The new season is here and I'm getting the trailer ready to rock and hopefully roll, and stop.

On our 2nd to last trip last season, I noticed once in a while that I would loose my electronic breaks. Hit a bounce in the road and they would come back.

On our final trip last season, they just went out and wouldn't come back with a bump in the road.

We have a 2005 19' Bambi and it is pulled by a 2005 Chevy 2500HD. The electronic break control is a Tekonsha P3.

The display on the controler would litterally turn red and say 'No Electronic Brakes'.

Last season I went through and tried to find a short somewhere in the wiring.

I elimnated a short existing on the truck.

I cleaned the contacts of the 7-way plug.

When the trailer is all hooked up, everything functions (brake lights, turn lights, hazards) on the trailer.

When I tested the hook up to the truck with a DMM, I was getting voltage on all 6 leads.

As the season progressed last year, I noticed that I had to continue to increase the amount of juice going to the electronic breaks to get any sort of breaking power.

Access to the wiring in the electronic breaks is not easy to get to. So I haven't been able to test for a short from the plug in to the truck to the breaks.

Also to be frank, the manual that came with the trailer isn't super clear. It looks like it is a photo copy of a photo copy of a photo copy.

Any help or suggestions on where to hunt down my lack of breaks would be most appreciative.

Thanks,

Chris
I would work your way back from the trailer and I would check the wires from the wheels forward. If your increasing voltage through the season to get breaks to grab I bet you have a small short I am betting from the wires to the wheels near the wheel itself.I noticed on my trailer the wires feed through the back side of the wheels through a groment to protect wires. This gromet I had to change because it was falling apart. The metal of the wheel was rubbing against the wires. Also check all ground wires even though the lights all work the connection may be not enough to give the brakes the connection they need.
