LS J2023H Ignition Switch Problem

[texascedar]

I shut down the tractor this morning and went inside for breakfast. When I came out to start it there was not dash lights nor would the engine turn over. I removed the panel to which the switch is mounted to access the fuses. The fused ok. While the panel off and switch still connected I turned on the key and the dash lights came on as did the starter engage. Great, back to work.

Worked two hours when engine started losing rpms, then it would regain rpms. This happened three times in about 10 minutes before it finally died at which point there was no dash lights and the starter would not engage.

I removed the panel again, this time disconnecting the switch. The disconnected plugs at the switch tested 12.94 volts indicating to me a good battery and a bad ignition switch.

If the main 40amp fuse were blown would the battery test 12.94 v at the switch?

Is there something I may be over looking?

Are safety kill switches wired thru the dash and ignition or just ignition? I am thinking sinct the dash is dead there is no need to check kill switches.

Thanks

Last night I sprayed the switch with WD40 to sit over night. This morning I reconnected it. When I turned the switch on the instrument panel lit up but nothing from starter like dead. Within seconds of turning the switch on the instrument panef faded away like dead.

Any help? Thanks

I own a J2023H tractor and yesterday I was trying to go forward / reverse and I heard a "click" and the engine shut down. Same happened when I tried to engage PTO. No issues on raising loader or rear attachment. Anyone know how to fix it or better yet where can i get a service manual or electrical diagram?? help pls

By your description, it isn't sensing your butt on the seat. So maybe a seat switch or wire in that circuit would be a good guess.

I don't know your tractor - I've got a Kubota. If all safeties are not satisfied the dash appears to light normally, the starter simply will not engage until safeties are happy. Check your manual or check another model of the same tractor when safeties are not satisfied to see how it reacts. From my limited experience I don't think you have a problem with your safeties, you may have a switch problem. I'd just hate to suggest you replace the switch only to learn that wasn't it. Dig deeper into it.
