Thanks bastereo
Am half hoping it has leaky seals or something and compressor is ok. Pressure test will tell. Will have to wait a few weeks til I get back from Thailand!
Does anyone know what the voltage to the compressor should be? Mine measures a steady 4.8V with or without the AC selected.
Also found the aux fan runs when the ac inline low pressure switch (?) is disconnected, compressor however does not kick in - maybe favours lack of refrigerant also.
