Hi guys, just wanted some help please. We have lost power to our Conqueror 490 rear lights including brakes, lights and indicators. We have power from the vehicle and in to the conqueror through the plug but nothing after that. All the power inside the conqueror such as tv, light etc are working, does anyone have any suggestions? Could it be a fuse or a relay, if so where is it located? Many thanks for your help!

Hey Sklinky,
Sound more like your trailer 7 pin wiring has been severed if all your other power accessories seem OK. Trace it out from the plug back, it runs along the chassis rails and enters Just in front of the wheel on the near side then runs along under the lip of the bed then exits out through the back wall behind the tail lights. Maybe you've damaged the cables around the suspension swing arm? Or check in behind the tail lights as they are quite messy in their wiring.
Check the wiring in the plug too just in case the cables been pulled and broken it??.
Good luck with it, let us know how you get on. It's been a bit lonely on this site lately.

Hi Sklinky

Got your PM.

I had this happen to me in Karijini a couple of years ago. It turned out to be the vehicle plug, not the trailer but, I ended up running a complete new trailer circuit when I got home because I didn't like what I found. The trailer lights (brake, indicators etc) are a completely separate system and are not linked in anyway with the accessories inside the trailer. If it's not the vehicle plug, as comjero says above, the wire may be damaged somewhere and is causing a dead short.

FIRST AND EASIEST - Get another trailer or van and plug into your vehicle plug - work through the lights and see if they work. If they do, it rules out your vehicle plug. If not seek a repair on it from a trailer shop (earth is probably the problem).

SECOND - Open the plug and check its condition - corrosion, poor connections etc. give it a clean while its open. If you have a multimeter, plug the opened trailer plug in and check for continuity across each circuit connector.

If no success, rig a simple power supply (use positive and negative feed - don't rely on existing earth) and check each circuit in the trailer and see If the light comes on (you won't blow the lights as they should be rated 9-32volts). You could also do the same but cut into the wire at one of the lights at the rear to check its not the lights. (Use a scotch connector to save cutting the wire - then you can cut your wire, insulate and repair properly at a later date.

If the lights don't light after that, I would suggest that you may have an earth fault - given all lights have stopped working, I would look there first as it is the only common between them.

Look for obvious damage to the trailer wire - first at the plug then along its path - a) where it passes through the draw bar, b) along the chassis, c) into the trailer, d) along the bed e) through the back wall. If found open up and repair.

If nothing found, look for where the trailer plug and wiring circuit join. You may find several joins as the wires go from Australian to South African Wiring (mine had several of these joins which is why I rewired the trailer) open them up and check for condition and corrosion then repair or replace.

If all/any of the above doesn't locate and help solve the problem, I will have to do some more thinking.

I have sent you my mobile number so you can give me a call tomorrow. Getting ready for the super storm tonight at the moment.

Cheers

Anthony

Hi Anthony
Give me a call for coffee when on your way down my place. A great idea to get together again in WA.

Cheers
