Is it the belt switch or the underseat switch that is bad? They are interconnected, underseat has to make contact for the belt to work. The under seat one is cheap but the belt is a couple hundred. Nevertheless do it right, couple hundred wont buy much flowers at a funeral this time of year if things go wrong. Look at the new Holland forum and there should be more info. Mike10 explained the sequence at least once so look at his past posts. I am surprised you can use the boom if the belt switch is bad because it is involved in unlocking the boom solenoids.
