As a rule a 12 volt battery should read a little higher than 12.4 volts?
Yeah I know that. As I have said many times, I have 2 issues going on.
1. Breakaway battery box light reads recharge, but electrical tester says 12.4 volts. Thats one of the issues.
2. Brakes suddenly became weak. That’s the other issue.
I’m very aware the battery box is not related to the brake loss.
Your 7pin connector has a ground wire in it. So your hitch/ball shouldnt be the ground path.Been there, done that!
Look for rust on the 2" receiver housing. In my case, the Dodge Ram 2500 came with a 2.5" receiver with a 0.5" spacer so it would accept 2" receiver components. That sleeve and the trailer hitch connection collected water and rusted, breaking the circuit to the trailer brakes in my case. Like a light switch some turned off I went from excellent brakes to absolutely nothing!
12.4v is a dead battery. It should be reading higher and more like 13+ if the vehicle is running.Breakaway battery box light reads recharge, but electrical tester says 12.4 volts. Thats one of the
Yeah, I know it’s marginal. New battery in late March. Hard to believe that far gone already12.4v is a dead battery. It should be reading higher and more like 13+ if the vehicle is running.
