High amp draw - diagnostic assistance

[BigIke]

I've burned up two alternators pretty quickly. After the last install, I put the original pulley on (larger thinking my constant 7000 rpm adventures were killing alts...) but the voltage was very low at idle with AC on.

When The Car is hot and both fans are on high speed, the voltage is low (12vdc)when cold and the AC is on the voltage drop is the same or a little lower.

Amp draw is 15-17 on both fans, and around 20 on the AC blower motor.

Recon I need cooling fan motors or a new blower motor?

The blower doesn't feel like it blows as hard as it once did...

Thanks Jay.

PS. Haven't posted in awhile but I'm still beating the snot out of this thing, and loving every minute!!!
