can not locate ac freon leak.

[chris989]

It has dye and i can not see any traces, The compressor is a new real sanden 4711 sd7

my gauges are Yellow jacket analog,

I have had a charge of 100 psi for 4 hours now and still dead on 100,

shop has AC and temperature is a steady 72. I ordered a new condenser and evap core but hate to go through the work to not have it solve the problem..

it has all new Galaxy hose (usa) and fittings,

My gauge is hooked to the filter.dryer,,, I can only think that when i remove it the schrader valve is leaking and with the gauge it is captured,,, I have soaped it with no bubbles.. I might hook a hose to the shrader and put the other end in a cup of soapy water??
