Thread: voltage at Compressor clutch

Hi Ron that YSB106340 cable simply replaces the cable from the Alternator to the battery, is that correct ?

I found my problem with low voltage is a low price meter.

I used my Fluke meter and got about 11.6 volts, so the voltage is OK.

I did find the compressor clutch problem was caused by a bad Expansion Valve. I replaced it yesterday and all is well now.

I now have Ice cold A/C blowing just in time for winter to set in.

If I recall correctly, there was a TSB for the expansion valve.

My aircon is behaving weirdly, a lot of the time it is not cold but then it will decide to get a bit cold.

Also the fans seem to run a lot harder than my old beast, but that may just be a side effect of it not being cold.

It has had the mod done so I am looking for the cause of this now

Rave also only lists three options for the system not getting cold, expansion valve, low coolant or stuffed pump

It seems it may be worth me looking at the expansion valve

Steve. Have you carried out the temp differential test before and after the drier? Seem to recall RAVE referring to it.

Thanks mate I will go through those over the next few days

As Ron b has mentioned, there are a few mods.
I have personally done the air gap by removing the shim, it worked fine after. I have also added a wire between the alternator and battery, I didn't know about the mod, but the power difference was over 1 volt, so I put a heavy cable in, and been working well.
You could fit a direct feed via a relay to the compressor, having the existing power to activate the relay, I think this is fine, but read above about a resistor, so I would check before hand. There is also a pressure valve which may be at fault. Again, I would start with the easy stuff. I found my fault by holding a screw driver to the clutch, it was magnetic, but not engaging.
Good luck with it.
