Stumped with electrical problem
This is my first post here, so forgive me if I am breaking some sort of forum rule. Anyways I have a (new to me) 2002 Vulcan I named Roxanne. I love her, but she's giving me a lot of problems. I'm pretty good with my hands, but electricity scares the hell out of me. Anyways here's my problem: I will ride somewhere and she'll be running fine the whole time. But if I make a quick stop where I kill me engine (getting gas, going to a store, talking to someone) she won't start back up. The panel will light up, but when I press the start button she doesn't turn over. It bugs the hell out of me. The only solution I have found is waiting. After about 5 or 10 minutes, she'll get running again. I'm pretty certain that the issue lies in my battery (it hasn't been changed, ever), but I fear I could be wrong. Talking to some of my buddies made me more scared. They said it could be my voltage regulator, or my stator (I have no idea what these are). What do you guys think?
Also, if it helps diagnose, I have her on a battery tender right now. The other day she had the issue where I would have the bulb on my tender be green (signifying that the battery is charged), but when I turned her on and press start I would just hear a "CLICK!" to the back right of me, and the battery would die. The problem happened only once, and went away, but it was also concerning to me. The main issue I have been having was with her dying after riding. She usually starts right up in the morning.
Anyways sorry for the long post, and thanks for the help.
