Problem isn't compressor -- takes extremely little electricity to engage clutch. Problem is cooling fans and hot freon in condensor. Even then problem isn't electrical (any more than endemic DeLo fan current draw), is reduced engine cooling capacity. On way home from Fall Foliage ran my A/C in I-95 traffic jam for several hours no problem. Temp would flirt with 220, but that's still within tolerances. Idle at that time (manually set) was 1,000 RPM, since backed off to 900 (spec for my particular PRV). Used "normal" A/C mode which allowed cooling fans to cycle with compressor.
