When I got my 120, the towing socket had been cut off. I wired on a new socket, but nothing was live on it.
After some investigation, I discovered the trailer wiring harness had been disconnected from both of the rear lights. I reconnected that, and now onto the next problem.
The indicators now flash twice as fast as they should (same as when a bulb has gone!).
The towing indicator relay (see pic) is getting 12V on the red (UB+) and ground (31) is OK. The IL and IR pins go to 12V when the indicator(s) are on; and the OL and OR also go to 12V to power the rear indicator. That all sounds OK.
However I also get 12V on AL and AR (trailer indicators) even though there is no load on them. Its like its expecting a trailer then flashing fast because there is no trailer bulbs. Should the relay always be putting 12V to AL and AR even if theres nothing attached? If so, whats the real point of it - why not just join IL=OL+AL and IR=OR+AR? Is the relay buggered, or any other ideas?
I assume the fast flashing was the reason it was disconnected in the first place...
Thanks!
