There I was in a clearing at the cabin...cutting wind downed trees to logger length and grappling them into piles. Nice easy work for the tractor. Shut tractor off each time while chainsawing. Started right up until the last time when there was a click under the dash...then nothing. Checked wiring connectors to seat and range selector safety switches...everything appeared okay. Checked all the fuses visually and with meter...all okay. Battery voltage was a little low (tested at 12.3 volts)...so I jumped the battery ...still nothing. If the unit sat for a long while a turn of the key would give a single click from under the dash...and then nothing. In the 'off time', in the switch 'on' position, the dash lights were erratic...sometimes slow to come on one at a time and not very bright...other times bright as anything and immediate. Hazard lights and headlamps didn't work at all in the switch 'on' position. Don't know how to hot wire the starter and didn't want to possibly cause more damage so I jacked the loader and ballast box up and chained them to the ROPS. Then used my 4x4 Dodge Dakota to tow the the 4100 about a block and a half back to the shed to escape predicted storms. (Trust me, it was a PITA job that I hope not to do again. Can someone clue me in on how best to hot wire this unit?) Once in the garage I disconnected the battery, cleaned the posts and cables and jumped again with a fresh battery. Still nothing. There is no schematic or wiring diagram in the operators manual so I have no idea if there is a solenoid or relay under the dash. Any of you helpful folks have an idea what the problem is...and how to fix it? BTW this tractor is in the far north woods of Minnesota and the closest John Deere dealer...mostly lawn and garden but now some compact...is 35-40 miles away. I'd really like to avoid having to have it hauled to the dealer if possible.
