electrical gremlins are back

I checked the connections last weekend and all looked good, I'll try again. And ok I'll look into getting a power probe today. The volt gauge reads 10v when I open the doors with the key off, and then 12 with the key on. And sorry 67dart273, I just didn't know whether people would see my update. And I have the wiring diagrams online that I've been looking at so much I almost feel like I've memorized them. I was reading the MAD article and am strongly considering doing that tonight. Should I do this MAD upgrade first and try and solve the problem?
