Default 2004 Road King Cruise Stopped Working-HELP

The green cruise light comes on when you set it but doesn’t engage the cruise, any help would be greatly appreciated. I have looked through the threads here and haven’t found one like this.

I had that happen on my 2002 and figured out that the harness under my seat was pinched and it wore through one wire and it was erratic when hitting bumps etc. It wasnt blowing any fuses but that one wire was somehow affecting the cruise engagement. It was years ago, so I dont remember what wire it was, but I think it was related to the brake circuit. (Im guessing thats one of the signals that disengages the cruise when its on) Anyway, I fixed the wire with heat shrink and correctly routed the harness and it hasn’t happened since. I only found it by accident when I was changing the battery and inspecting the wiring.

Is the green light staying on when you set it and the bike just going to idle when you take pressure off the throttle? If so, your stepper motor may have gone bad or the ribbon/cable came undone or has broken.

If the green light turns red right away, I would unplug the idle cable sensor or check your brake light switch.

Ok, so everything is in the correct conditions; >=3rd Gear, >30mph. The green light means its trying to hold your speed. So I would rule out wiring. I would pop off the left side cover and inspect the module.
There's the module (black box) that has the circuit board, stepper motor, and ribbon.
Then attached to it is the ribbon to cable adapter and cable running to the throttle.
I would look to see if the cable is still connected to your throttle body. There's a plastic clip that attaches the cable to the throttle could have weakened after 17 years and broke.
If that looks good, I would inspect the ribbon adapter. I think there were some reports on the ribbon breaking.
If all that looks good, i would say the stepper motor is bad or the module itself is bad and would have to replace.
If you change modules or mess with the ribbon, I would make sure to do the cruise control ribbon cable adjustment procedure.

cruise-control-initialization-diagnostics-and-codes

I took the procedure from the link above that matches my service manual.

The engine should be at normal operating temperature and throttle and idle cables should be correctly adjusted. To set the correct cable lash proceed as follows:

1. Push the Cruise Switch on the right handlebar to RESUME and hold it.
2. Turn the Cruise ON/OFF switch to ON.
3. Turn the Ignition switch to IGNITION.
4. Start the engine. The green Cruise Enabled/Engaged lamp in the speedometer will illuminate.
Wait 3 Seconds for the lamp to go off.
5. Release the Cruise Switch from the RESUME position
6. Push the Cruise switch to RESUME and hold. Cruise will pull in cable until change in RPM is detected. The number of motor steps required to rev the engine is stored in memory.
7. After engine revs and Cruise Enabled/Engaged lamp is extginguished release the Cruise Switch from the RESUME position.
8 Turn the ignition switch to off.

Hotbikeweb - Cruise control install 70955-04

Here's link of Hot installing a kit but should help you see where the cables run on the throttle. There could be a chance a retaining clip fell off as well.

Check your throttle cables. There is a rolloff switch in one of them. You need a little slack between the two cables. I took the slack out of mine and lost cruise. Re -slacked and it's fine..

I was actually expecting to read something along the lines of: they all do that.
There is certainly a wealth of useful and very generous helpful information on this forum.
