Hello;

I have a 24221125 Neutral switch, I'm trying to figure out if the switch is working specifically the Transmission Range Switch (B,A,C,P) wires:

Can anyone help me with a troubleshooting sheet for this?
The switch is on a 4L65E M32 Tranny.

I know there is suppose to be some logic for each shift position trying to figure out the logic and what voltage I should be reading when they are High or Low.

I think I might have a faulty switch but not sure.

Thanks!
