In-Reply-To: Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii"; format=flowed The voltage will drop below 13 volts when the alternator is not keeping up (or has failed.

Loud enough to notice when the engine is not running, but quiet enough to be completely drowned out by the engine noise.
