As far as I know the green tops were a JDM only modification. They were 6v plugs that heated up really quickly when hit with 12 volts - for the impatient Japanese market? That is also why it is not recommended that you extend the time these plugs get power - they go from hot to burnt real fast.

Be careful where you buy them - get OEM parts if possible. Too many problems with the knock-offs/3d party plugs. I bought mine in Japan with Mitsu numbers on 'em.

Mitsubishi used 3 different "start systems" on Pajero's.
And the glow plugs are different.
1. 12/6.2 V.
2.11 V.
3.12 V
Probably you have the 1 system. It should produce 12V for 4 sec(to start) and continue supply 6.2 V ( to support started engine) There are 2 rellay (you should hear them clicking)

I bought it with 2 batteries and they came wired up that way...whatever, it works great for me. and yea I know I can get the manual knob for high idle but I am still pissed off I don't have the factory one. like what reason does somebody have to take that out of the truck???

I cranked last winter but this winter I have done the following.. Turn key, wait for glow relays to turn off, turn off key for 10 seconds, turn on again, wait for glow plug relays to turn off, turn off key again for 10 seconde etc etc.. Maybe one cycle for every 3 deg below zero. It was only -9 here this morning (Balmy sunny sothern Ontario) but she fired up fine after 4 of these on/off cycles. If you just turn from on to acc and back again the glow plug relays only click over for one or 2 seconds. You have to right back to off to get another 7 second glow cycle. Either the controll circuit resets with an off on the key or the 10 seconds with the key off allows some heat from the plug to sink to the heads. I am assuming it is the latter as the start up is much smoother than a crank only start.

Has anyone taken a glow plug to the fuso dealership to see if they could find one here in Canada? I know the 2.8l TBD used in the smaller Fuso's is the same engine as used in the newer Paj's. I also know that the tranny in the Fuso might fit with a small body lift. But back on subject, if the 2.8 PN for the glowplug is the same then we can get plugs here in North America without getting hammered for shipping from Japan.

The problem at -30 is that it takes the engine 15-20 seconds to get a fast enough spin going to fire. Once it's spinning I back off, wait for 5 seconds, then cycle and spin again. That's when she fires up.

I've checked everywhere. The best - let me rephrase - the ONLY ones I could find were from Mitsubishi to the tune of $42.00 each. I ended up buying some NGK plugs that work but are 11v not 6.2v.

Did you bypass the ballast resistor then to get the full 11V to the new plugs?

Nope. I just took out the greentops and put in the NGK's. I thought about doing that but I didn't feel too comfortable doubling the voltage to the plugs for an extended period. In theory it should be fine but.... Anyway, I'm still hunting for the Greentops. The NGK plugs were $7.00 each plus $10.00 shipping from the states. So for less than the price of one Greentop from Mits I have 4 NGK's that work. Albeit not stellar, but functional.

We're getting pretty deep in the thread here and perhaps this should be a new topic but this goes back to my earlier post about not feeling right bypassing the resistor in the glow plug relay circuit.

Can someone explain to me the difference between an 11v Glow plug and a 6.2v glow plug? The way I see it is they are both just resistance heaters and in each one the heat generated is in direct proportion to the amount of juice introduced. I suppose it's possible that one, having perhaps a smaller filiment or less mass, will heat up faster, but I would suspect that after the first second or two they would be giving off relatively the same amount of heat. This might explain the "Fast start" nickname attached to the 6.2v plugs as they may get there faster if they are designed with a smaller filiment. But it would follow that during the second part of the cycle, once the truck is running, 6v to either plug would be exactly the same amount of heat, as the plugs are already hot.

Am I out to lunch here?
