Suspension, Brakes and Tires Discussion, New ELC compressor not working? in Item Specific Cadillac Discussion; I just received a new compressor, from Arnott. Their web page said
These are new genuine O.E. air compressors with ...
They look very nice, and appear to be just what they are advertised as. So I put the new one on the work bench, put a balloon over the output nipple, and ran the motor with a car battery. The balloon did NOT inflate, just sorta expanded to its un-inflated round shape. When I removed the battery power, the balloon instantly deflated. And yes, the balloon was tightly rubber-banded around the nipple.
This doesn't sound right to me, but I need some experienced confirmation, before cut'in loose on Arnott. If it will not inflate a balloon, how could it do anything for the shocks, supporting the weight of the rear end?
