Hey man, let us know what you find.
If you place the meter leads across the battery posts, everything off, the generic spec for a full charge is around 12.6 volts. Take the same reading with engine running. The second reading should be higher than the first, if the charging system is working.
You an leave the leads hooked up during cranking, If the reading drops much below 9 volts, you need to get battery charged. Also, make sure battery connections are all clean and tight on both ends.
Yes, on some year--makes and models, if the battery voltage is lost, the vehicle can go into theft lock.
