Small Engines (Lawn Mowers, etc.): electrical problem, selinoid, soleniod

Question
I have a homelite-jacobson 12hp lawn tractor. The problem i am having is with the starter switch not being able to power up the starter. I can jump start the engine by the selinoid with key in on position. There is a safety switch with four wires going to it that is mounted under tractor.I have had no luck trying to find this part anywhere. The part number is JA-99156-0 for tractor model number UT33021.The switch has 3 prongs with one prong haveing two wires paired .Is there a way to fuse or bypass this switch to allow the tractor to start with key .Thanks . Ken  

Answer
 Hello Ken:

 The Easiest way Around your Problem is to Install a Push Button for the Starter. Bring a Lead from the Hot When Turned On Post on the Ignition Switch to One side of the Button. The Other Side of the Button is Wired to the Small Lead on the Soleniod. I have Tried to Junper that Switch before and had No Luck. Hope this Helps.

 Good Luck

 Respectfully
