Voltage Regulator Testing?

Last night I connected the 12v ign wire at the VR and the field wire at the voltage regulator. When I brought the RPMs up, voltage at the battery went up past 15. So I guess that means the alternator is working.

I also checked the battery voltage at idle which was 12.8. When I brought the rpms up, it went up to 14.5. Looks like everything is working, right?

Maybe there's a draw somewhere in the system.
