Hello, My name is ***** ***** I am here to help you with your Vulcan. I am sorry to hear you're having a problem with it but lets see what we can do.

Please ignore any automated phone call requests at this time (unless so desired), I will let you know if we have to go that far.

It sounds like you have a bad starter solenoid, or, in less likely case a shorted wiring

You can remove the solenoid and bench test it, or check for continuity between the starter motor and battery posts on the solenoid with the battery off the bike. If there is no resistance (and full continuity) between the posts - its the bad solenoid.

Let me know if you need help on going through with it

I got a tester do I switch it to ohms side or ac
Starter looks like it's in front of bike under radiator

Dear customer,

Thank you for your response.

You can set the voltmeter to OHM setting for continuity test. The starter solenoid (aka starter relay) is located under the seat, it also holds a main fuse in it (see pic). There are 2 larger gauge wires coming into it, one from the battery and one all the way from starter motor. We need to check the continuity between those two wires.

Let me know how that goes,


Ok thanks

Dear Customer,

I hope you found my answer helpful,

Please feel free to contact me if you have any additional or follow-up questions, I would be glad to help

All the best,
