I purchased the GX CS4 and durning the initial start up test while checking head pressure the 12 V converter shuts off and trips breaker around 200 bar. After unplugging it and letting it cool off and releasing the pressure on the line, it will start back up but trips again around 200 bar. The air compressor works perfectly when run off of a 12 V battery I have emailed GX several times with no response. Has anybody else had this issue?
