Default Has my alternator gone bad?
I was just driving my Cobra and noticed that the electrical system voltage shown on the voltmeter was varying substantially with engine rpm. At idle, the voltage was 12-14 V, and at 3000 rpm the voltage was 18 V. Is that an indication that the voltage regulator in the alternator has failed? It is a single wire type alternator. Is it something that can be repaired or do I have to replace the entire alternator? Thanks.
