the call would be great but I have a client coming in shortly
the engine also does not idle down after warmup
Mechanic: Dan, Technician replied 3 years ago

COMPRESSOR WILL NOT BUILD UP FULL DISCHARGE PRESSURE

For compressors with idle warm ---up controls, switch toggle to “run” for full operation.

Air Demand Is Too Great.

Check service lines for leaks or open valves.

Dirty Air Filter Check the filter indicator and change element if required.

Defective Pressure Regulator Check diaphragm and replace if necessary (kit available).

Defective Idle Warm ---up Control Replace control.

I am unable to do a phone call right now as well. The site auto generates those messages. Check and see if there any flash codes.

everything is analog no where to plug in or a bulb that would indicate that (flashes for faults
Mechanic: Dan, Technician replied 3 years ago

Actually this compressor does utilize flash codes. It doesn't display a number but you would count the flashes if there is a fault. Depending on the number of flashes, this will indicate what fault code exists.

where would I find he bulb for the flashes?
Customer reply replied 3 years ago
that is not the gauge panel. Mine only has air pressure, Hours, ignition and circuit breaker
Mechanic: Dan, Technician replied 3 years ago

Thanks for the photo. Look below that switch. I believe your warning indicator is in that blacked out area with the round part that looks like it pushed in a little. From the looks of it, there has been some modifications of that panel over the years. It is possible that the bulb is out or it doesn't work anymore.
