802 oil pressure switch. This is a Gov auction set

[PoP PoP]

Wires were cut off the oil pressure switch MT 7 and twisted together. I can understand someone doing this if the switch is bad. Not checked it yet. Assume they were twisted together to complete the fail/ open (I think) circuit. My problem yet again is which wire connects to which post. My thoughts are is that it does not mater. Here is the picture. From other photos on the internet, they appear to connect to the top and bottom post.

Here is how my 802A switch is wired.

There should be printed on the switch, C, NC and NO. Wire #115J is hooked to C. Wire #141A is hooked to NO.

Guy, I think you were looking at the HT switch and not the OP switch.

Here is what the TM has for OP switch connections.
143C to C
126A to NC

That's how my 802 is wired.

Your right! I was holding a page from the schematic over my head while laying on the couch. Had my foot up and the tablet in the other hand. Getting old.

I had not seen that. Missed it somehow.

Thise connections tend to vibrate off if they dont have enough slack.

If there even close to being to short i would extend the wires so you can zip tie the wireing to the sensor and not rely on the connections holding the wire.
