I have a 51' CJ3A and have it running with a 12-volt electrical system, including the original generator which was rewound and rebuilt for 12-volt....In checking the output at the battery with the Jeep idling I notice a voltage of 12.36 but when I run it up about 1000 rpm, the voltage at the battery only rises to 12.40 volts......dos this sound sufficient? I notice when i turn on the lights there is a pretty heavy draw and no matter how much I rev the engine the amp gauge never rises to the positive side of zero......time for an alternator?
