Turn signal oddity..

Hello again!

So you've all helped me through the rear spline lube and the brake replacement on the front and rear.. but the newest problem has me stumped!

I bought new rear turn signals recently after one broke on my ride to Washington DC in May. The new signals have been working out great until late Saturday night when I was riding home and realized the bolt holding the housing to the bracket had come loose. So I got her home and started tightening the bolt when it snapped off- broke clean through. I ran up to Iron Pony just before they closed on Sunday and bought a new set, then came home and put the new signal on to replace the one with the broken bolt. Snipped the old one off, soldered the new one on, covered with heat shrink and some electrical tape, and mounted the signal to the bracket to test with the power on... Emergency flashers work great, right turn signal works perfectly, but the left turn signal (the one I had to replace) now turns all 4 signals on instead of just the left 2. I really don't get how this could happen! I've totally separated the wires so there is no crossing, could I be missing something else? Could the switch be the issue?

I'm hoping someone here can tell me something simple I'm overlooking. I plan to head to the garage shortly and try to re-wire the new signal. If that doesn't work, I suppose I'll be re--wiring the whole dang thing! I really hope someone can tell me what I'm doing wrong to save the frustration and aggravation!

Thanks in advance! You all are always so helpful and I'm privileged to be a part of this great group!

Electrical gremlins like this are definately not my forte.

My only suggestion is to desolder the new signal and try the other one in the new set to see if there is a fault of some kind.

Maybe try a test light on the bare wires before hooking up the second signal.
If it still flashes all 4 lights you know it is in the wiring harness, not the new signals.

Good luck.

I tested last time before I mounted everything and it worked perfectly. It wasn't until I mounted the signal that the problem started.

I figured out what the malfunction is, just not sure how to solve it yet!

The problem appears to be the mounting system and requires a little back story. Some time ago, I put jumbo saddlebags on and had to relocate the turn signals on the rear. I did so by cutting brackets from some angle aluminum stock and everything went just fine, also improved the look of the bike IMO. The brackets are mounted to the license plate bracket, held on by several washers and a nut. Apparently, these turn signals are passing enough current through the metal that it's lighting up the other side!!! What's more weird about this, is that it only happens when I turn the left signal on. After pulling either signal from the bracket, the problem stops. I put a felt washer on each bolt securing the signal bracket, but apparently the bolt is conducting enough juice to do this on it's own. Would it be worth putting a piece of a shop rag in there to buffer the metals? This is such a strange occurrence, especially considering the fact that the signal I replaced was the exact same make and model as the current ones, but there were no issues until I replaced the broken one!

Oh. That's enough to make a bishop kick out a stained glass window!

How frustrating! And embarrassing! Let me go wash the egg off my face now.

Thanks! That was the ticket. All is well with the Force once again!
