Hi
Markrop...My fault on the coils was that one coils was showing a very low voltage.
If you have a voltmeter, and whilst you have the alternator disconnected from the Reg/Rec, start the engine, and with the voltmeter, measure the voltage (on the Volts AC scale) between the three leads from the alternator.
(A to B, A to C and B to C). All readings should be 60vac or above.
This is all with the engine revs at 5k.
If you have already tested the alternator in this fashion, I apologise for wasting your time.
Kwackboy...yes it was at the top of the coils, but at the rear of the unit.
Cheers
