Hi...got a Chevy LUV with a diesel engine, branded Isuzu.
Power to the glow plugs comes on for 1 second after turning on the ignition, then the power cuts out (measured at the input to the glow plug relay AND at the plugs themselves).
Where is the timer circuit located that powers the relay?
Is the circuit diagram for this anywhere on the 'net?
TIA,
Stan.
