Little blinking red light on sleeper ac control panel

not sure, what your talking about. i'm kinda green at working on trucks to be honest with you.

 

There charged but there may be a bad one in there. Do you think that can cause it? a bad battery in the mix that is? When I first got the truck I saw that the lights weren't coming on in the cab for the a/c control panel so checked the fuses and that fuse was pulled so put a fuse in and they came on, i thought that's funny why was the fuse pulled well now I know. there weren't actually any batteries in the truck when i got it. i put new batteries in it and let it sit for a week or so came back and the batteries were deader then a door nail to the point 1 or 2 of them had crapped out on me. Ken-worth replaced at least one of them I can't remember if it was 1 or 2. I keep the charger hooked up all the time now. I found the draw was coming through the power control relay so I keep that disconnected and have also pulled the fuse that keeps the lights on the bunk a/c control panel at least until I can find the issue.

 

I've cleaned my battery terminals also as they did need it but not sure if that's fixed the problem. I need to get the multi-meter out again and see if there's still a draw. haven't been able to find any grounds on the frame yet. I've looked everywhere. seems the cables from the battery's go directly to the starter and the go through the deal at the firewall from what I can tell anyways. I'm thinking those 2 connection at the go through need to be cleaned also.

It's funny you say that. i was talking to a guy the other day and he said I need to put an aftermarket cut of switch on it so when not using it just shut power of manually at the switch. but it still doesn't explain why my uncle pulled the fuse to that ac control board in the sleeper unless of course he had bad batterys and didn't realize it. i've recently put new batterys in it but as i said in previous post i let her sit for a week or so and it ended up draining them dead and after charging them back up i'm thinking one or so of them are bad now. so you think new batterys and a new cutt off switch would fix this?
