Hi everyone and greetings from the UK!
After reading various posts all over the internet, including here, I decided to go ahead and fit a Rostra Cruise Control for my trip to Italy in 5 weeks. I imported the kit from Kartronix in the US via ebay.
I followed various guides from here, Murphs Kits, and Youtube, and the install seemed to go ok. I set the DIP switches, and carried out the diagnostic tests, which all passed - great!
I took the bike out and rode at various speeds, but no matter what I did, the cruise control just would not set and engage. I have the rocker style control switch with the ''on'' and ''set'' LED's. The set LED will not light up, so its acting as if the CC is not engaging, therefore not sending a set signal back to the control switch LED via the orange wire through a relay.
I have a feeling that the Rostra is faulty, but if anyone has had a similar experience and knows a solution then I'd really appreciate some advice.
Cheers everyone,
Mark
One important thing to go back and check is how the brake relay was wired, and that you got the proper relay! There are 2 different types of relays- N/O & N/C... They both look identical, numbering of the posts and all. You must use a normally closed type relay.
Usually, the number one cause for the Rostra not engaging is the unit DOES NOT SEE GROUND.
Ya might check that, and check that the relay clicks when either brake is applied.
If it does, then confirm with a 12V tester that the relay is opening the ground when the brake is applied.
Ground loop through the relay should be closed until the brakes are applied, then it opens, and Rostra stops working and disengages.
If you have the type of switch that has both the power on and the "ENGAGED" light, it requires the same normally closed relay installed in that circuit as well.
If it passes diagnostic, but refuses to engage, this may be your problem.
HTH's, good luck! You will LOVE the Rostra on long trips when you get it going!
Can't take a long trip w/o mine!

No problem Bro...
But I just went through this with my friend Tim's CC install.
I advised him to get his relay from Murph, but he instead bought one off of Ebay.
Looked right, numbered right... Worked exactly backward.
Started checking around locally... Everywhere. They all sold a N/O relay. When energized, it would close... Azz backwards.
Ordered the one from Murph that is the part number you list in your tutorial. Unenergized, it's closed. Energized it opens.
They look the same, but work the opposite.
That's just been my experience recently.
Let me also say, I never even thought about that until this happened! It delayed us 3 days from finishing his install, but thanks to Murph's fast response (as always!) we got it going.
With that said, I'll end with this... I never want to post anything that would mislead someone.
Not my intention...ever. But after 8 of these installs now, the Rostra NOT seeing ground has been a reoccurring issue if it doesn't work.
Just thought I'd throw that out there to him, since I ran into that situation recently.
But, I bow to your superior intellect, sir! When it comes to the Rostra, you be da man!
Working on it...

Brian is not kidding about the "lots and lots of questions", and they constitute a large number of separate threads. Threads of related interest that people should also examine include (but not limited to):
<snip>
What we probably need is an incorporated wiki page that consolidates a lot of that valuable info into one place. If that doesn't work, I can always keep this thread "clean" by moving out any posts not by you, so you can keep this as the go-to/summary thread (if you want to do that, just let me know).
I would have to say no. I believe that the speed sensor need to have a signal sent to it, so the wheels need to be turning. Brian will be able to confirm or deny my minimal knowledge on this.
Ok thanks for the reply Nicole, I'll go and test the bike shortly.
Just carried out some checks again and all the diagnostic checks pass. It is wired as follows -
Red/Brown - Goes 12v positive when the "on" control switch is pressed.
Violet - Negative from Brake relay, switches 12v positive when brake is pulled.
Black - Negative
Yellow - Switches 12v positive when the "R/A" button is held down on switch assembly.
Brown - 12v Positive from ignition switch.
Grey - 5v square wave from Vss sensor.
Dark Green - Switches 12v positive when the "S/C" button is held down on switch assembly.
Dark Blue - Connected to ground (negative).
Light Green - I have this disconnected at the moment until I can get the CC working.
Orange - Connected to a relay coil to drive the "set" LED.
Switches set as follows -
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
off off on on on on off off off on off off
I'll report back soon with the results of the test ride
There have been lots and lots of questions / problems during the installation of Rostra cruise control units on C-14's, and occasionally operational failures after the units are installed and working correctly. I thought I would start a thread about that very subject so that perhaps we can keep the Q&A sessions in one thread that anyone can reference in the future.
The question from another thread that got me thinking about creating this thread was: "As far as the CC goes, I havent had a chance to get into it yet. I was wondering about the switch as well. When I did the install, I was very thorough with sealing it up. I removes the silicone key pad from the cover and used silicone to seal it to the cover. Then once all was back together I sealed up the backside. Question.... I am getting a power light on the keypad as well as the engage light. So would this eliminate switch problems and also eliminate fuse problems?"
If a Rostra cruise control is used with an 'Engaged' light, and that light is being lit when the SET button is pressed, it means that all electrical connections throughout the bike are working correctly, including the switch. If the 'Engaged' light is lit and the cruise will NOT take over the throttle, it is a mechanical problem, most likely at the cable to throttle arm connection but possibly inside the Rostra actuator itself (although I have not heard of or seen this type of failure).
