Trailer Indicators Not Workng

[SeanC]

This isn’t the LED light problem.

I recently had the under-bonnet auxiliary battery removed and replaced by 2 batteries behind the second row seats. So I had planned to pickup my boat this weekend. I had the brake controller disconnected as I didn’t use it and also chasing down a parasitic battery drain.

Plugged it in. No power. Took it to the auto electrician who did the batteries on Wednesday. No rush just need it for the weekend. They got to it today. Had not reconnected brake controller power wire. All good. Pick it up at 4:50 pm. Oh by the way the indicators to the trailer aren’t working.

Took it home and connected up the camper trailer. Brake and tail lights working but not the indicators. Indicators on the D3 work. Can’t easily access the tow bar fuse box because of my rear drawers. The Haynes manual doesn’t list a fuse for indicators in that fuse box. I have a module to use when towing a trailer with LED lights. It has always been off as I have never towed a trailer with LED lights. Still off.

If I don’t sort it this weekend. Will be another week before I can pickup the boat.

Any Ideas.

So with almost dislocating my shoulder I managed to pull the fuses in the tow bar fuse box.
the 5amp fuse second from the bottom has blown. Listed as RH Tail-lamp, but hopefully is the problem.

I think mine did something similar and I think I put a 10A in there and its been fine since.

Yes replaced fuse second from the bottom and all is good.
