I was wiring up my Prodigy 2 brake controller and upon initial connection, it was lighting up fine. Then, without the P2 connected, I was weaving the harness under the dash (plugged into the pin-out at the kickplate) and bumped it on the steering linkage and saw a subtle spark. Now the P2 doesn't light up at all. All the fuses under the hood and in the cab above the e-brake test ok on my meter. Even the one labled "towing" under the hood passes thru my meter. Any thing I may be missing?

The pins plugged into the P2 only pass thru my meter when touched to white wire.

All signal lighting on the trailer works when connected by the 7pin.

Any thoughts?

 

could the adjustments on the controller gotten turned all the way down ? this happened to me on a truck at work. i believe it was the left side adjustment . i think the controller was a prodigy.

 

How was your brake controler protected (fused) ??

Where did it draw power from???

Are there any other circuits not working??

 

I'm trying to find a blown fuse...nada

the P2 was not plugged in when I saw the spark, just it's harness. It draws power from the factory towing package pin-out under the kickplate by the parking brake. From there, I have no idea.

All circuits seem to be working, trailer lights/signals work fine.

 

Found another little 3rd fuse box under the hood (had too much dirt on it to notice it was yet...another fuse box.) This little fuse box had yet another 30A fuse labeled "towing" but it had one labeled "towing brake".
Bingo

 

thanks for sharing the fix. Too many folks never own up to the repair. Glad you figured it out and told us what it was, this is how everyone after you learns.
