Hi Need_another_tractor, welcome to the forum!

I believe you have a pressure switch just before the gauge?
It should look something like this:

Auto part Engineering Composite material Metal Titanium


The switch is needed because it cuts out the electrical charging when the engine is off, and during cranking/starting the engine. When the oil pressure is up, the switch closes and the alternator starts charging.

If you want to block the oil pressure line, you have to do that after the switch, otherwise you will not get the battery charged.

Thanks!! I will just replace everything. I just wanted to make sure I could run it a little, just enough to get it back down the road. Probably looking at a 30 minute drive. Not fun taking it apart not near my shop.

Thanks for the help!
I see, a short drive without charging would not do any harm. If you want charging, you can connect together the two wires at the switch. Just remember to disconnect them when the engine is turned off, otherwise the battery will slowly be drained through the regulator. That is why there is a switch.

Happy wrenching!
