I don't drive my truck very often so the batteries are a pain to maintain. I recently got a new set under warranty so I decided to go ahead and install manual disconnect switches on them. I did that yesterday. In the process, I noticed the truck itself has a charge of 0.15 volts on it. I checked it again this morning and it still has 0.13 volts.
Where does this voltage come from? I assume it must be related to the IOD that sucks the power out of my batteries in a few weeks. Is there some sort of rechargeable battery in the radio or computer?
