What voltage is the glow plugs circuit? I checked them and only got 9 volts. When starting how does the glow system work, I turn the key and it doesn't glow until just before start. Not at on position like my Defender is, that correct?

They are straight off the start switch according to the wiring diagram. The 4 plugs are in parallel with a bus bar across them, so all get 12v.Quote:

I'm not 100% sure how they work in terms of turning them on. Is there a half position between engine run and crank that you can hold the key at?
300tdi's had a temperature sensitive glow plug timer, so much more advanced than the Isuzu. I'm sure later engines will also be smart control.
The the Isuzu doesn't need glowing anyway unless it gets REALLY cold. Mine have never been connected.

Thanks steveG. You are correct that's how I was checking them. Just didn't expect to see that kind of voltage drop. That is how I worked out the glow switch worked just different to Defender so checking. Thanks for the clarification.
Matt.
It's a peice of crap that is only going to cost you money and cause you grief. But being the wonderful human being I am, ill come take it away for you.
:D
Ha ha sure you will Serg. Turns out there are a few thoughtful people willing to "help" me out of my situation.
