Title: Identification of plug & socket
Post by: Tick Tock on 27 July 2022, 17:58:36
Hi Guys, Just crawling around underneath the Omega doing a few pre-MOT test checks and came across this broken wire. Repairing and soldering / sleeving shouldn't be a problem, but it would be nice to know what it's for. Near side, bottom of engine near sump flange 2.5 V6 manual. Cheers.

That plugs into the white socket at about 8 o'clock in the photo.

I unplugged it from the white socket to repair the wire - I suspect it may have something to do with the air-con, but that's not worked for many a year and is always set on ECO.

It's now repaired and doesn't make any difference from before. Maybe it took a fuse out when chaffing against the chassis?

It's the A/C compressor clutch connector. When energized an electro magnet near the front of the compressor 'clunks' and locks the compressor drive to the spinney pully that runs off the 'fan' belt. The gubbins in the compressor then start compressing the gas in the A/C system. You can tell if the compressor is engaged because there is triangular shaped assembly on the front of the compressor. If it's stationary with the engine running, then the compressor isn't engaged. If it's spinning, then it is.

However, if there is no gas, or too much gas in the system, then the electronic thought police grass that up to the electrickery, and the compressor is clutch is not powered. There are also fuses and relays which if faulty will stop the compressor clutch engaging.

More likely to have leaked all the refrigerant out. But yes, fundamentally that's why it didn't work

Replies much appreciated thanks. With the air-con not having worked for many years, I'm guessing there's little or no refrigerant left in the system anyway.

It may have been a futile attempt to repair the broken wire under the circumstances, but it would have annoyed me with it just dangling there anyway.  :(

Part of the MOT test is 'no damaged or dangerous wiring"  ;)
so it was worth resolving  :y

Hardly dangerous.
