CVS 0 Posted April 22, 2019 Has any body had issues with battery's going dead during the slow season? we ended up installing kill switches to turn the battery's off while they are not being used. I have heard these trucks are sensitive when adding after market items on sucks as lights, cameras, or CB's. Everything appears to be wired in and added correctly. just curious if anyone else has experienced the same issues with these model Peterbilts. Share this post Link to post Share on other sites
Agua1 2 Posted April 22, 2019 I know that most any newer vehicle will always have a draw from the computers. I also know that some manufactures have a dedicated location for add on electronics. Adding them to an existing circuit can cause electrical gremlins. We have run into that issue where the change in voltage caused a check engine light. It was not a perterbuilt, but a freightliner. Use a DVOM and see what the draw is when you think everything is off. Secondly a trickle charger can help keep the batteries alive. Share this post Link to post Share on other sites
Pacific Sweeping 4 Posted May 15, 2019 we trickle charge the ones that we know are going to be sitting for a while and it works for us! Share this post Link to post Share on other sites
