Charging pronlem

[Ouchdog]

On my way to work yesterday i noticed that my battery light came on on my 90 ZR1 i put a multimeter on it and only had 10.50 volts with it running. I assume that the alternator is shot so i ordered one. I am going to replace the battery also. My question is can i replace the alternator without pulling the plenum and just pull the throttle body extention off. I dont think i have what it takes to pull the plenum you guys make it sound pretty hard.

thanks

It can be done w/o taking off the plenum but takes some patience on one of the bolts.

Welcome onto the boards there.

Was the BATTERY at 10.5 volts? Or was the Field Output on the alternator at 10.5 volts?
