Could reversing the red and white wires connected to the alternator cause a battery drain when the car is not in use, but still run and charge? Note: I'm using an alternate location for the voltage sensing wire, and I am using an "idiot light" and the existing amp meter in my '46 chevy. I completely rewired the car, and I've narrowed down the drain to the charging circuit. Last edited by paulsfc1947; 07/09/11 11:59 PM. Thanks

The sense wire on the alternator can be "hot" all of the time, but the "light" terminal must be keyed.
