electric brake problem

I've heard that these have a problem with this happening.

There was a solution developed that involved a Diode in the circuit somewhere. I'd say you'll get someone on here who knows more about it.

Hi Barry,

The Tekonsha Voyager had a problem but not the Tekonsha Prodegy. That is not to say that it has not developed a problem.

There should be an auto reset fuse in the main power line to the brake controller. Check this out as it should be somewhere along the main power line. Trace the red wire back from the unit.

If replacing this fuse you need to replace it with an auto reset fuse of 20 or 30 amps capacity.

If you have a good auto electrician close I would let him have a look at it as the problem may be somewhere else other than the controller unless you are pretty handy around electrics.

You say you are in Gladstone, is that Queensland or NSW ??.

Cheers, Bruce.

Black is the power wire supply from the battery via an automatic resetting circuit breaker.

Red is the brake light switch sensing wire.

Blue is the wire to the rear lug and brakes on trailer.

White is the earth to vehicle body or chassis Batt negative.

Funding faults/testing.
If yours doesn't work make sure it has 12v battery at the black wire in the Tekonsha plug.

Red wire in the the Tekonsha plug should only read 12v Battery when the brake pedal is pushed.

Blue wire goes to trailer plug and it should have no voltage/current in it unless plugged into controller and brake pedal pressed.

White should be firmly connected to earth at all times.


Trailer base ---- it's blue wire PIN 5 should be firmly screwed in and tight in it's pin and no other strand of the wire cable touching the trailer terminal. Pin5 service brake.

Make sure white of trailer base is in PIN 3 and the pin is connected securely to a good earth.

A common fault is the stray strands of wire which touch each other, in either the vehicle base or the trailer plug.Check both.

If all checks OK then it may be a faulty Tekonsha.
Iit may be using it's 12v input via the plug when connected to the Tekonsha to feed power back up the red wire and therefore activating the brake circuit.

It is in this wire, the red wire that a diode can be added to prevent such back feeds, but the Tekonsha shouldn't be doing it.

Hi Bazz

I had a problem with my prodigy 2 acivating the van brakes intermittedly , while driving on a flat road with no brake applied by me. After stopping and turning off the ignition, the brakes released, then when I drove off, all was ok. this happened a couple of times, so I took my vehicle to the business that installed the unit, and they replaced it
no questions asked, saying there have been a few prodigy 2 units giving trouble.
No problems since.

There is a lifetime warranty on Tehonsha controllers (unless you foolishly imported it yourself, that makes you responsible for the warranty.) Check out your wiring as instructed above. If everything is OK with the installation then take it back for warranty replacement. If someone supplied and installed it, take it back to them for warranty.
