Not sure what to use as a subject but I'm trying to get an idea of how much current does the computers and other devices such as clock, use when the engine is not running. This would be a standardish, 2000 and newer, Ford/GM/Dodge diesel pickup.
I ask because I typically only drive my truck every few weeks or even a month. So I'm seriously considering mounting a permanent solar panel on the roof. And I'd like to size it so in winter it'll at least keep up with the current draw on a sunny day. Or maybe a bit more than that even.
Yes, I could keep it plugged in with a trickle charger but the last time I read those instructions at the local parts store they stated they weren't designed to be permanently attached to the battery. Presumably because if they weren't plugged in to 120 VAC they would draw some current.
