Does Brake Buddy Select Supplemental Braking System Drain Vehicle Battery

Question:

Im flat towing my 2008 Honda Odyssey behind my motorhome and using a Brake Buddy. I keep getting a dead battery in a short time. Troubleshooting has eliminated the BB and the wiring harness from the MH. Battery chargers dont help. I have the Nav system in this van but I have everything turned off. Will this work in my Odyssey and which fuse do I pull to use it?

The Brake Buddy Select 3 part # HM39524 like you have plugs into a power outlet in the tow vehicle to power the brake setup. So what that means is that it's draining your vehicle battery as it's being used.

Using a fuse bypass won't prevent this from happening. Only solution is a battery charge kit like the part # RM-156-25 like it sounds like you tried which will keep the battery topped off so that when it's being used it will hopefully recharge.
