3720 John Deere
My tractor died today just like the battery disconnected. I have power to the lights and to the starter terminal from the battery. No connection to the ignition switch. Does anyone know if there is a fuse or fusible link that could have blown and where it would be located. Any help would be appreciated.

F1 (D) is a 30 amp fuse for the Key switch. There is also a relay you might check K2 (B) Start relay.

Thanks guys!! It was the fuse you mentioned Dirt. Dealer had me tracing fusible link wire first in their diagnosos sequence. Been a busy snow winter here with over 60" since mid November so the old girl has to run on command. Over 1200 hours on the '06. First electrical issue I've had other than fuel sender. Once again thanks as this is a daily stop on the net to visit this forum for info.
