Hello,
I have a 1984 2H HJ47 with the following problem. The voltage on the key switch at the ACC position reads the full battery voltage, however, whenever I switch to IG (ON) position, the voltage at the IG connection drops to around 5V. This results in many of the lights not working and the car being reluctant to start. The problem stops when I remove the engine fuse of the car, which results in the glow plug indicators not lighting up and the voltage at the IG connection (at the key switch) being the full battery voltage.
I know the connection from the engine fuse goes straight to the voltage regulator, is the voltage regulator faulty or is this a problem with the glow plug circuit. What should I test next to find out?
Would appreciate a response, Sam.
