Testing alternator
Jimbo550:
I've gone through all the connections and everything seems in very good condition. I've taken the stator to a specialist who has looked at it and put a meter on it and he thinks there is nothing wrong with the stator at all. Where can I go from here and what should I test next?
ka-ja:
Hi,
It is a good chance that if the alternating coils are OK, the culprit could be the regulator working incorrectly, as previously stated, if the voltage to the exciter (inner) coil isn't correct, the ac output will be wrong, the only other thing that effects the output is the rectifier, but this only changes ac current into dc for the system and usually works or doesn't-no inbetween, the regulator is prime suspect, but hard to test correctly without the right gear, do you know anyone who can lend you one for a trial-Ken
PS If you haven't got the test methods for testing out PM me

I took the whole casing with inner coil (Magnetic bit) and ouuter ac coils to a guy who rewinds these things for a living so sure knows more then me. He put an ohm meter all over it and said all the figures came back as what he would expect and there was no problem with it. I have put it back together and still have only 11.5 v max at 4000rpm. i've tried getting some readings in ac from the three yellow wires but not with much success but i may be doing this wrong. Can someone point me in the right direction to test the ac output correctly?
i'm also thinking i should check the dc supply to the inner coil(magnetic bit)?
Thanks for your help.

I think I,ve sorted it!! Turns out to be the rectifier. Bolted a new one on and getting over 14v going into the battery which is better than what I had previously. Thanks or all the advice given:-))

OK now make sure all the green earth leads make good contact along with the big one from the battery to the LH rear motor mount
