Question:

I have a Curt 56196 2 wire to 3 wire converter wired between my motorhome and my 2002 PT cruiser. The brakes and taillights work but when I turn on either of the signal lights, both lights come on and blink on the car. Any suggestions?

Helpful Expert Reply:

The potential issues with your 2002 PT Cruiser signal lights continuously blinking could be a ground problem or bad converter.

First, I would double check all of your electrical connections to ensure secure connections. Secondly, test the wires going into your converter box and wires coming out for the correct signals. A circuit tester # PTW2993 will be beneficial when checking your wiring ground. See picture to the right.

Input:
Right turn and stop = green wire
Ground = white wire
Left turn and stop = yellow wire

Output:
Right turn only = green wire
Stop = red wire
Left turn only = yellow wire

Please note that your running light circuit does not run through this converter.

And thirdly, check the ground points on each of the lights and on the motor-home. The lights usually ground through the mounting studs. If there is any dirt, corrosion, or rust it could cause a bad connection. You will also want to check where the light bracket mounts to the motor-home.

I have included a instruction link on testing ground for you as well.
