I have an '07 Ultra. The cruise has gotten where it won't always set and if it does and I hit a bump, it kicks off. I unhooked the roll-off connections (the connectors that connect to the throttle cable) and it works fine. Is this a bad module or in the throttle cable itself?

 

Try checking out both of your brake switches.

Set the cruise and see how little pressure is required to cancel cruise control. I bet you might just find one of them overly sensitive.

On my RK I found that the front brake handle was sensitive like that.

Hope that helps!!!

 

You might try to re-set the cruise lash.

 

I had the same problem and it was the brake switch.

 

I don't mean to hijack this but, I've also had a problem with cruise control cutting out intermittently. The 'cruise light' stays lit (green) as if it's still engaged. No bumps on the road which could contribute to loose wire problems. I can disengage by hittin the brake and the green light goes out. So.....my question to AlleyKatt is >>>>> Does the 'indicator' light say that you're still in 'cruise'?

 

Here's a procedure you can try.
It works on an '05 FLH so let's see if it works on your 07'.

1. Hold cruise switch in the "set" position.
2. Turn the cruise "on"
3. Turn the main power switch on, the cruise light should initially come on then turn green, release the cruise switch the light will turn amber.
4. Push the cruise switch to "resume" the light should turn green, release the switch, the light should turn amber.
5. Roll the throttle "off", make sure you roll it off to activate the cutoff switch for the cruise, the light should turn green, release the throttle the light should turn amber.
6. Apply the front brake, the light should turn green, release it, the light should turn amber.
7. Apply the back brake, the light should turn green, hold the brake until the light turns amber, release the brake now, you should hear the cruise motor adjusting itself (taking up the slack).

What you have done is test each of the "switches" that are in the cruise system. If, during any of the tests, the light does not turn green, then that part is at fault.

The back brake switch is often at fault. You can test that by applying the brake and see if the light is already on. If it is, the cruise will not engage.

The front brake switch can be at fault also, as it sometimes gets damaged when work is done on the right handgrip/brake lever assembly and the proper procedure is not followed.

The "roll-off" switch can also be at fault. Check the connections on that.

 

the rolloff module may be bad but more likley theres some stretch in the roll off cable, might be able to get it with some adjustment.

 

Thanks, I will check it.

robvg: No the green light goes off when the cruise disengages.

 

I get that whenever the shop does a 5,000 mile service, and they set the throttle cable too tight. Not enough lash to compensate for small movement of the cable by the cruise mechanism. When the tension gets too high, the cruise control will disengage.
