So after getting my batteries bench tested again, they both came back fine.
I seem to be having a problem with going out to start the truck after a 2-3 day period and my batteries are dead.
I hooked up a DVM to the driver side battery with both batteries connected and I am getting about 1.18amps at intial contact which drops down and holds steady at about 0.96amps. Started pulling some fuses and nothing happened. Pulled the 10amp radio fuse and this dropped the amps down to 0.86amps steady.
So I found this to be kind of weird that no other fuse is causing parasitic drain. I disconnected the positive terminal from the passenger side of the truck and the amperage shot down to 0.25amps steady on just the drivers side battery connected.
I got thinking about connections and went back out to the truck to determine where the 0.25amps was being generated from the battery on the drivers side without the passenger connected and it was coming from the #3 fuse which is courtesy lights. Thought this was weird because I have the lights turned off. Low and behold even after checking the glove box door to make sure it was shut, I guess the last time I shut it, the clip broke and the light remained on.
I tried another test though and ran the DVM between the positive battery connection on the passenger side that leads into the starter and I had a reading of 0.00amps, I now have readings of 0.00amps when both batteries are disconnnected from each other but as soon as I put them in line, the readings spike up to 1.18amps and hold steady at 0.96amps. This to me is confusing.
Thinking either one of the batteries is toast even though it holds a load or there is a short in the connection leading both batteries together.
What are your thoughts for the current being drawn when both batteries are connected?
