disappears and seems to be a one time occurence.

Maybe it's wise to connect a little light bulb to the bus bar which you can monitor on the dash to make sure that it's not happening again.

That might be a nice idea!

Okay, on with reality:


cutting the sticky stuff. Mangos are not a pain, but the jackfruit is.

My new friend Pedro brings us fresh coconuts.

happy to be on the road again...

A very rare 4 door Bandeirante. I heard people say that Toyota Brazil produced a very limited edition of 4 door Bandeirante versions?

This is the work of Jesse, one of the best 'limusine' builders of Brejo da Madre de Deus.

Then we spot a 6 door version. Those are really rare. We have been lucky to pose together.

I hope you all appreciate these?

I most certainly do. My wife started drooling at the mention of Mangoes, and I drool at your troopy and those Bandi's!

Very, very cool.

Your posts are always the highlight of my day. Had jackfruit for the first time last year. Maybe you've also had zapotes, sapodillas, caimitos or guanabana? Best part about central/south america are the fruits and landcruisers

Oh my god.....

Almost looks like the Jeepneys here in the Philippines lol!

 

[twoyotas]

always looking forward to your photos. love the shot with the mangoes and jackfruit on the hood! takes me to a better place.

i look at the first few pics and go "holy crap you have your work cut out for you"
then i jump to the last page and see the result "WOW!!"

now to read the rest of the pages ...

i love that 4 door on this post 415, how much and where is it?

They are around 9.000 U$, if you bring your own chassis, or old Land Cruiser. If you don't bring a model to be remodeled the price depends on the year model you want it to be. A 1990 model Bandeirante modified will cost you about 25.000 U$ as a 2000 model would be around 36.000 U$.

You google: brejo madre de deus bandeirante

Good luck

I thought I might post some more Brasil here just before we enter French Guiana in a few days...


Four little lizards playing on the rocks while we look for the oldest rock paintings in the America's.

This giant ant is one that you wont forget easily when it stings you... Better not give it any reason.

Ready for the Adventure.

"Adventure" framed.

Brazilians love sound in their cars, even if that means a little less space to pack groceries.

Then this lovely lady appears in her little truck.

Evenings on route are well spend at some fuel stations catering especially to truckers. Free showers, wifi, free coffee, good restaurant, shade and dry parking.

River houses along the Amazone river.

Small us among huge Brazilian trucks on the ferry across the amazon. 40 hours.

And then we got really stuck on the equator. Right at the middle of the earth.
