Turn Signals not working
The other day I took the sissy bar off my bike (93 Sportster 1200 XLH). After replacing the ground wire to the bolt, I lost both my back lights (not working at all), my right turn signal in the front (will light up regularly but not blink when turn signal is initiated) and the right indicator light will not work. Front left single works perfectly fine and left indicator light will work. Any suggestions before I hand it over to a shop? I do not have an owners manual (I KNOW! but the bike is new to me and I do plan on buying one ASAP.)
Thanks
Thanks

Check ground, Fuse, bulbs and current. Did you disconnect your battery before you started working on the electrical? (I usually don't and fry a lot of stuff) Have you checked the connectors to see if one of them came loose? Sounds like the ground isn't right or a blown fuse.

Well, my friends and I took the bike apart and could not find a fuse box. I am going to order the manual so I can find it. I checked under the left side plate and the seat, but it wasn't there.

Assuming the electrical systems were generally the same for all 93 bikes then you will not have a fuse box. Instead you will have circuit breakers. (Mine are under the dash panel) If there is a short then the breaker will trip and then a few seconds later try to reset. If the short is still there then it trips again. Had one of mine tripping when there was short in the handlebars. I would actually think the ground is more likely the problem here though. The turn signal module flashing is dependent upon the resistance which is why those doing LED conversions need to add a resistor (Unless the conversion has it already) For it to flash it needs to have enough resistance to do so. Since you don't have any rear lights it indicates that there is likely a ground problem back there since most other issues would only effect part of the rear lighting. As for one signal working up front that particular signal may actually have a corroded connection that adds enough resistance on that side to make it flash even though the rear one isn't. I.E. The one flashing may actually be an indication of more attention being needed on that side once the issue with the rear is solved. If the rest of the system was working properly then neither front signal should flash if the rear ones fail to work as you have stated. Anyway double check those connections and get an ohmmeter and make sure the ground is good to the back. If you can;t find it there then look for open shorts in the wiring. Also find out where those circuit breakers are and listen closely to them to see if you can hear them tripping and then reseting. They make enough noise when they do that you should be able to hear them.

You may have broken a wire under the fender when you removed the sissy bar. I've done that. You need both front and back lights working to make them blink. The TSM senses load, it stays lit when a bulb is not working to indicate a problem with one of the bulbs.
