A minor irritation, is that the ignition light on the Perkins console has stopped working. Obviously checked the bulb, which is showing a resistance, and when the ignition circuit is on I am getting 1.7 volts rather than 12.
Alternator is charging OK, so no worries there. Perkins manual only covers the alternators and the starter motor, and does not publish a working circuit diagram..
Anybody got one please?
