TC35D Hydro Hi/Lo shift problem

I know the OP's issue has been resolved.

But, your post highlights what is often best checked before anything else. In automotive type wiring, and especially for trailer lights, checking grounds is a really good place to start debug.

I like to have a test light and a multi-meter handy. And supplies to clean dirty connections.

In some cases, when there is a malfunction of more then one electrically controlled issue on a machine, it may lead to the earthing connection failure, which might be common to those issues. If You have a multimeter, check resistance and circuit continuity of the earth wire concerned. You said You touched the hot wire? The wire heat comes on because of increased resistance in a circuit. The resistance increase could be caused by bad earthing.
Find earth connection location if You have wiring diagram. It could be loosen or rusted.

Not sure if it could help

Thank You, Robert. Yes, my experience comes more from automotive engineering, than from tractor. But there's not a lot of difference. Except we have rust, oxidation on the vehicles and ... rat nests in tractors
Oh, I need to check a subject of rats under my tractor's dashboard :laughing::laughing:
