Help needed on toad wiring

[Karlos]

Bought a toad finally and now checking the SeaView's trailer light connections. There is a round, six pin connector mounted in the bumper ... possibly a factory original.

Only four of the six pins have wires attached ... a ground, running lights, left/brake and right/brake. When I test with a voltmeter, the running light tests fine, and the brake lights alone test fine, and the left turn signal tests fine.

The right turn signal seem to be messed up. The right turn signal puts a flashing 12V on both the right turn pin and the left turn pin. Similar when brakes are added.

Since the RV has separate brake and turn signal lights, there must be a tail light converter box buried somewhere to get the trailer wiring down to four wires. I'm suspecting the converter has failed. Anyone know where it might be hidden? Or any other tips?

Thanks,
Karl

We use only four wires of the six wire plug, I believe you have a short somewhere.

BTW, no box that I am aware of.

It might just require the load of a tail light being connected. If there are mixing diodes in a combiner one of them might be leaky. Try connecting a light bulb between the right turn and and ground? If you have 2 lamps connect one to each side. If you have modified the TOAD with steering diodes try connecting the TOAD.

Karols-

This previous iRV2 thread and a post I made on another thread contain info you may find useful.

Ford provides two sets of contacts on the F-53 turn signal switch. One contact set superimposes the brake signal on the turn signals, and the other does not. This allows the coach builder to use separate turn and brake lights on the coach and still send the combined signals to the trailer connector, without requiring a three-to-two converter.

If I was a betting man, I'd bet that you have a short, as mentioned previously, or an intermittent ground, in either case likely inside the hitch connector.

Thanks for the tips. I'll put a load (bulb) on the pins and see what they do. If that doesn't work, pull the 6-pin connector and test the wiring going into it. I was going to replace it anyway.
