You guys are making it WAY too complicated. Do what I suggested in post #30 and you will find your problem, took me 30 minutes, five broken fingernails pulling fuses and three blisters... BTW, I spent most of my military and civilian career troubleshooting electronics junk so I have all the fancy test equipment but the homemade test lamp beats 'em all for finding a current drain. I keep one in my truck and classic cars. Also, I had several Optima batteries and will NEVER buy one again. If you run them down and don't recharge them correctly, they won't take a charge. I burned up an alternator trying. Google "how to charge an Optima battery" and see if that's how you recharged yours, could be part of the problem. Just my $0.02USD......
