Hi Ed, thank you for replying. On my bike they are just turn signals. I am going to dig into it this weekend and trace the wiring.

No Problem. The fastest thing to check would be to check for continuity to ground from the bulb socket to the frame. Because both went out, it's more likely it lost ground than power. If you don't have continuity to chassis ground, you know what to look for.
You could also activate the turn signal and put one probe of the meter (set to volts) on the socket positive and the other to ground - this will tell you if power is getting to the socket.

Update:

Frustration level is at all time high UGHHHHH.

So I traced the wires from the rear turn signal sockets, under the fender to the socket under the seat. I unplugged the socket under the seat and tested for continuity on the purple wire and the black wire. They are the ones going to the rear turn signal sockets. They tested fine, no open wires. I then traced the other side of the socket into the large wire bundle that goes to the electrical box. The purple and black wire look like they go to the plug that attaches to the turn signal module. I tested for continuity there, no break in the wires. I also tested all of the fuses. They are all good.

I then figured it was the turn signal module, so I talked a buddy into letting me take his off of his bike (same part number on both). When I plugged his in, my front turn signals now blink, they didn't before, but I still do not have any power at the rear turn signals.

Any other ideas on what I can check? I am at a loss.

Thank you in advance for trying to help!!!!!

PS-The original problem occured when the wires under the fender got chaffed while I was riding.

Trace the wires back from the turn signal module.
Get out the voltmeter and read the voltage at each connector working back.
When you get a no voltage reading you know where the issue is.

You must check the circuit while it has a load on it.

Cool

Thank you everyone for getting back to me.

Problem solved, I feel like such an idiot.

It was the turn signal module, it was fried, I put my buddies in and it worked. I never realized my bike only has turn signals in the back, they are not running lights, hence why they only have two wires. Stupid me, never realized that.

When I put his turn signal module in, everything is working as it should be. Front's are running and turn signals, rear are just turn signals.

Sorry if I wasted anyone;s time and thank you again for your help.

We`ve all had those projects where at the end we thump our forehead with the palm of our hand...at least I have..

Glad you got it fixed, thanks for the follow up.

Nice troubleshooting. Glad you got it figured out and back on the road...

Something I learned (the hard way, naturally) many, many years ago, is that when I was checking for continuity, I would also check for shorts to other wires and ground at the same time especially if I had repaired damaged wiring. Also, I got into the habit of routinely checking voltage with the circuit closed whenever possible...high resistance shorts and bad connections may read line voltage and wiring may indicate continuity with my high impedance Fluke DMM but the circuit may not carry the current. Got burned on that little gotcha many times.
