Will Having Breakaway Battery and Dump Trailer Battery Connected Cause Problems

Question

Question:

I have a dump trailer. I use the constant power from the 7-pin harness to charge the Breakaway module and the battery needed for the dump trailer pump. When the trailer is disconnected from my truck the Breakaway module is charging itself off of the dump battery. Will it constantly being hooked up hurt the Breakaway module and also kill the battery on the dump trailer?

When two batteries are connected together they will attempt to balance the same voltage so if one battery was less charged than the other it would draw amperage from the other one till they both balanced out. It really won't hurt anything, but if you drain the dump battery from using the dump feature you will eventually drain the weaker breakaway battery too as it struggles to charge the larger battery. It would be probably your best option to have the two on separate charge wires.

If you already have a breakaway switch and trying to find its power source, It is possible that someone could have wired the breakaway switch directly to the main battery on the trailer but it does not come like that from the factory. The breakaway…

I would start by checking the condition and level of the brake fluid. I typically recommend flushing and replacing the brake fluid on these types of units every year no matter how much the trailers are used. Brake fluid can absorb moisture which will…

Answer 11

It sounds like there is a short somewhere in your trailer wiring that is causing the #K71-651 to run. Unless the actuator itself has an internal problem the only way it is going to activate is if it senses that a truck is connected. The black wire of…

It sounds like there was bleed-over from one of your trailer connector pins to your brake output pin. This can happen with just a little corrosion, so it doesn't surprise me that you unplugged the trailer and plugged it back in and the issue…
