I would say he has the switch and it's not working. My bike was performing similarly with a known broken switch that I broke while changing grips. You can look under the clutch lever flange where it covers the back of the switch housing and see the button on top of the switch, unless it's been broken off like mine. The button is surrounded by a rubber material to help seal the hole in the switch housing. I was also getting security system light constant on while running and error b1154 (clutch interlock shorted to ground). With the bike switched off, the security system light returned to normal periodic flash.

Again, there's a similar switch under the front brake lever as well for the brake light.

Yeah, good point. I'm not familiar with all of the interfaces involved with a bike cruise but assumed the clutch lever would be a candidate for sure; like a car. I was wondering whether it was a normally open or closed switch. I didn't check continuity it before I put my new one in.

Well thanks mswing. Your original post didn't grow any legs, but this is useful information.

The only issues with not having the switch operational were not being able to start the bike in gear with the clutch lever pulled in and the annoyance of staring at the red security light (error) while riding. Anyway, the replacement was fairly easy. Move the clutch lever (this time) and open the switch housing. Cut out the old switch, install the new one, splice/solder the wires, heat shrink, and close up (carefully). Clear error b1154. Good to go.

Sounds like this was a fairly easy repair? The wife's Softail Custom has a bad switch, yes it is a PIA issue when it doesn't work.

Yes, the repair is easy if you have a little skill with a soldering iron, heat shrink the exposed wire, and be careful not to pinch any wires when you put the switch housing back together.
