Starter stays engaged - 2005 Yamaha V Star 1100 Classic

you have a short in the system get a multi meter to test circuit

inhibit relay

starter button on handlebar could be bad or stuck.

Either the solenoid is getting power when it should not be, or the starter drive is not aligned with the flywheel.

Sounds like time for a new starter. While it could be electrical, in that the starter circuit is remaining engaged, more than likely it is mechanical. As the starter wears, you get play in the starter gear. Replacing the starter should take care of it. If you have recently had the starter off or replaced it, it could be misaligned, causing a similar problem.

2 problems, first you have bad starter or starter relay for starter staying engaged, keep alt plugged in has nothing to do with starter staying engauged, to test starter relay, jump at relay bat + post with red/bk wire on solonoid, if cranks over without staying engaged, then not relay or starter but rather in your ign switch, ford had bad problems with ign switch some years ago doing that

The starter solenoid is stuck. Replace it.

solenoid on starter is sticking and needs to be replaced or repaired

Replace the starter,that`s the only way to fix the problem.

I would check the starter clutch its self first. It is a one way clutch so if you remove the starter and disassemble it to the starter clutch and hold the starter clutch in one hand and use your other hand to turn the starter clutch gear, it should only turn in one direction.
