I had a problem with my '62. It was charging at more than 15 volts all the time. I was able to determine that the cause of the overcharge condition was a 1.5v drop at the regulator compared to the battery. Following help from others on this board I was able to determine that the drop was somewhere inside the car. Most likely the bulkhead connector, ignition switch or connection in the harness where all of the 12v sources are connected. I cleaned the bulkhead connector but the problem still existed. So I decided to isolate the bulkhead connector from the charge circuit by installing a relay under the hood. I used the blue wire from the bulkhead connector to trigger the relay which is fed directly from the starter relay. Charge voltage is now normal. I left the ammeter connected. It now shows a constant slight charge condition all the time. I think it may be because the 12v stuff under the hood, mostly the ignition system, is now upstream from the ammeter. Can anyone verify this? I want to make sure there isn't another problem someplace before I replace the ammeter with a voltmeter.
