Has anyone ever identified a rogue current draw on the battery when parked
if so, what is/was the source? I think I have something pulling my battery down more than it should when car parked a couple days. I went through every fuse with a multimeter a while back, but didn't identify the source. Was wondering if there is anything in particular that I should focus on.

Have you load tested the battery, or had the alternator tested? Skid though he had a draw
turned out his Optima Battery was crap. Sometimes bad batteries can masquerade as a charging or draw problem. There's also a crapload of relays, modules, and keep alive circuits that could be drawing.

I thought mine was my radio and would turn it off before turning the ignition off just in case
but after I just replaced the battery after only two years I think it might have been a bad battery as now it doesn't seem to do it and my voltmeter seems to be running much higher than it was...it was always within the tolerance range but is much higher now. I real here where some had experienced it but never a real answer to the source(s)
p.s. I also toyed with the idea that it was my solar fan...as it runs all the time, but again no problem since the battery replacement (odd as the OEM lasted five years)

I still have the problem, I really think I'm going to put a new altenator on it. If I let the car on a charger over the weekend the car starts really good for a week or so, then "slowly starts starting slower"(say that fast 5 times) : )
