{"replyTo":"","text":"There could be a number of reasons why this is happening. I mean it could be a failing alternator/voltage regulator, faulty voltmeter gauge, wiring issue to voltmeter gauge, poor connections on the alternator circuit. Best advice is to have it checked by a mechanic.","replyToPid":0}
