Looked around and not sure if I have put this thread in the right category . . . will ask a MOD to move it if appropriate.

Bought my 03 SERK with 3700 miles on it . . . cruise control has never worked . . . time to get it working.

When I engage the left control on, the light comes on.  When I to then set the cruise on the right control, no light comes on and it does not engage.

When I changed out the handlebars last week, I looked closely at the wires in the right side cruise control . . . all looked good . . . did not see any crud build up etc.

And my brake lights all work as designed . . . none stuck or off . . . no switch problem on them.

I adjusted the throttle and idle cables correctly . . . they seem just right . . . not too loose or too tight.

I took off the left side plate and everything looks connected . . .

So, is there a reset procedure?

Other things to look for in troubleshooting?

I want to try to fix it myself before I take it to the dealer . . . getting ready for some long rides and would like to have the stock cruise working so I can take my right hand of the bar occasionally.

Ideas?

how old are the throttle cables? is the roll-off switch connected ( along the right side of the frame between the front of the tank and the nacelle )?

[Twolanerider]

The switches in the throttle cable won't keep the cruise control from operating.  They could be completely unplugged and cruise would still work.  You'd just lose the roll on/roll off shut off function.  Aside from that there aren't many pieces to the system.

Did you actually check the switches with an ohm meter while you had it all apart?  Just because they're clean doesn't mean they work. 

The stepper cable (the cable from the cruise module to the throttle body) can break.  Not likely but possible.  More commonly they get sticky inside their housing and bind up.  But they're inexpensive and not terribly difficult to change.

You said the brake light was working.  So you know it's not a brake light switch stuck in the on position and keeping the cruise system from working.  If you're sure it's not a switch and you're sure it's not a cable and you're sure the stepper cable is in tact and isn't stuck the only part left is the cruise module itself.

Only other thing I can think of is that on some older models (and I don't remember when this changed) if the brake light was burned out that kept the cruise control system from working.  If that's still the case in 03 the LED brake light might be interpreted by the system as no bulb.  But if cruise didn't work with the prior normal incandescent light bulb that possibility is perhaps eliminated.

many years ago, my cruise would not engage, or would engage very briefly and disengage. the fix was to replace the throttle cables

Not sure why that would be Neal.  You can unplug those switches and cruise still works.  At least on the older stuff like ours.  My last Road King even got new braided cables I swapped something for that weren't for a cruise bike.  So the switches didn't even exist.  Put those cables on the bike just to gain the braided look.  Ran the cruise for at least 40k miles after that.

wonder what the effect of a dead short in that switch could be? guess he could unplug it and try the cruise again.

If you have a Service Manual there is a test procedure to test all the input. Something like holding the SET button when you turn on ignition. Then it uses the cruise light in some manner.

    Rhetor, two other common problems are led tail light bulb and turn signal/brake light module. if you have a led bulb just
replace it witha regular bulb and test . and if you have a t/s/module like most of us do unplug it from the harness under
the seat and don't forget to plug the connector back together with out the module and test drive.       
  good luck,  axil

Had the problem before I added the brightass light . . . and I have just regular red incandesent bulbs in the turn signals.

Throttle cables are stock braided . . . I have 5800 miles on the scoot; had the problem when I picked it up with 3700 miles on it two years ago . . . throttle cables look great all along.

I will have to get the manual out to find the roll off swith . . . where is it?

Just in front of Fuel tank right side. It has a black Plastic sleeve that slides over it. Has 2 wires attached to it.

I have an ohmeter, but can't find the witch yet to check it . . . I will break out the manual in the morning . . . don't know where to find it.

I did pull the left plate off to see the Cruise Control Module .. . . cable is functioning with the throttle body and connected and not kinked. is still attached to the cruise module and the throttle body.

All brake lights are functioning well.  None burned out either.  

So it must be the cruise module itself or the switch?  How do I check those?

Throttle cables seem to be in great shape on this low mileage bike . . roll on and roll off adjusted and working great.

Thanks, Brad, I will find it first thing in the morning and test it.
