Charging issues

I know this is the only car i have ever had this happen to.

Disconnect the output wire from the alternator and see if it sparks when you touch it back to the terminal, unplug the regulator harness and try it again.

Best way hunt for a draw is with a test lamp, in series from your power source to your loads, or by disconnecting individual wires at the source and watching for the arc.

Goob, no disrespect, but doing that can kill the diodes.

I meant pulling the wire with the alternaotr powered, not the test lamp method.

Sorry for any confusion.
