Tekonsha P3 warning

webers3

Any Tekonsha P3 users encountered “OVERLOAD NO BRAKES” warning?

After over 2 years of flawless performance this warning started to come up on the last trip with my 320s when applying the brakes. eTrailer says there may be a short someplace, among other possibilities, and provides a troubleshooting guide that is really for a “tech” to follow. If anyone encountered this problem please share you experience and a possible solution. Thank you

Possibly a bad brake magnet? Maybe wire at the wheel disconnected? I would start looking around on the trailer itself for obvious brake wiring problems.

If you have a helper, activate manually the controller while helper listens at each wheel, you should be able to hear each brake engage.

@N7SHG_Ham thanks. Hear buzzing on both sides so I guess the magnets are engaging

@webers3, I did a quick Google search on your question.  Maybe you will find some helpful answers by reviewing these links:

And there is this info from the FAQ on the Tekonsha web site (regarding the P3):

Shows "Overload No Brakes"

The P3 detects excessive current on the brake wire (Blue wire). Possible causes:

• Short to ground on brake wire.
• Shorted brake magnet.
• Moisture or corrosion in trailer connector.
• No voltage on battery charge circuit (for electric over hydraulic brakes only).
