So here i was out in the Beerwah forest and came across a compressor. Its a NipponDenso 6P127A which i have found out is a toyota corolla air con compressor. How can i test if its still alive?? I just want to run it without an air tank for now and only use it to inflate tyres as needed. Just have an incab switch to turn it on when i need it. Maybe upgrade the system later for full endless air.
