My exc took a crap on me. It started with the throttle not working so I bypassed the electric throttle to finish a job. Got it home and finally decided to work on it. Started it and messed with the control buttons changing the digging setting. Throttle worked somewhat but switching to manual throttle didn't work. Then it got to where it wouldn't shut off for a few minutes and in the end I have no response from the key to do anything. When it wouldn't turn off I tapped on the disconnect by the batteries and it would kill it. Now I don't hear any click from that and nothing. I did take jumpers and bypass it to no avail. Does this do more than disconnect the battery from the machine? Either it or the pcu has taken a dump I'm guessing. Been a bad month for me, this is the fourth machine to go down.
