Charge rate only 13.1-13.2 volts at the battery, both at idle and higher revs, with or without lights HRW aircon etc on.
Tomorrow I'm going to check for earth cable and other cable/connection problems, but if it turns out that the reg is defective, has anyone ever managed to replace the regulator with the alternator still in situ? Looks like it would just be possible with my slim hands. The alternator is around 3 years old and IMHO should be ok regarding windings, commutator etc.
TIA
