A/C Pop DeLo A/C Anomalies

["content22207" <brobertson@xxxx>]

Remember reading old posts Re: high pressure A/C switch inside
DRIVER'S wheel well. My compressor output line is defenitely
uninterrupted there...

Stuck head inside passenger wheel well on way to work. Never really
worried about anything in there other than heater core because my R134
conversion went smoothly (unlike Dave Swingle, I jump compressor
inside engine compartment)...

Despite wiring diagram, are two indeed two electrical connections, and
what appears to be a pop off valve. What has me confused is
accumulator is in low pressure return line (what does it accumulate?
Gas? Old Lincoln accumulators are at bottom of condensor and store
liquid freon) and switch in it is 3 conductor. Wiring diagram clearly
shows 2 conductor low pressure switch. If 3 conductor switch is low
pressure, indeed opens at 25+ PSI, but what is third electrical line
for? If 2 conductor switch is low pressure (correct me if I'm wrong
Louie G, but didn't we force your compressor on there in SC), is on
high side as I originally claimed, but what in the world is that
switch in accumulator?

Will fire up DeLo at lunch and experiment with switches...
