Hey guys 2002 xl1200c
All lights work except left turn signal. When I turn the left signal on it lights up solid instead of blinking. The off part is it's not consistent. If I lean the bike left it will work off and on.
I replaced the tail light last year and thought it could be a short there but it doesn't change when I mess with the brake light wires.
I'm starting to suspect the turn signal module? Is there a sensor that changes the signal after a lean or turn?
If it is the tsm do I really have to take off my rear fender and everything to change it?
possible short? When handle bars are turned left or strait my left signals blink. If the handle bars turned right they light but solid. I can still make them flash manually by clicking signal button.
Do s anyone know of a common spot of a short before both left signals that the handle bars moving would effect?

My exhaust is fairly loud. But without a windshield the wind is by far louder. I wear earplugs for the wind not my exhaust. Without ear plugs at 55 I can't even hear my exhaust. Just something to consider when thinking about the volume

Look for a loose connection.
Also, when you turn the bars to the right, does the left rear turn signal go out? That will help narrow down the problem.
Do you have a FSM/wiring diagram?

I dont have a fsm wiring diagram.
The back signal and front signals are both effected and it only happens when I turn the bars right. If i turn the bars to the left they will start blinking from glowing solid.
When you say loose connection do you mean a clip or a wire that's broken?
I plan on getting inside the riser this weekend and looking but my wires are ran inside handlebars.
Where is a good place to start looking for a loose connection and what's the best way of looking?

Check where the wires exit the bars, the edge of the hole may have rubbed the insulation off one or more wire.

I've tried bulbs.

Figured it out.
I pulled apart the riser and everything in there was sound. Since how the left signal short only happened when the bars were strait or turned right I assumed it was a pulling motion that was causing the short. The bundle of wires coming from the bottom of the risers dropped bellow the risers and around the left side of the frame. The wires then went under the tank where I'm assuming they meet under the seat. There are three wires black blue and purple going into a clip with other wires. when the bars turned right the three wires were pulling the clip apart. Pushed the clip together snug and problem solved. There were too many zip Ties holding the wires together too tightly.
I'm assuming a solid light instead of flashing means loose connection?
Thanks for the help.
