<VV> A/C Adventures Continue... still

[Lon Anderson]

No Bill, I'm not essentially saying the same thing... The compressor will not run if the ground from the mercury switch is off. If the compressor isn't running, it cannot suck the refridgerant from the can. 

That is different from what Timothy was saying.  He stated: " The reason the manual says to 
remove a reverse lite assembly and then lower the deck lid is so all the cooling 
air is forced to go thru the condensor instead of bypassing it. This is so the 
high pressure side does not build too much pressure which can damage the 
compressor, cause (weak) components/hoses to explode, as well as put too much of 
a load on the compressor. "

He doesn't mention the ground switch needs to be on in order for it to run, and the only way it is on is if the lid is closed.
Of course, I'm referring to a stock '66 or '67 A/C system. If it has been added on from something else, or the wiring has been compromised, the compressor may NOT shut off when the lid is raised. 

So, say if someone is wanting to add refridgerant to a 66 Corvair on a 35°F day and think they can do it because the air is cold enough to let it run while the lid is open, it won't work. The compressor isn't grounded.
The 66 & 67 are the only ones with the mercury switch... (for those who didn't know).
Later,
Lonzo

Yes, and the Reason for the mercury switch is to ensure air flow through the 
condenser, so you are essentially saying the same thing as Timothy.

not run the compressor without the lid being closed... due to said mercury 
switch referenced in earlier post.
