Hi everyone, my bike is an 09 SERG and I have a new trailer that has rear led signal lights with small led side lights that act with the signals. I wired everything with an isolator and have strong running and led brake lights but no signal lights on the trailer. The isolator is wired to the positive and negative on the battery and using a ground other than the battery ground causes a very dim running light but directly grounded to the battery, a nice strong running and brake light. I was told that maybe the signal going to the trailer signal lights may be too weak and that I should try wiring them from the bike's lighting relay wiring to get a stonger signal. I don't like to get into cutting the oem wiring but would one suggest to tap into the subharness wiring before the isolator and wire directly from the subharness turn signal wires to the signal light wires going to the bike's plug, I could individually fuse the two lines for some protection if need be. I guess I could just cut the wires at the subharness and test but if that doesn't provide a strong enough signal, then I'm going directly from the lighting relay at the fuse box, yikes. If I knew what was needed for a signal to the rear signals, I could read it with my multimeter and know for sure. Has anyone had anything like this happen to them and can share their fix with me, any help would be most appreciated. Thanks in advance.
