[Healeys] Testing Voltage Regulator

[Ron Fine]

Is there an easy or simply way to test my regulator to see if it is putting
out enough current to keep my battery charged?  I know my generator is working
but my 3 year old Optima battery ran down after a long drive with my regular
head lights on.  I think the generator should have put out enough charge to
run the lights and keep the battery charged during the 2 hour drive.

Thanks,

Ron Fine
