How can I check whether the alternator is working ok?
Pulled up outside the garage after a 12mile journey turned off engine , opened garage door, engine wouldn't restart - seemed to be low batt volts (dash lights all dimmed). Had battery on charge overnight, started immediately this evening.
The battery is 2 year old (and was changed because of similar symptoms of not holding a charge).
If it is the alternator at fault is it a garage job or can it be changed at home? Any websites or info you could point me too?
Also are the diodes housed within it or separately? thanks
