I wonder if anyone can help?
I am in the process of fitting a Takonsha Brake control unit to the towing vehicle and think I may have come up against a problem.
There are 4 wires on the unit - in accordance with the instructions I have done the following:
one wire goes to ground (white) - one wire goes to the dead side of the brake switch on pedal (red) - a heavy duty one goes to the positive side of the battery (black) and finally the blue wire goes to the plug at the rear of the car and to the brakes on the trailer. This is the wire I am having problems with (I think).
When I put an electric meter to the end of the blue cable (with the brake pedal off) and earth it - it reads 12V
- surely it should only do this if the pedal is pressed? Is this normal or have I done something wrong?
Please can you help
