tailer spoiler lites

Postby m2102 » Mon Aug 11, 2014 5:20 pm



my trailer has a spoiler that has lights in it and would like to hook them up for tail lights. I have tried every hot wire I could find and the last thing I tried was hooking to the side marker light. like all the other ones I tried the tail light would come on and when the brakes are applied they go dim. when the turn signals are turned on the light bar blinks. have tried with key turned to on and with it running. I am at a loss. do I need to put an in line resister in and where would the best place be to place it. I have a 4 flat plug to hook up to bike. I should mention that the tail lights do come on they seem to be brighter than the trailer lights. for no just going to unhook till I can get a solution

It sounds like you have a bad/no earth. Work out how the trailer is earthed, and then make sure that the earth wire has no corrosion, and while you are at it, all the other connections. Use a multimeter to check the voltages as you check out each wire and connection, just to make sure that the jolts are getting through.

To test whether it is the earth or not, run a single wire direct from a known good earth (not the tupperware), and run it back to the trailer. With the lights on, check that they are working.

Let us know how you get on.

I had that problem on my 99A. It was a bad ground in the trailer harness on the bike, the ground wire in the plug and play connector. It only effected the led spoiler. I removed that pin from the connector and fixed the bad crimp job with a new crimp pin.

from what I can tell, it looks like their is 3 ground wires, 2 on the trailer frame and one on the tongue. back by the lights, their is a cluster of splices and connectors. the wires in the back don't match the colored wires from the 4 way. really starting to think it is past do for a rewire job. at least the wires would be right.

Never seen a trailer yet that had same color coded wiring throughout. The symptoms that you describe, dimming when brakes applied, slight blinking when turn signals are on, these are common even with no wiring problems. What happens when your RPMs are high enough to charge the battery, 2,500 rpm or so? These symptoms may be totally gone when you are actually charging the battery and "riding" the bike.

Never thought of that. Since 1500s need 2k rpm to charge
