glow plugs

[thomson]

My Perentie with glass fuses does not seem to be getting power to the glow plugs .I cannot read the wiring dia .Does anybody know where the plugs get their power from and what colour the wiring is and if there is a relay involved . thanks Peter .

Directly from the ignition switch. There is no fuse.

.. which also begs the question why are you needing glow plugs? Above the snow line I can understand, but in normal practice they start fine without them...

down to minus 4 and I didnt need them.

So near as I've been able to work out they mostly seem to be fitted for 2 reasons.

1. hey this is cool, everyone else has them why dont we put some in?
2. to fill the hole that you use to do a compression test.


(ok so they help if you have a lazy battery or starter and in extreme cold (-10 or lower))

I have never needed them before but at 5 am at Orange friday morning for the 1st time it would not fire up cleanly there was deep frost everywhere , when i put a meter on the plugs there was no power going to them , when it did fire up there was a dense fog coming out of the exhaust till it started to run cleanly .

If I gave it a couple of hand pumps it would start fine . So for 200 bucks I had the lift pump reconditioned , cut seats new springs valves etc and we are back to starting fine again. Glad it did it on the last day of152988152987152988 a 9000 k 2 month trip
