Tecumseh switch

I am working on a Tecumseh HM100 on a generator for a friend that the mice got into and ate the wiring to on/off switch. I have replaced the wiring but don't know the sequence for the three terminals on the back of the switch. Also, this engine does not have electric start at present although the block has holes to mount the starter. Is it just a matter of buying a flywheel with ring gear and a starter to make this work?  Thanks for your help.

    Is the switch on the generator? That would require a schematic for the unit.

    Roy:  No the switch is only from the engine. One terminal is hot from the mag, one goes to ground and the third goes to low oil switch.

    Turn the switcch on and check for continuity between the terminals. There should be none between two of them and continuity between one of them and the third. These two will be ground and the low oil switch. Now check between the other terminal with the switch off, it should now give a reading to the ground terminal. I have never seen an HM100 with a low oil shutdown.

    Roy:  The engine is on a 6250 watt Generac generator so it may explain the use of the low oil switch.  I will follow your continuity instructions to check switch out.  Thanks.
