Question:

Hi, we are a new user with a toad on our class C. We have the brake system set up correctly with no error lights. When we begin to drive the TG controller gives us an report message saying “check power connections on brake”. When we pull over the unit has power light on. Can you help us troubleshoot please?

I took a look through the manual for the Blue Ox Patriot 3 Supplemental Braking System and found this under the "Check Power Connection" error.

"This message will appear when the brake reads an input voltage below 10V. This means that the brake has detected that the towed car’s battery is very low (OR the brake is no longer receiving power from the car receptacle) The brake will go into an idle state and not work for normal braking. It will work in the event of a breakaway! When it is safe to do so, pull over and inspect the towed vehicle. Check the indicator light on the power cord to see if the brake is receiving power. If this is the case, check the towed vehicles car battery voltage. If power is restored, the status light will change back to green, and you are OK to resume your trip."

Please note that some vehicles require a battery charge line to be installed as the toad's battery drains while in tow so in which case it sounds like you might just need to install the Roadmaster Battery Charge Line Kit for Towed Vehicles part # RM-156-25.
