Vintage Air Compressor Cycles On And Off

The air pressure cycles a clutch mechanism.

Vintage air compressor cycles on and off. I think the motor is going out (stink of ozone bad when it runs). Say your car takes 1.75 lbs. As this switch continuously cycles on and off, the ac system operates its electrical contacts which subjects the switch to a high amount of wear.

I would welcome any ideas and suggestions. This can be measured by multiplying (height x width x thickness). I pieced together an ac system, nothing on it is factory, i wired it with a relay, a gm style cycle switch mounted on the drier and a vintage air binary switch on the high side.

The a/c never gets cold, so meti s even blow hot,and mpressor clutch infrequently cycles off. Its fairly quick and sporadic. Vintage air gen iv, sanden compressor, binary switch.

It could also be caused by the compressor shutting off and trying to come back on too soon afterward. As long as it isn't rapidly cycling on and of it is working properly, however if it is rapidly. Over time, the contacts wear out and the switch must be replaced for the ac to function.

I still need to run it more to make certain but so far, so good. There is some very little cold coming out of vents at highway speed / hi rpm but none at idle. The compressor clutch kicks on and off randomly during the driving.

The system works great im getting 50 degree air and the evap box isn't sealed yet, trouble is the compressor never. Compressor strongly cycles on and off and pressure fluctuates between 20 and 45, low side port tube is frosty but no freon will flow into system. Typically this means that you are low on freon.
