Tried to start the machine but it's completely dead. I've checked all the connections, batteries, starter and grounds—batteries are fully charged. The start fuse has no power going to it. I jumped the big solenoid from the big terminal to the small one and got the dash lights and a beep, so that works. I pulled the key switch and there's no power at the terminal marked Bat. Not sure where to go from here without an electrical diagram. Machine ser.# 6CR002231.
