I have a 99 1500 Vulcan Classic, it has been sitting in the garage for about two months. I attempted to start it a couple days ago, turned on the switch and got no power to anything at all, starter, lights horn. I removed the seat and checked all the fuses, all good, battery fully charged. I pulled the tank and cheked all connections, all good. I have no idea what to check next, so any help I can get will help alot.

I have a 1997 Vulcan 1500 classic and had a similar problem. Mine turned out to be a bad solder joint inside the key switch. Re-soldered it and it's been good ever since. Wasn't a bad job just be careful when disassembling the switch if you need to as there are small springs inside which may become lost if you're not careful.

Tim,
Keep us posted on this one. If it's not a fuse it would appear that it would have to be in the ignitions switch somewhere as Comet mentioned. There aren't many components that will knock out the whole bike's power supply.

Ive got a 2002 classic and that happened to mine just after I got it. I found that the 30amp fuse on the right side under the side cover had blown. Dont forget to check that fuse also.

It is a better plan to troubleshoot the issue rather than just taking things apart looking for the fault. There is always the chance of introducing another problem and then the real tail chasing begins.

If the fuse does not get you going, post back.

Well the fuses are all OK. Bike still has no power to anything. I do not understand how just sitting in the garage something just gave up the ghost.

Ensure that battery connections are clean and tight (not gut-busting tight).

If no joy there, do you have a meter and know how to use it?

No meter, we can help there too.

When you check the fuses...test both sides with your meter...don't just look at them...check your wiring diagram for the power wire that come off the battery...it has 12 volts at all time and should provide power to your solenoid...on my old 1500A 88 model I think it was a solid white wire...while your at it...check your ground connection...I always add a good ground wire from the negative battery post and run it to frame...after I removed all paint and its nice and clean bare metal...I have been doing this for more than 40 yrs...I ground all my electrical to frame...If something has a ground to it...run it to frame with a little dab of electrical grease...really keeps the electrical gremlins in check...your lights will be brighter...it will start a little better...spark at the plugs a little bluer...less strain on your R/R...good luck

Pretty old thread with not-too-active members. I think they were referring to a resistor and not a "diode".
I found some information online when searching for "Vulcan 1500 resistor in ignition switch"

Did you see this?

Diode - Vulcan Bagger Forums


I'm having the same problem. Can you post a picture of diode to help me out

If the 100 ohm resister at the ignition switch was bad or removed, it still would not prevent power from going to the ignition and lights. It just reduces voltage to the igniter to turn it on. If you have no power when the switch is turned on, start by checking voltage on the white wire at the switch, should be battery voltage.
