Welcome aboard Brad!! Sounds like a decent enough deal to me! As mentioned the issue could be the connector. A great replacement battery is the DEKA brand which is an AGM, and one of our members, Skydoc 17, Earl, is a distributer and gives us members a great price. As mentioned the stator is relatively easy to replace. There are good aftermarket R/R's available as well. There is plenty of technical info on this site as well as many very helpful prople.
To test the stator, disconnect the connector and with an ohmeter yo should see a low resistancfe between any two wire combinations. Each wire to ground should see infinity ohms (open). Switch the meter to AC volts and start the bike. You should see around 40 volts AC between any combination of 2 wires, and they should all be very close in value. If not the stator is bad (like you saw 34V, 21V, 33V).
