compressor won't turn on

My battery died the other day so I took it out of my truck and re-charged it. After hooking my battery back up the compressor won't turn on. Looked at all the fuses and every single on is fine. Anyone have an idea what may have happened?

are your relay(s) clicking?? if they aren't get a test light & check all the power wires leading to the compressor(s)

The switches have power its just that i cant get the compressor to kick on for some reason. Before the battery died everything was working just fine. I find it strange that after taking the battery out and charging it that the compressor decides not to turn on when all was good just a day before.

check your relays. pressure switch.

run a direct lead of power to the compressor see if it kicks on without the relays and pressure switch

did you reconnect the fuse at the battery?

yes the fuse at the battery is hooked up. the only thing i can think of is maybe the relay solenoid is not sending the power to the compressor for some reason.

have you bench tested the compressor?

try your compressor without the pressur swith.

might need to check you ground i had the problem before on my truck
