Well, after hours of toiling over the K1's new cruise control mod, it's all working and i can now give my bum shoulder (basketball injury) a rest from now on during long rides. It's a remarkable modification to the K bike. Frankenduck created a helluva modification for the K bike using the windscreen switch. i highly recommend it for the untimid installer.
A gigantic heartfelt THANK YOU shout out to Frankenduck for his unwavering support of my effort to get this installed.
For the next guy who installs the cruise control on his K bike, i learned the following:
* Wiring to the correct wire on the coil. Double, triple check that you've connected to the right wire. Without the connection to the correct wire, the servo won't engage. All other connections problems, if you have them, mean nothing until you know the servo will work. It won't work without the right coil wire being connected. And, you can't see an LED response on the servo from the coil wire connection, so check and verify.
* If you have issues, test each connection with your meter 10 times, and write the values down.
* Don't bother test riding the bike until ALL wires check out, and any residual voltage in the brake circuit (purple wire) is kept to a minimum.
* Follow FDs instructions, but also print out the manual on the sellers site for the cruise control unit. The instructions for the unit contains specifics for how to test each wire for the servo, and are very detailed / helpful. Not all of the seller's instructions are applicable for a bike install, but pairing FDs instructions with the manual for the cruise control will yield better results.
* The install cannot be done correctly without a voltmeter / multimeter. You may get lucky without one, but Murphy's law will catch up to you on this one. There are just too many things that can go wrong on this install.
* Posi-taps / Posi-locks are great. Buy many of them.
* It's not a quick install, and it's not plug-n-play. Expect to put some time into it.
Hope the above is helpful to any future installers.
