Finding the right fuel solenoid

[Wirespider01]

Hi everyone.

i have a Cub Cadet 13WQ93AP009 LTX 1050. Its garage kept and has 200 hours. The engine is a Kohler KT735-3012 MTD.

I used it the other day and after about a hour it shut off. It was completely dead. I got it in the garage and found the main 20 A fuse was blown. Replaced it and it popped as soon as I turned the key 1 position. Guess that would be run. It has the reverse safety switch. I don't like it but I didn't engineer it. I just ride it.

I went through and eliminated all the safety switches first. still blew the fuse. now I had about 5 blown fuses. Anyhow, I unplugged the wire harness that feeds the ignition/charging components. the fuse didn't blow. So, I figured it was probably a shorted voltage regulator/Rectifier. Seemed like a appropriate part to start replacing. I also checked all the wires for shorts and noticed the red wire going to the fuel solenoid shut off. So I unplugged it from the solenoid, plugged the wire harness back in and it didn't blow. I wanted to be 100% and I plugged the red wire back into the solenoid while the harness was plugged in and the fuse didn't blow. The mower started up and ran perfect. So now I'm confused about what shorted. I would still like to change the rectifier that I already got in the mail today and the fuel solenoid. The solenoid is a being a issue though. All the parts diagrams online do not list a number for the solenoid. I checked Kohler and they didn't either. but at the bottom of the parts list they had a fuel solenoid rebuild kit. I searched the number and at some stores its over $100 and comes with what looks like the mounting gasket for the entire carb, the bowl gasket, the solenoid and the solenoid gasket. the ones I've changed just unscrew and you screw the new one in. I emailed Kohler and asked about it and its been since last week with no response. If I can just replace the solenoid I need a number. when I put the engine number and solenoid into google search a lot come up. My problem is I have no clue if the ones coming up will fit as I don't have a number. I'm hoping someone has worked on this motor before and can give me some advise.

Thanks for any help.

They went from a one wire solenoid to a two wire hence the kit. Part no. 32 757 01-S. $56.26 retail.

Sounds like wire on anti afterfire solenoid on carburetor is chaffed and shorting to ground and popping fuses. Purchase a new solenoid and replace, track down wire bad spot, or, bypass the solenoid and be done with issues forever. Your call.

The Kohler kit PN is 32 757 01-S.

But trying measuring it and see if it matches the following. If so then there is an aftermarket version under Briggs PN 694393. Now the Briggs OEM solenoid is just as high priced but on Amazon there is one for about $12


Also the Briggs one may look like this so when ordering order the aftermarket version that matches your current solenoid.


Just note Amazon is now requiring $35 minimum orders here for free shipping. May be only be $25 in your area just depends if they hit your area yet.

Mine already is a 2 wire plug. a black wire from the plug comes out and attaches to the engine. Checked continuity with meter and it's good. I also had checked the red wire for short to ground but found nothing. Is there anyway that the ground and hot can't short inside the solenoid?

I just did my Husky Zero turn solenoid at the beginning of summer. I just clipped the plunger off and ran it. It never backfired. I got the new solenoid from Briggs and put it on. It has backfired several times since installing the new one. When they work I don't mind them. Generally I've never been a big fan of them.

If they changed the design and added another wire where would it go? It is already grounded. Wouldn't you need a new harness or at least a new plug for the solenoid to accept a 3rd wire?

I put a pic of mine in here.

Thanks

The solenoid will have approx 25 ohms across the two terminals and infinitely from either one to the case.

Thank you I'll check when I get home.

Thanks,

I checked that kit. I'm confused as it doesn't show another wire for the solenoid. It has carb mounting gaskets, what looks like a bowl gasket, new solenoid and a new solenoid washer. It shows that the new solenoid screws into the bottom of the bowl. I'll post a pic. Oh and a zip tie is included.

I removed mine. it just unscrewed from the bottom of the bowl with a 1/2 thin spanner wrench like others I've changed. No need to take carb off. The PN you gave me was off a few mm off each measurement. I put in goggle search my engine model + fuel solenoid and I stumbled upon one with the right plunger tip and the same dimensions and I bought it. Won't be here till next week. Not sure if I'm going down the right path since it did have 34 ohms and didn't drop to 0 like it would've if it had a short. Unless something shorts when energized. Maybe it just has to be ran for a while before the ohms drop ri 0 and shorts out? I checked the red wire. Still haven't found any rub marks. I put a pic of my solenoid and the one I ordered.
