My 312-A does not have power to starter

[lastoja 43]

I have replaced switch and solenoid to starter no power to starter. Power to 15 amp fuse but no power to 5 amp fuse can some help on what the problem may be.

What year is your 312, check out the manual section and it should list an electrical diagram for your tractor.

Two tractor model numbers for 1986 - 21-12KE01 and 21-12KE02. These use a K301 engine with battery ignition.

 

One model number for 1987 - 21-12KE03. This one uses a M12 engine with magneto ignition and has a low oil switch in the starter circuit.

This 1987 8-Speed wiring should be the same except the clutch neutral switch will be the hydro transmission neutral switch

 

The two years use different ignition switches so make sure you have the correct one. You do not want to release the magic smoke. The 1987 low oil switch has special instructions for removing the switch without damaging it.

 

The 15 amp fuse powers the ignition switch.

From the ignition switch already fused by the 15 amp fuse the 5 amp fuse powers the gauges and idiot lights.

You may have the wrong ignition switch.
