Rear Turns/Ignition switch question, 56K no go

My rear turn signals do not work, I just got the bike and I'm trying to figure out what is what. I am going to check the fuses today. But could it be the relay?

Check the bulb if you haven't done so. Then check the connections under the seat. That may be where the problem is. The rear side lights are supposed to be on only when the turn signal is on.

I looked at the bulbs and they didn't look burnt. The right signal wire goes into a wire nut and then into the factory butt connector. I removed the wire nut and made sure the bare wire was not touching. I tried to hit the left signal and it still didn't flash for that side. Or does the right have to be connected correct for the circuit to be complete?

I haven't had any trouble with my turn signals, so I am not up with where the fuses are.
I am sure some one here can guid you in the right direction.
Sorry I could not help you.

I'm at work, and don't have the bike here, but the turn signals are a fairly simple circuit. Each rear turn signal has 2 wires. All the wires are color coded, so it is impossible to hook them up wrong. There are no wire nuts in the factory wire harness, which means someone has messed with it. Before you do anything else, locate the 2 wires coming from each rear turn signal, connect one to 12V, the other to ground. (polarity doesn't matter in this case, the light bulb doesn't care which way the current passes through it) If the lights come on, then the lights themselves are ok, and so is the wiring up to the point where you connected it to power and ground. Try that first and see what happens. Also, what about the front turn signals, which also serve as running lights. Do they come on? Does the indicator on the instrument panel come on? Keep in mind that with the stock flasher unit, both turn signals on each side have to work in order to create enough resistance to make them flash properly. Jerry.

The front light up, they do not flash nor does the indicator light come on when using the turn signal switch. I will test the wiring when I get home.

What year of bike? do you have a Multi Meter and a test light (if not these would be the first two tools to buy as the biggest problems on these bikes seam to be electrical)?

You could have several different possibilities why the lights aren't working. Starting with the simplest... your flasher is out... depending upon the year, the self canseling switch might be broke, turnsignal switch itself might need to be cleaned, bad connections. Then on to harder more less likely causes.. broken wires, bad grounds might even be a bad 4 way flasher switch... make sure your fourways aren't on and that the brake switches aren't activated... do you break lights work?

Ok I did some testing last night, I connected each tail light to the battery directly. The right side works, the left doesn't. So it sounds like I may have one bad bulb. I then looked at the relay, it looks they did some sort of splicing and the one terminal is too short to make another connection, so I am just going to remove the terminals and put a spade connector on each end.

Remove the amber lens screws and push the bulb in while turning (counterclockwise I think, but not positive). If the base has corroded, it can get sticky. Might want to wear gloves in case the glass breaks. If it does, use needlenose pliers to remove. When it's out, remove any corrosion with emery cloth.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!
