I'm running a 1 year old Optima yellow top battery so I hope the battery is not the issue. I'll check for amperage draw next time I feel like monkeying around with it, I just wanted to make sure that this wasn't an unheard of phenomenon. I have the original monochrome unit and I don't drive the truck a ton anymore since I have a work vehicle 5 days a week, it just seems weird that it would kill a mostly charged battery in 4 or 5 days. If it helps, my truck drew .43 volts with the Gryphon unplugged which I'm sure is mostly the constant fuses in my truck that are keeping the clock and radio set and the alarm running, but an 80% drop when the Gryphon gets unplugged seemed like a lot.
