My converter keeps by house batteries charged while my engine battery along side it goes dead when in storage. Why can't I put a jumper across for the converter to also keep the engine battery charged?
No real reason you can't except you will need to manually install and remove. The devices linked essentially do the same thing but automatically.
You wouldn't want to leave the jumper in place when not connected to shore power.
BTW, this is the travel trailer section. It must be a unique travel trailer that has an engine starting battery. :B
