[QUOTE="Shanmar, post: 123730, member: 21969"] My experience would say that the two problems are likely unrelated. I've run into the random brake thing before. The EIC needs to see a steady signal from the seat presence switch and the seat belt switch. Here are some things I've seen cause it on my machine with over 6000 hours on it. - bad seat belt switch (maybe you can operate it and jiggle it and see if you can make it happen) - bad condition of plastic/plate in seat not pushing on seat switch reliably - bad connection of fuses or relays in holders. I've had to wire in replacement sockets for both. I think the ones in the engine bay are the ones in play here. We have been able to have the machine running with someone in the seat ready to operate and wiggle the fuses and relays to figure out which one. The seat belt light would come on. - bad wire somewhere - I really doubt the EIC or brake valve is the problem. For the 2 speed, bad switch in handle is most common. Have had a frayed/broken wire under the seat too. Good luck. [/QUOTE]
