GL1200A electronic cruise control
« on: August 12, 2018, 07:21:53 PM »
The 1985 GL1200A Goldwing did not come with electronic cruise control.  I have a throttle lock on my CB550F but wanted a real cruise control for the GL1200A.

I ordered the CCS100 from Murphy Kits. I also the brake relay because I plan on replacing the brake lights with LED and got the vacuum reservoir as well.  First step was finding a place for the vacuum reservoir, the place selected was behind the volume controls on the left side of the bike. 

I have not attempted to sync the carbs on this bike so it took a little while to find the vacuum screw. The kit did not include the fitting so I had to use one from the carb sync kit.

Placing the servo took quite a few of on and offs. The cable was a foot longer than needed so the challenge was finding the best route. The horn was removed and the tab on the bike bent so the horn could be moved towards the center of the bike. The cable was threaded between the radiator hose and engine to keep it from getting into the fan.

Getting the linkage attached involved removing the linkage arm on the left bank of carbs, sliding the loop down the arm and over the pivot point for the arm. With the wire loop in place the cutting bending and drilling for the servo linkage could begin.

With the mechanical done, I could move on to the electrical. First order of business was figuring out where I wanted the controller. I chose above the trip computer. This did require a bit of 3d printing to form a back support. The support is attached with screws from inside.

The electrical connections to the bike had a few head scratches. The red and violet wires for the brakes, I ended up attaching to the relay by the bars. For speed indication, I attached the blue wire to the right coil. Power and grounds are attached to the accessory post.  4 delco vacuum check valves were added, one to each carb and tubes T fitted together. 
I had to change the side of the coil that I was getting signal from for the controller to work.  One advantage of using engine rpm is that you can test the cruise in neutral.

It took several months of on off troubleshooting to figure out the proper wiring for the speed input.  Not that it is done the cruise does work nicely.  Because of the manual transmission I found it did a good job of keeping the bike at posted speed on a long hill that is steep enough to have a runaway truck ramp.

Hopes this helps someone else.
