The alternator on my 1970 TR6 is not registering a charge at the ammeter.
It does register a discharge, i.e., when starting the car. When the engine
is running, the ammeter needle does not go into the charge (+) area. It
stays neutral, i.e. pointing straight down, right in the middle between (+)
and (-). The ind light in my tach does not go on either. I replaced the
bulb with a working one and it still doesn't go on.
I had the alternator overhauled by a local shop. They replaced the
rectifier(?) and regulator. According to them it bench tested just fine.
I reinstalled it in my TR6 and started the car. No charge! The ammeter
was overhauled by MoMo's in New Mexico. I would normally assume that both
ammeter and alternator are working. But given the quality of some of the
work I've had done at other places, I don't.
My question to the list is this:
Is there a way I can test the ammeter and alternator to see if both
are functioning properly?
If both are OK, any idea why my ammeter shows only a discharge?
Why my Ind light does not go on when I turn the ignition on?
I have printed off the VTR pages on Alternator Diagnosis and will peruse
those tonight.
BTW all my other gauges and indicator lights are functioning properly.
Thank you very much.
