MF Electrical Problems

I"m looking for a wiring diagram for my MF 35,
3 cylinder diesel please. Have searched the site but am unable to find one. My neutral safety switch went and I have bypassed it but the starter barely turned. Now I"m not sure if I need to replace the control box or not.
Any help with this would be appreciated.
Thanks
Jody
 
A deisel will start and run without the charging system working at all in fact the only reason you need the alternator or generator other than to charge the battery is to keep the fanbelt tight.
If you have a hot battery you can jump the main cable terminal on the starter solenoid to the little start terminal and if the starter is any good it should spin the engine if nothing else is wrong. Make sure your fuel shut off widget at the injector pump is in the run position and all the air is bled out of the pump.
 
Thanks for the clarification.
Tractor was working great all day. Shut it off and would not turn over, click nothing. Bypassed the safety switch and had a little life but not enough to provide 1 revolution to the engine. Battery is new and seems good, starter is brand new (3 months and $800.00). Just wnated to make sure I wasn't overlooking anything before I went further into this.
Thanks

Hi, check also the battery connections. Is there any sign of diesel or oil leaking from the lift pump onto the starter? As 'Oldhousehugger' has suggested, try bridging a wire between the live battery cable and small terminal on the solenoid. This will show that the battery and starter are OK or not.
