PT422 electrical diagram

[Marks481]

Anybody have an electrical diagram for the PT422? I checked the manual, and I have nothing.

In the right side of the engine compartment I have two connectors which are unplugged. A female bayonent connector on a white wite which has 12V when the ignition switch is on, and a male bayonent connector on a gray wire. Anybody know what these do? The tractor runs fine without plugging them into each other.

Get an engine manual for your engine and it should show you what those are for.

I had some spare wires hanging off of my Kohler, and the Kohler manual had them identified.

Good call. The Robin America site had all the manuals online, and the engine manual had the diagram. The gray wire is the oil low pressure alarm. Sure enough, the oil pressure sensor wire is gray. I am thinking that I will hook it up.

I hooked up the oil pressure switch to a light that I added on the console. I think it is a really good idea. The light sometimes flickers at low idle and I know to up the idle speed a little.

Great!
