Hi Kenneth, my name is Jason.

Disconnect the yellow wire from the CDI box. Does the temp light stay on or does it turn off?

Customer: replied 3 months ago.
Disconnected yellow wire at CDI that goes to oil pressure switch. Lights still on. Disconnect and yellow wire at indicator lights, and the lights were still on also.

Is your CDI box labeled as far as the wire colors go?

Customer: replied 3 months ago.
No labels just color. I can pretty much tell you what each color goes to. I've been staring at wiring diagrams for over a week.
Expert:  Jason replied 3 months ago.
You should have 2 red wires on the CDI, and 2 yellow wires. Do you have a red and yellow that are right next to eachother? I'm attaching a picture, see attachment.
