John Deere 300b industrial tractor

[Boobakar]

Does anybody have a pic wiring diagram for 300b 1978(?) for ignition switch? Also, isn’t it just:

Wire to battery : from starter though
Wire to distributor
Wire to starter solenoid on starter

Am I missing something? Thanks for any help::

No schematic here, but don’t forget the neutral start switch.

Hey. Thanks for the help! Where is the starter switch (#4 on schematic) on the tractor? Is it under the shift levers right in front of seat? I have had tractor for ten years and never knew it had a switch??? Thanks!

My memory fails me. I think it is under the cover that is over the shifters. I think it will be behind left side shifter, on top, just behind the joint that separates the reverser housing from the transmission/differential housing. If it is in fact defective, there is an adjustment procedure (shims) for that switch.
