Replaced the 20amp fuse and it started right up. next day, ran for a while, turned it off, and it would not turnover. fuse is good. lights and service meter come on when key is turned. manual PTO clutch is disengaged and emergency brake is on. Hear a faint click when key is turned on and then off, but other than that, there is no sound. Could it be the solenoid? Any ideas ?
