Cruise Control glitch

[Biggles]

The MCC device is really very well designed and built.
It's only let me down once, and that was when corrugated dirt road shook the wires off the spade terminals on the pick-up.
However, yesterday towards the end of a 780 km round trip it refused to engage.  It showed the red LED then the yellow, but wasn't controlling the speed.
So this arvo I pulled out the excellent Troubleshooting booklet and worked through the checks. 
Engage- checked
Brake- checked
Clutch- checked  (remember on the STs you need the sidestand up and the bike in gear because they're in the clutch/ignition circuit)
Rev up- failed   

Next check was to focus on the actuator system which I wasn't relishing at all.  However I decided to pull the 24 pin plug just for the exercise and pushed it back on and walla!  The controller worked.

It hadn't been disturbed for 2.5 years and obviously one of the contacts had become resistant.  Another thing to be aware of!  These low amperage electronic circuits aren't idea for bikes, even when they're as well protected as they are in the tail area.

Took Ruby for a celebratory spin and she sang her automated song for me.
We're back in love.

Well done Biggles.

I have recently installed a McCruise and decided to use the '1300's speed pulse sensor to avoid any problems (rare they may be) with the pickup on the axle/swing arm.

It was an easy install and recalibrating the controller for the change in pulse was easy, only taking one steady run on the bike at 70kph. Works great . .  Just need to go do some riding . .

The bike's pulse sensor must be a more recent innovation.  Sounds like it beats the magnetic pick-up system which is also vulnerable to gap sensitivity.

I think all 1300's have the speed sensor (mine is a 2008 model) it is just a bit more difficult to get to but really only requires taking off the right hand side cowl, then exposing the group of plugs and choosing the right one. Might be worth checking with the McCruise fellows as to whether your McCruise can be re-calibrated to use the speed sensor . . . I think they have changed the control box in recent times but not sure exactly when.
