The most common problem on the 1500 cruise is the clutch switch. You should be able to hear it click when the lever is moved in the outer 1/2 inch of travel. If it doesn't click, or if you have to push the lever out manually for it to click, remove the lever and clean the switch push pin with contact cleaner. Also, many riders do not lube the lever pivot bolt and it could be binding, preventing it from releasing the switch. Both clutch and brake lever pivot bolts should be lubed with a little white grease annually. If cleaning and lube does not cure the problem, The switch could be worn. Stick a shim on the lever where it contacts the switch.
