Thank you so much for the excellent video. Very helpful. I was trying to troubleshoot why my Deere 1445 Front deck tractor would not start, I've been tracing down the fuel system, and came across your video. Sure enough I had one side of the coil / solenoid failed. I followed your Ohm test procedure. I recently ordered new solenoid from Deere dealer, installed, and my machine now runs great. Thank you.

Thanks George: This helped me tremendously with my x758 with starting issues. Your diagnostics solved my sporadic starting problem. I replaced my solenoid and now it's working all the time. Udaman!

Thank you, i blew up one fuel solenoid and did not know why ,, i thought you have pos (white) and neg ( black) red wire did not do anything (i thought) Then it sucked in all good but after 30 seconds boom , i did not know where the red wire went , now i know white is only positive momentary then red stays positive to keep solenoid engaged , so helpfull thanks again

I don't have a John Deere, but a Mustang 2040 skidsteer with the Yanmar 4TNE84 engine. It started to cut out on me and then stopped all together after a minute or so. I tested the wires going it to the Solenoid with a 12 volt light tester. As you explained, the light came on with the white wire for about 2 seconds then went out. The Red also came on but the light went out when the white one did. So, the I bypassed the seat switch as it was the easiest to get to, then the engine ran fine! Thank you for saving a bunch of time & hassle to find the problem.

Thank you so much, helped allot! Especially that you explained differences between holding and pulling cords.

Great video! Thank you.

Thank you so much, this helped me with Kobelco SK50 starting problem. Engine Yanmar 4TV88.

Thank you

Thaks for video .greentigs

Thanks I’m going threw a voltage problem with the white wire the red I’m getting 12v but only 3 on the white not kicking it in

Hi George, I am testing all safety switches so I started by bypassing all the safety switches by hotwiring from ignition to solenoid. Runs fine, but I pulled the solenoid, tested and replaced it. Now, I turn the key and the plunger retracts for a couple seconds. So, while hot-wired I cannot reinstall the new solenoid because when it reextends, it will kill engine. But why, if the seat switch is bypassed?

I have a 4105, I started it up and smelled something electrical burning followed by some black smoke. Shut it off and now it won’t start.

I had this fuel shut off problem - took quite a bit of head scratching... turned out my knee had hit the emergency cut off... so obvious after the fact!

It's not clear to me which mechanism is the solenoid valve in this video.

I'm not believing the seat interconnect with the solenoid starting function because I can start the tractor without sitting in the seat. The seat safety switch only matters if the PTO is also engaged.
