Hello all
Does anyone have advice for wiring up the gen light on the dash when using a alternater? Bloke that sold me the alternater said to run a ignition power wire through the light, then off to the alternater to excite it into charging the battery. Its not charging at the moment. Any help would be good as I am afraid of damaging something.

Should not be necessary - does your alt have inbuilt or separate reg?

Andy,

As Ken says, not all alternators require an exciter, however if you are using one that does,  I did some research to work out the exciter circuit some time ago when I was using a camira alternator.

More in the thread below, although some of the problems I experienced were from incorrect pulleys ultimately.

I did post up some part no's of resistors or bulbs you could use.

Cheers

I think it has an inbuilt regulater. The original wire from the gen light has 12volts of power. I ve hooked it to the w (warning, I guess) lug on the alternater but it still wont charge. Does the alternater need to be earthed?, as mine is mounted through rubber cushioning mounts, so its maby not earthed.

YES!!!
Connect a wire from alternator body to engine block, minimum size same as alternator (+) wire, and as short as practical.
Make sure of a firm bolted connection, with proper terminals.
Should fix it immediately if there are no other burnt-out bits.

Success at last. It was the earth. The aircon mount ive used is soft mounted, and the alternater sits on top with a soft mounted adjustment rod. All good now. Thanks for your help.
