air zenith compressor

i have 2 air zeniths,but i have not hooked them up yet,i was just wondering if i need a bigger alternator,i already have 1 yellow top.this is for my fulsize chevy c-10....please help.

you should be okay, they dont draw to much but a bigger alternator can never hurt.

2 work fine on a 105 amp alt.

whats the amps on a stock alternator on fullsize chevy c10.

depends on options, year and if it was ever changed.

its a stock 1,its a 86
