: Good News and Bad News, I just bought the cutest John Deere 40S and after rebuilding the carb it runs great but..... Last night it quit and when you switch the lights on, the tractor quits. The battery was in with negative to ground so I am checking the voltage regulator and key/light switch. What I need is where the wires to the voltage regulator go. They are marked Bat, F and it looks like a L. There is also a wire to the back of the regulator. I will get the IT manual as soon as I can but would like to get this machine back together before that. Thanks guys . Dan

Hello Dan; on the regulator there should be three terminals, one marked F, this goes to F on the generator(thats field) second one is G or on some marked as A, this goes to A on the generator, third one marked with B, this is the battery power and goes to yer ammeter! Any problems just e-mail me and we'll try and get ya WIRED! Randy Swain
