jock..
just another thought worth noting as i,v recently solved some one,s niggling problem
when fitting ,,idiot,, lights.
if you use LED lights the ign warning light will need a resister wiring in with it otherwise it wont have enough resistance to exite the alternator cuasing no charge
i know someone who has just fitted two new alternators on a hotrod project
when it was the LED that was caursing the problem..
