Just traded for this 1993 sportster. It has some serious issues trying to figure out some electrical issues.
The black wire is not hooked to anything. Any ideas? I know this is a ground but I cant figure out where its grounded. This was all taped up Is this anything to do with this bike? It was stuck by the battery and not hooked to anything.
The last lead is an add on. It is for connecting a battery tender. A good device for bikes that have electronics always drawing power. For your bike I suspect it is not actually required if you ride reasonably frequently and far enough to put back what starting the engine draws from the battery.
There should be a ground stud behind the starter, your 1993 should be very similar to my 1991. The taped up thing looks like a circuit breaker, and that box thing has something to do with your signals, as violet and brown are the stock colors. I think your turn signal module has a few more wires, so that may be some kind of load equalizer. My turn signal canceller has 7 wires according to my FSM.
This should help, it a color wiring diagram for 1991-1993 Sportsters. From XL Forum.net, but I saved it to my files for use. You need a microscope to read the wiring diagram in my FSM, this is much easier, scroll down to post #4. Good luck. http://xlforum.net/forums/showthread.php?t=2074661

Yes... aftermarket signal Module with Brown and Purple wire, Yes Aftermarket Tender lead on bottom.. with pipe hiding other end of battery wire... I ain't guessing if Battery + to starter motor, or ground lead to Battery -
That Circuit Breaker has been abused some... and I do Not remember them floating around loose..
Actually, looking at that picture of the taped up breaker, that is your main circuit breaker, and it's supposed to be attached to the fender under the seat. Hard to get to, but you don't want those red wires grounding or you'll have one hell of a lightning show.

Bike looks good! 29 years is a long time, bike years can be longer than dog years. My bike has been indoors or garaged since new and some metal parts look beat due to the ocean air where I live. Yours looks pretty clean to me. A bit dusty, but, aren't we all?
I see you have a chromed primary cover with the hole style adjuster. Mine was upgraded to chrome after a crash, but it was the '94 style cover with the larger derby cover and 4 screws. I think the newer style allows cable and throwout bearing changes without removing the whole cover.
