I had a brainstorm, duh. I put the multimeter on the + and - of the voltmeter and started the car up. The multimeter read about 14.3 at average, and 14.4 max.

I think I'm in good shape. Just have a lot of wiring to clean up as I had to pull out the dash cluster and unravel all of my looms... Oh, and a voltmeter to replace
