New alternater & voltage reg - not charging

Don't know if you hurt it or not, but the regulator absolutely MUST be grounded to operate.

To "quick simplify" some of the test, do this:

Turn the key to "run" and use your meter or test lamp. Disconnect the green wire at the alternator but leave the blue hooked up. Probe both the blue and the unhooked terminal where you pulled the green off. You should show power on both. Ground exposed alternator terminal and start the engine. Watch the ammeter and see if it charges by bringing the RPM up some.
