good morning to all-- i have a model 310-8 kohler engine- all of a sudden i keep blowing the 5 amp fuse when i turn the key switch to the on position- ? i just cannot pin down the cause- should this fuse be energized in only the on position i would think it would only be when you turn the key to the start position- i am thinking i may need a starting switch/ any suggestions thank- you !!

Sounds more like a 'dead short"--can you trace that wire? Do you have the diagram for that tractor? That can be had from TORO website..

Also--can't be much draw--with only a 5amp. fuse..

Yepper--you could install a new switch, but , basically--that's just throwing parts at something that might not be....

I would want to knmow what is going on, first..

Let me interject another idea--as this happened to my Scott's mower.
Little mites , or some insect--got down in the key hole, and made a nest (twice)--I cleaned it out best I could with an ice pick--then compressed air, then gave it a shot of CRC electronic cleaner---now I stick a little wedgie in the key hole when done mowing....

Stuff never ends...

check to make sure the bare parts of the switches spade wire terminals under the switch are not touching each other, they can get bent when installing a new switch too, they bend easily... is the battery holding charge?

What is the long model number of your tractor? Some of the wiring diagrams Toro has posted are not correct for the 310-8. The engine spec number would help.

In the instructon booklet that came with my WH 211, it has a schematic for the 310 which shows a 5 amp fuse in the hourmeter/voltmeter circuit and a 15 amp in the solenoid/start circuit. Not 310-8 specifically.
The 5 amp would blow if the hourmeter or voltmeter is defective. Attaches to a pink wire. It's energized in the 'run' position, only.
The 15 amp would blow if the solenoid/starting circuit is defective. Attaches to a red wire.
Headlights are AC, off the engine with no fuse, right?
UNLESS, as Garry says, published 310 schematics sometimes aren't correct.
