Question:
Error shows under current #9. What is this
asked by: Ron W
Expert Reply:
The error code #9 under current is saying your Air Lift WirelessAIR Compressor System # AL74000 is not getting the power it needs from the battery to run. First you will want to check battery and ground connections to ensure they are not loose or corroded. Next check compressor connections, again looking for loose or corroded connections. You can also disconnect the compressor and test it on the bench using a 12 volt battery. Finally, remove and reinstall the 15A fuse to reset the fault.

I checked all connections and removed fuse and reinstalled. Still get same message #9 under current. Getting power to the compressor because when I try to increase the air pressure all I get is a quick puff then nothing. Only thing I have not done is remove compressor and try running with battery.
