I can throw a shot of bang gas into the A/C if you feel like a drive to Ballarat at some point. I can even pressure/leak test with nitrogen now ( Total Tools have rent free bottles finally).

With regards to testing the electrical side. Just short the swithc on the receiver drier. What it does is cut the compressor out if there is to little or to much pressure in the A/C system (so shuts it down to protect itself). Don't run the system with the switch shorted. If the clutch thumps in on the compressor, that is all you need to know.Quote:

The RAVE manual on hand didn't show any details of the AC system, so I stopped when I got this far. Everything else checked out ok.
Bypassed this to run the compressor - no banging, it spins fine, but nothing gets cold, I'm guessing whatever was in there has leaked out but from where who knows.
The rest of the system and wiring all seem fine - the condenser fans come on when the AC is switched on and the idle up on the engine works too, it's just the compressor clutch not coming in as it should - not sure what drives the negative side of the coil. I can make it work no dramas, but rather than bypassing things to do this I'd prefer to find out where this comes from and fix it properly.
If anyone has a wiring diagram of the AC system for one of these I'd love to see it.
Cheers.
Re the tacho, yes - the W terminal is wired in and working, and is up at the instrument cluster, but the tacho itself seems stuffed. I pulled the cluster out as the tacho was sitting on 6,000RPM - so at full deflection with no power applied. Needle was stuck there. I moved it with my finger and if you move it to 3000 (12 o'clock) it falls to zero, but anything past that and it will fall to full deflection at 6000. No movement of all of any kind - guessing the unit itself has gone to god.Quote:

Hi Shane,
I'll have a look tonight to see what compressor it is... I might take you up on the offer - my plan is to get a RWC first, and then I might come for a drive up to Ballarat!

No worries, if you do "open" the A/C up. Buy a bunch of 'O'rings and check every connection you can find (and replace the Orings). I found 1/2dozen munched Orings and a couple completely missing in the Rangie here :oQuote:

Hi Shane,
I had a look at the compressor last night - it has "A" and "B" stamped on the top of it:

And "709" stamped on the side:

Is that a Sanden SD7 that you mention? (I couldn't find any other identifying marks)
Here is a picture of the alternator - cleaned up and wired up:

Here are the broken seat belt buckles:

And the replacements in:

The front end back together and looking schmick.. (Apart from the dodgy drivers side head light):

Stripped off all of these parts - while homestar was checking wiring - so gave them a good clean:

Removed this from behind the dash - a rats (or mouse) nest... Lot's of rat crap, and the smell was rather... Unpleasant:

Last night I was working on another project, so didn't get much done (apart from the rear seat belts)..
Cheers,
GG.
Yes that looks like a sanden SD series compressor to me ( have a look on ebay for sanden sd, they should look the same ).
I did that to one of my seats belts a couple of weeks ago. It happens when you try to fold the seats back down with the seat belts in the way. The seatbelt does still work, but it doesn't look pretty!
