Electrical issue

I have an odd electrical issue. My 200 Vulcan 750 has 4500 miles. Last year I replaced the battery with a westco battery. The bike is always on a battery tender. The first time I took it out this year it ran great. I parked it at work and when I came out to start it the battery was DEAD. Had to push start the bike. After charging the battery and taking for another ride I noticed that when the igntion was off (key out of bike) the rear taillight was glowing. Now, everytime I take her out if I shut it off the bike is comnpletly dead (sometimes you still see the taillight glowing)

Soundls like a short ssomewhere to me. Any thoughts?

I know I sound like a broken record sometimes from other post, but do you have a manual with a set of schematics? It would be a lot easier to see how it's suppose to work and when someone try's to explaine it you can follow what there saying. For me I wouldn't even start with out a schematic.

short in the ignition switch maybe, or a bad junction box.. it has to be one or the other. those are the only two places that something could short out and back feed through the electrical system to the tail light.

unplug the ignition switch and see if you are getting power to the Brown/White wire. (you shouldn't be).

I know you said tail light....but I just want to be sure you were not seeing the brake light stick on.
Brake light staying on could be a stuck switch from either the hand or foot brake switch.

I agree with Slim, but think it might also be worth taking a peek under the seat and see if any wires are pinched and possibly shorting when the seat is being compressed down. there is a harness with a 3 wire connector for the tail light and license bulb. It could be possible that something in that area is shorting or back feeding into the tail light if the wiring is frayed.

Good luck! let us know what you find.

When you turn the ignition switch off, it is supposed to cut all electrical collections. So your brake light won't be lit as well as your tail lights. If you have a stuck light switch, the brake light will go out when you turn off the ignition switch.
It's possible that you have a short in your ignition switch. As they said, unhook your ignition switch check to see if any lights stay on.
