Discovered tonight that when I switch on my hazard flashers the ignition comes on and a fan starts running. Slight pressure on the hazard switch switches the ignition and the fan off. The car is fitted with the Porsche aftermarket immobiliser which is adjacent to the hazard switch. When the ignition is on (but not the engine) the oil pressure gauge reads max. but previous threads suggest this is likely to be the sender. What is the earthing arrangement for the oil pressure gauge?
Thanks,
Don.
