Question Prodigy reading 0.0 when braking

Took the fiver out of storage the other day. Same day took my travel trailer into storage. The brakes did not work on either rig. Failry obvious when you come up to a STOP sign, and almost roll thru it.

On both rigs the Prodigy brake controller first did not show "c" (for connected) until I jiggled the connector on the truck. Then it showed "c" , but when brakes applied only got "0.0" and no braking.

Wondering what to look for?

All advice and experiences welcome.

Just watched a YouTube video on the installation of a Prodigy Brake Controller. When the tech showed how the display shows "0.0" at the minimum power setting, it dawned on me that maybe the car wash guy turned it down. I checked it. Sure enough. The power wheel was rolled full back toward the rear of the truck. I hooked up the truck to the fiver (wiring only) and stepped on the brake with power set at minimum. Got "0.0" reading. Rolled wheel forward to full power and got about "3.7" ....without even moving. So I guess I diagnosed this non-problem.

Maybe my stupidity will, in the future, help some other frustrated person who is ready to leave home, in an hour, when this happens.

Ain't the internet great?

Joe, I did the same thing cleaning the interior of my truck. Took me a while to discover what I did.

Since you did not see the "C" right away, I would be looking for a corroded connection. Water gets into the connectors and is common for corrosion to build up. Check for corrosion on both the truck and trailer connections, although I rather suspect the truck connection. Clean the connector terminals and see if that fixes it.
