The original alternator no charge light works by a voltage difference between a separate alternator terminal & 12v at the battery. When the alternator terminal is at 12v the light goes out.
I have connected the lead from the separate alternator terminal to the relevant wire on the dash 2 but the light does not go out.
Can anyone suggest what I need to fix this? I've included a wiring diagram below.
