Htmlkid Posted January 19 Report Posted January 19 Stupid question but does anyone know if the voltage regulator is tied into the engine monitor??? and if not... there are 4 cables going into the voltage regulator... what do that supply? Its in a 1988 M20J
PT20J Posted January 19 Report Posted January 19 The engine monitor does not connect to the VR. The schematic in volume 2 of the Service Manual will detail the connections. There should be power, over voltage indication, field, remote sense, and ground. 1
