I continue to uncover the odd weakness in the car after pressing it into daily service.
Charging system failure last night - AMP light on brightly and I observed the battery voltage dropping with a multimeter when the car was running. All the contacts were inspected, cleaned and protected with dialectric grease by myself and the fuses are fine.
The car appears to have an orgiinal style alternator and seperate metal regulator box. This is mounted next to a modern plastic relay (presumably for the supplementary electric cooling fan or the hazards) and another standard looking metal box - the headlight relay I believe.
I wonder if there is an easy way for a simpleton with a multimeter such as myself to identify whether the alternator or regulator is at fault?
