Alternator low voltage

[M250cnc]

Definetly a Vectra-C at that age.

Hi left it for 24hrs measured the battery voltage and it was 12.5v so it is working correctly "not draining" albeit lowish output voltage

If it does turn out to be the diodes, and for some reason you can't replace them then you can allways turn it into a pretty powerful and fast brushless motor.

Jonathan you seem to be obsessed with motors. :lol:

Thanks Phil
