Electrical problems with my Vulcan 500
Been lurking in the forum for awhile, decided to make an account to post a couple questions I have about my 2009 Vulcan 500.
A little backstory:
I purchased this used as my first bike about a year and a half ago. Up until 3 months ago it was running great. Then my battery started dying. Being the inexperienced rider that I was, I jumped it off of a running car the a few times (found out later the car is supposed to be off) before replacing the battery. Fast forward a couple months, and I started having some problems. It would shut off randomly, it would lurch, and sputter, and after a few days of riding like that I finally had a couple days off to look at it. Tested the Regulator/Rectifier, tested the stator, checked all the fuses in the main fuse box, and then FINALLY found the main fuse in the side compartment and thought I solved the issue. I am guessing after jumping the bike on running cars, that I blew the main fuse.
Now I get to my first question. after searching through as much of the electrical as I could, I discovered that the bikes radiator fan doesn't appear to be connected (see attached pictures.) I found the same color wires coming from the fan, as I found loose plugs in both the headlight wiring, as well as the wiring under the seat. This would explain why my temp light comes on after 5 minutes of idling at a stop light in 80 degrees. Any idea why this wouldn't be connected? After riding it again, I looked under the bike and confirmed the fan is not spinning.
Next up, yesterday as I was riding, it started doing the same thing as it was when the fuse was blown. Lurching, sputtering, backfiring, losing all power, and usually I would only get a click when I would try to start the ignition. Every time I pulled off the seat and tried again, it would fire right up. Could it be a short in a wire? a bad connection to the battery? I noticed the positive terminal connection was a little loose, so I tried to tighten it. I will have to ride to work in the morning, so hopefully that is the problem, but is there anything else you all can think of?
Thanks everyone for your help, this forum has been extremely valuable thus far, and I am sure it will continue to be in the future.
