john deere 3040

Howdy, Got an old JD3040 and I have alternator problems. The alternator has 2 leads: a thick red one -I bet this is alternator output and a more narrow gauge wire leading in to the cables entering the cabin. I bet this is the field voltage. This terminal reads zero volts when tractor is...

Hi I would need a wiring diagram for a 3040 John Deere tractor . I'm having problems with it the ignition light glows dimly when the tractor is switched off and runs the batteries flat as well

i just bought a 3040 and have problems starting it in cold weather. is there a heater plug in it? i had an old one and you just turned the key a bit and it heated it but this will not work on this tractor! please help?! Thanks:confused:
