07 FLHTCU Cruise Question
I recently installed Yaffe monkey bars with internal wiring.
After final assembly I checked operation of all the handlebar switches.
I checked the cruise with the diagnostic procedure (hold cruise set button to right, turn on ignition, check that each switch turns the orange cruise light green). All switched functioned properly IF they were tested in a specific sequence:
Set switch,
Resume switch,
Throttle Roll Off switch,
Front/Rear Brake switch.
I have checked the roll off switch and brake switch with an ohm meter and they function properly.
I have the bike on a lift. I started the bike, shifted into 5th gear and ran the speedometer up to 40mph, then applied the cruise. The light turned green, cruise engages for a second, then disengages, and the light turns orange. All other switches on the handlebars operate properly.
I'm in Michigan and cant actually road test this issue. I would like to make sure the cruise is working before riding season gets here.
I said all that to ask this:
Does the cruise test procedure need to be done in this specific order to verify proper operation of the switches?
Should the cruise engage when the bike is on a stand? Is there another sensor or parameter that must be met that I am not thinking of?
Thanks,
Slang

See if your brake light is always on. After changing bars my cruise would not work and thanks to another thread on this forum I found out that was my problem. Brake lever was not depressing the switch enough to disconnect brake light.

The problem might be the way you're testing. On the 3 bikes I've had with cruise control, if you're running down the road with the cruise on and hit a big enough bump, the cruise will disengage. I think this has to do with the fact that as the rear tire looses contact with the road, the RPMs will increase. That triggers the cruise to shut down. Sometimes it doesn't take much of a bump and I haven't even noticed an increase in RPMs. I would think the cruise would work on a dyno but I'm not so sure about when the rear wheel is just spinning freely.
3. Motorcycle clutch is disengaged (module senses too great an increase in RPM).

My experience with the CC is that if a brake switch is st fault you cannot get the CC to engage (green light) at all. A defective or misadjusted roll off switch can cause all sorts of unexplained CC cancellaions. My 07 would have the CC cancel pulling up a hill without speed or rpm loss due to that switch. I now just leave it disconnected.

Guys,
Thanks for the replies.
I have ohm'ed the brake light switch and the roll off switch. Both function properly. I will disconnect them and see if the cruise stays engaged.
I will do some more testing on the stand. At this point, I am not 100% sure I even have a problem. It would be so much easier if I could just road test it. Damn these Michigan winters.
Thank you.
