Solonoid

[Irv 115]

Anyone know how specific solonoids are to certain model tractors. I need one for a 416-8 (kohler) and elec. drawing calls for #110979. thanks

Can you post a picture of the one you are looking to replace?

Go to any auto parts store and get a three post solenoid. The two end post are the battery and starter and the center post is for the actuator wire.

Or the 4 post. Just don't use the 'I' terminal.

Do NOT ground the "I" terminal. This terminal connects directly to the battery when the trigger terminal is activated.

The 'I' terminal on a 4 post (typical of a Ford solenoid) sends momentary full power to the coil on vehicles that use a resistor in the primary power to the coil. The 'S' terminal energizes the solenoid from the ignition switch. Don't confuse the 'I' terminal as being from the ignition switch. It won't energize the solenoid.

Great diagrams SOI.

Save Old Iron, you are a wizard at this. There should be a place to permanently store these for future  use and direction. You always come with exactly what is needed to describe a particular electrical problem.

Thanks for your input guys. Tested the solonoid (jumped the trigger from the battery) and it worked so it's probably a safety switch or ignition switch.
