ive never had it wet since ive owned it,now 2yrs,but i did buy it off a indian guy that seemed a bit cagey here and there.
should i whip the thing open and check contacts and such?

ok,i pulled the it out and opened it,there was a little bit of oxidization on one of the two little black processors (i think thats what they are?)
I cleaned it best i could with a small screwy and biffed it back in,the tacho still reads 2500 and rising on idle,i noticed when the key is on and the engine is not running the tacho needle jumps and sits just off the resting pin it sits on when not running,if that makes any sense.

forgot to mention,its an intermittant problem,sometimes it does it on startup,then i notice when drivint its back to normal.

Ok looking at the controller it appears to be like the earlier td42 one just 24 volt.
The double glow relay is a bit confusing can you take off the air box or get the camera in and take a shot of the rest of the glow plugs and how they connect up.
they all connect up the same way from what i saw when i removed the bar yesterday

That 5 volts is good, that means that stage 2 of the glow plugs is now working.
You may of had a bad connection at the temp. sender or one of the relays, double check terminals for corrosion and clean if necessary.
Then I would try another cold start with the voltmeter connected to the glow plugs and placed so you can see it when sitting in the vehicle.
The glow plug warning light in the dash does not reflect the whole time the glow plugs are on. This is what should happen
1. Turn the ignition on, glow plug warning light will come on for 2-6 seconds (depends on engine temperature).
2. Your voltmeter should show 12 volts for up to 15 seconds, even if the warning light is off in the dash.
3. After 15 seconds stage 2 should kick in, your voltmeter should be reading around 5-6 volts.
4. If you start the vehicle the voltmeter should keep reading 5-6 volts for a period of time or until engine reaches a certain temp.
I see the ECU is 24 volts, I guessing that someone at some stage has fitted 12 volt glow plugs.
Hi rodney.
Ok,i done as you said,and the strange thing is,I used the neg probe on a few earth points,and the readings were crazy.I earthed off the batt and got 5vlts or so,then earthed on the intake manifold and got 17v,then earthed it to the block again and got the same,17vlts?
I also let it run for 10mins and the voltage didnt chage at all,stayed at 17v?

There is either something strange going on with your vehicles electrics or your multimeter.
I think you may need to take it to someone who can look at it for you, if you still have cold start issues.
I downloaded the Russian workshop manual from this forum and it has the closest matching wiring diagram that I can find to what you have told me about your vehicle.
I can't understand a written word but the pictures look good. I guess I can't say I got it for the articles then lol
