John Deere 110 loader backhoe, no power to fuel shutoff solenoid

fishinfool · May 2, 2020

Trying to troubleshoot no start issue on JD 110.
Fuel shutoff solenoid is not clicking "on" when key is turned to "on" position.
Replaced Fuel module at fuse panel, still not getting power at plug going to fuel shutoff solenoid.
Tested solenoid, it works.
Hotwired the solenoid in place, it clicks, tractor fires right up.

One theory at this point: PTO circuit may be engaged (in spite of PTO switch off) telling solenoid not to open.
How to check? PTO shaft lurches a bit when cranking engine over, is this normal when PTO not engaged?
Any other safety, fuel shutoff override switches i should be aware of.

Open to any other suggestions, tractor is on a remote, fly in only ranch, id like to be more prepared on next trip to troubleshoot/fix

Thanks

Doug

I'd suggest getting the service tech manual for the 110 TLB

Thanks been,
I致e never worked on one of these tractors, doubt I値l ever see the opportunity to work on another.
Investing in a service manual may be the smartest approach - and leave it with the machine for the next guy.
Would have also given me reason not to post my question on this site which has proven to be a wonderful source of knowledge and learning.
In short, if you have nothing helpful to contribute, please don稚 bother to reply.
Thanks,

I can send you a .pdf manual if it helps.

It may be a small link ( can’t remember what it’s called) that controls the amperage to the solenoid. High amp to pull in and lower amps to maintain the open position. A ten dollar part. If full amperage is constantly applied to the solenoid it may burn out.

For interest the solenoid may activate the injection pump but does not shut off the fuel. Don’t know if this applies to your loader.

On my 4200 JD heating and tapping on the solenoid while working the priming pump usually works when there is no click.
