Ahhhh people with time on their hands.
You know in life there are certain sights , sounds and smells that allways stay with you.
The indicator in petrol that gives it colour and smell.
The odorant in towngas, gives it smell.
Transmission fluid colour and smell
And now today after cleaning out my Vacpump, flushing, re-oiling, the smell of that oil comes rushing back.
I managed to get it everywhere, washing does not get rid of the smell, OMG I'd forgotten how much I hate it.
Any way by 8pm I had the 90 evaced -30" of mercury, gauges look good, tomorrow we will see.

Vettech:

Well evacuated the system to -30" mercury, held vac over nite.
Wacked in 1/2 a can of gas.
System started running, cool vent air, but was cycling very quickly, so put in more gas, system then shut down.
Switch off, look for cause, no power to comp clutch.
With engine on, A/C on, hot wired it, clutch & cycling switch & hi press switch all OK.
But no 12volts coming from the A/C Clutch Relay, in fact I cant even find the relay ????
So! Currently I have two (2) issues. (For now!).
1. System short cycling, could be low gas, but since it is sucking down into neg values, it's most likely a blockage, Orific tube 1st suspect.
2. No Power, need to find the relay and fix this first.
To fix, clean, replace the orific tube requires opening the system, loss of gas, re-vac the system etc etc....
DOES ANY ONE KNOW WHERE A/C RELAY IS .?
