Htmlkid Posted January 19, 2025 Report Posted January 19, 2025 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, 2025 Report Posted January 19, 2025 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
