Welcome. Thank you for choosing Just Answer.


do the brake lights work?


have the throttle cables been adjusted or replaced?


are you having any problems with the speedo or tach?



Customer: replied 6 years ago.
brake lights do work cables have not been adjusted , to the best of my knowledge, speedo and tach work fine

you can try disconnecting the wires from the throttle roll-off switch.

see if it engages then.


if not, you likely have a problem with the interconnecting wiring between the cruise unit and the bike. it could be anything from a loose pin connector to a pinched wire or a bad ground. you should look at the things that turn the cruise off.........throttle roll-off switch, brake relay, speedo and tach.


let me know what you find and if you need more help.


Customer: replied 6 years ago.
can you breifly tell me where the throttle roll off switch is located and does anything have to be taken off of bike to get to it???

no problem.

it is on the right side of the frame, just forward of the fuel tank.

all you will see is a fat spot on the idle cable with 2 wires attached with spade connectors.

all you have to do is pull the wire terminals off the switch.

if this is the cause of your problem, it would indicate either a bad switch or, typically, indicate the need for a throttle/idle cable adjustment.

there is a special procedure for these cables.

it does require a volt-ohm meter for the adjustment.


let me know if you need more help.
