[BILL WILLIAMSON]

To check for draws, I cut a jumper lead in half, mounted a buzzer from an old smoke alarm in the lead. Disconnect ground cable and hook the lead from the post to the cable, it'll scream like a Banshee! Then wiggle wires, disconnect stuff, or whatever it takes to find the problem. You'll know INSTANTLY when you've found it, 'cause that DAMNED THING will stop screamin' Bill W.
