2015 road king cruise control won't engage but all the switches from a diagnostic test work, rear and front brake switch good, throttle sensor good, clutch good. I have no clue which direction to go at this time, any help would be greatly appreciated

 

Welcome aboard from Old Cape Cod!!

Factory Service Manual has the diagnostic instructions.

 

Will the bike start in gear with the clutch pulled in?
If it doesn't and only start in neutral probably left switch pack.
(No cruise, no start in gear with clutch pulled and or no gear indicator = left switch pack faulty)

 

gonna go give that a shot now thanks

 

It does not start in gear with the clutch pulled in

 

Clutch switch in the left switch pack is bad. Can try cleaning it

 

Same happened to me a few years ago but mine was covered under warranty.
Some had success cleaning with wd40.
Or if you ever wanted lighted switch packs you have a good reason to get them.
