I had the same problem. Mine was simple to figure out. To put it bluntly your cruise will not engage if it think the brakes are on.

I am guessing if you checked you might notice that your brake lights are always on. That was the case on mine thus I experienced the exact problem you are finding. I found that I could push the front brake lever forward a little bit and brake lights would go off thus cruise could engage.

I thought it was an issue inside the brake lever since it wasn't releasing all the way. Come to find out it was the master cylinder that was the issue. I had a rebuilt master cylinder put on and all was good.

Hope that helps.

 

So did u figure out the problem Terra? The suspense is killing me!!

 

Well, after much reading, watching the response from this fine group and checking all the connections to make sure all was as it should be I finally found the problem. Sometimes the solutions are quite easy if one will only read the instructions. The reason the cruise control would not engage on my bike was simple. After re-reading the electrical repair manual it stated; to engage the cruise control one must be in 4th, 5th or 6th gear and be moving at least 30 mph and not be exceeding 85 mph. In my case, I was trying to engage the CC in 3rd gear will trying to adjust something on the bike, I can't remember what. So, the moral of the story is simple; WHEN ALL ELSE FAILS, READ THE INSTRUCTIONS.
I feel like a dummy.

 

Glad you figured out the issue & no worries - we've all been there. Men never read instructions...

 

My 2009 street glide went out to. Harley fixed under a recall, take less then 30mins for them to install.

 

the cruise on my bike works in 3rd gear. i know, i use it all the time to keep at 35 on post. them mps can be hell

 

Don't know what to say other than the manual for my 09 UC clearly states you must be in at least 4th gear and traveling at least 30 MPH. Section # 4.27 \ DTC PO 577. Maybe your model is different. I know one thing for sure, my CC will not engage in 3rd gear at or above 30 mph. That's a fact Jake!!

 

huh, thats weird. i checked my 2007 manual, 2010 manual, and 2012 manual. none of them mention anything about having to be in 4th gear. they do mention that you have to be traveling over 30 mph and less than 85 mph....

 

Use my CC all the time and can verify, must be 30mph or above, and in 3rd gear or above

 

Exactly the same scenario with my 09 BargeGlide.

I'd be checking the brake light to see if it was "on" if I was Terrabella (OP).

EDIT ADD: I hate it when I don't read all of the posts before posting--- good to read your back on deck Terra
