How to replace a 4 terminal solenoid

[@jdprice3043]

Thank you for your help

[@SG-ve9vm]

Thanks for the video. What might happen if you had reverse polarity on your solenoid, if your cable from the battery was on the wrong terminal. Thanks

[@oldschoolmechanic7771]

You are welcome. The starter will most likely spin backwards

[@reisehase6591]

Thank you for this video. Could you please tell me what the two small terminals are for and how they are connected?

[@oldschoolmechanic7771]

The two small terminals are for engaging the solenoid. One wire will carry power from the key switch to one of the terminals. It doesn’t matter which side it goes on. The other wire is a ground wire and serves as a safety switch and has to be grounded to make the switch work

[@kamren4703]

What size socket are the two bolts that hold it down to the mower? 12mm? Can’t get mine loose to remove the solenoid.

[@oldschoolmechanic7771]

Either going to be 3/8 or a 7/16. Occasionally you might see a 10 mm and sometimes they will have a nut on the underneath side

That's all fine and dandy which one of the post is ground if you're not rearing one of my posts says I and one says s... Does it matter or does it just activate the switch and it doesn't matter

[@oldschoolmechanic7771]

You can use either one of the small posts as ground on the solenoid as long as it is not on the same post as the power wire to engage the solenoid

Thanks for your video. What is the blue wire, and does it go to the ignition switch?

[@oldschoolmechanic7771]

Yes the blue wire is coming from the switch and it throws power when the key is turned to the start position. The other is a ground wire and is basically another safety. Thank you for watching

[@awesomecowboy]

@@oldschoolmechanic7771 thanks, so I'm guessing the blue wire would go to the "S" pole on the switch, meaning solenoid? I'm repairing a beautiful 1971 simplicity broadmoor 😄

[@oldschoolmechanic7771]

Yes it should be going to the S One of the old simplicity’s nice. Interesting how the old ones were made

[@kevinspahr6632]

Was there a cover that you had to take off to get to the solenoid? I'm having trouble finding mine on an Ariens Edge 52 zero turn.

[@oldschoolmechanic7771]

That solenoid was out in the open. Your edge solenoid should be on the back side of the battery between the motor and the battery Could be tucked back underneath a little bit. Locate the battery and solenoid should be close by

[@suzieq8379]

Mine is under my seat under the frame so hard to get to follow the red wire from battery

[@oldschoolmechanic7771]

Not sure why they do things like that. Guess they don’t want you to work on it

[@DanielJensen-lp1jp]

​@suzieq8379 mine too,all the safety switches been disconnected or bypassed.I The wiring is a mess. Need an easy access door in the back.

[@oldschoolmechanic7771]

@@DanielJensen-lp1jp uggh that is never a good thing. Trying to figure out what someone else has done sucks

[@Meech2x]

Thanks man

[@oldschoolmechanic7771]

You are welcome glad I could help

De donde viene el cable azul y de donde viene el verde?

[@oldschoolmechanic7771]

Sorry I don’t know the language

​@oldschoolmechanic7771 where do the blue wires come from?
Where do the green wires come from?
