Issue with Kohler Genset

[TomPurdum]

Good morning all. I am having some issues with my Kohler 8C generator. I replaced the control board and have a wire that doesn’t seem to have a home. I looked up the wire on the schematic and it appears to be from the oil pressure sender. I can’t for the life of me figure out where to hook it up. The unit will crank, catch and then run very poorly until I let go of the starter switch. I know this is likely from the safety relay because of the oil pressure sender. Can anyone help me figure out where the wire connects? Pretty please? It’s the loose wire in the photo, wire number 13. Tia.

Compare the board removed with the one installed, are they exactly the same?

Sadly it got tossed out. I thought I replaced wire for wire when I swapped boards.

I'm thinking the other board had another connection. Unable to say for sure, and I don't have a 8C manual

Where does the other end connect to?

I’ve tried tracing it, but it gets lost in the giant bundle of wires. It’s labeled “13” which translates to oil pressure sender in the manual. The old board only had the sockets for connecting, not spade connectors

Fuse maybe

Right next to the purple power wires there appreas to be a blue Female connector without a mate.

There is a wire there. It looks as if it’s a single connection, but it could be a double. I’ll investigate this weekend

Could be. I’ll look when I’m out next.
