Yet another Air Con Thread....

[akkakkman]

Hi Lads, read through a few of the aircon threads on here and almost found what I wanted to know
The magnetic pulley is not engaging when the aircon is switched on, I don't know what way the gas is (full / empty)

So there are two wires going to the compressor. Multimeter on the one with the smaller connector (pink/blue wire) gives me 12v other one with the larger connector (yellow wire) gives me nothing and doesn't look like it is a ground wire either.

There is a reply from steelroe in this thread:

And Kace and CJ in this thread:
http://www.fto-ireland.com/forum/phpBB2/viewtopic.php?f=2&t=3649&p=23620&hilit=air+con#p23620

That talk about a test to check if the compressor is working, but don't give full details of this test.
So there's two things to check;
1. The connectors are supplying correct signals (but what are they !)
2. Override and provide my own signals (again what should they be, there are 2 wires !)

Don't want to blow anything but I'm guessing supply 12v to both wires...in the hope that the second isn't a feedback wire of some kind

Any help greatly appreciated. Its getting hot out there

I've no gas in mine at all, when changing the matrix NOTHING came out

Fair play for having a search around first with so few posts, and welcome!

Reckon the magnetic clutch signal to engage is the red/blue wire based on a schematic for a completely different mitsubishi here..

Probably the magnetic clutch thingy so, and at £240 from Camskill it can stay broken...

Welcome to the site. Have a good look over the FTO electrical wiring manual @ http://www.fto-ireland.com/downloads.html , theres bound to be a detailed diagram in there for the a/c system.
