That is what I have. Thanks for the info on that third wire though .

They're off. Looks like a jumper between the cable and battery needs to be in place for 20 to 30 minutes to give computers time to cycle prior to performing the fuse pull test. I hadn't allowed enough time when I tested the circuits earlier.

I bought a new battery. I'll install it tomorrow and retest. The right way this time.

So far so good with the new battery.

Thanks for all the help.

Happy meal: How did you solve the problem. I'm having the same drain through the 50a batt fuse. Thanks, MP Wood
