I have a 2003 Screamin Eagle Roadking and the crusie control has quit working, I tried another cruise control module but still no fix, anyone have any ideas or is there a know problem area I need to check out? Any help is greatly appreciated, By the way I am new to this site and I am very impressed with the amount of knowledgethe members here have. Thanks C.H.

 

Great timing. My '03 RKC just died yesterday--at the Myrtle Beach Bike Week--565 miles from home with the local dealer not having ANY appointment--until late next week. I called Wilmington,NC and spoke to Kris who suggested that I check the fuse (no luck) and the spade connectors on the throttle release (two spade connectors on the frame just in front of the fuel tank (no luck). Could be the brake light switches (front or rear) or a ground that's shorting the electricalal system, spoofing a "brake light activation. Good luck. Riding home Wednesday--hope someone else has a better suggestion...

 

Hope you had a great time at the beach, I have tried about everything on mine with no luck, I went to the HD dealer and the parts guy made a copy of the cruise part of a repair manual but it doesnt really help at all. I was wanting to know what the resistance was suppose to be on the throttle rolloff switch but no one seems to know, on mine theres no contunuity at all, Hell I know there should be some, when I move it I get an ohlm reading, that tells me that somethings got to be wrong with it or at least I hope so, anyway I ordered a new cable assembly, and I am keeping my fingers crossed. If anyone knows what the resistance should be please let me know. Thanks C.H.

 

I found the problem with my cruise, the throttle rolloff switch thats located in the throttle return cable was bad, its a simple little switch when working properly it will have 12 volts on one terminal and when you twist the throttle towards the idle mode it squeezes and makes contact, if you have 12 volts on both wires at idle yours may be bad too. I would unplug one side of it and go ride if the cruise works you have found your problem too. Happy cruising C.H.

To expand on that; your throttle could just be out of adjustment enough to mess with the roll-off switch. Too much or not enough play can effect it.

 

Did you change to a LED type tail light? They don't draw enough current to allow setting.
