Voltage draw??????
I've got a voltage draw and can't seem to diagnose where it is coming from. Does anyone have any advice?
thanks
PS: 81 f-150, 351W, pretty much stock except no emissions are hooked up, and I have an Accel Super Stock coil. brand new Alternator, voltage regulator and all fuseable links in the engine compartment by the starter solenoid have been replaced.

how much
Most vehicles have a small amount normally. You can take the positive terminal off of the battery and using a digital multimeter measure the voltage between the battery and the removed terminal. If I remember right less than 6 is considered to be minor. You might have to leave the meter on and unplug and replug things until you find the culprit.

Go buy yourself a test light for $2 because I'm gonna tell ya if it glows at all, it's too much.
Beyond the obvious pulling fuses method, I recommend pulling the + wire to the alternator. A bad diode will cause a draw.
Good luck and keep us posted.
