Hi Guys,
Vehicle is an RB30 Patrol, carby model.
I've been trying to find out how to test the auto choke bimetal piece.
I performed following tests on it.
1)I applied +12V to blue wire and -12V to the end bit of the bimetal spring for few minutes.
No movement of the bimetal spring
2)I checked the continuity of the heater circuit with a multimeter.
It shows as open circuit. No resistance reading of any kind.
3)I checked the power to the blue wire from the socket at the vehicle end, there's no power to the blue wire, even when ignition on. I'm not sure whether the power to the blue wire is activated via a tachometric relay.
As the carby is out now, I can't test that(or may be I can by cranking the engine?!). But, somehow, I doubt the power to the auto choke is activated via a tachometric relay.
Any help/guide will be appreciated as I'm a fair bit lost atm.
Cheers
Dom
