Today i turned on compressors to fill tanks and raise the  truck up out of all 6 viair 480s there seems to be only three  working which really sucks. so should i just  replace the non working 480's or buy  air zenith compressors  or find someone that can put an engine driven on my truck  which is  a 2003 ford f-150 with  5.4 liter engine.  all ideas or suggestions  please  help

if 3 of them quit working at the exact same time, I'd suggest double checking that it isn't simply a wiring issue and that the compressors are completely fine.  Don't know what would cause 3 seperate compressors to fail simultaneously

have you done any electrical inspection yet?  Made sure the relays are clicking over?  Made sure that all compressors are receiving power?  I would also suggest all fuses, make sure that they haven't simply blown in a manner which still allows a small amount of voltage to cross which can sometimes trick a meter.

I would switch to the 80 amp relays that Suicidedoors sells, run 1 relay for 2 compressors use 4 g wire
