Re: Possible Alternator short

No you should always have battery voltage at the alternator connected or not. You need around 14.7 volts there with the engine running (depending on the battery state of charge, you probably would have more like 14 volts.).
There is no need to remove the charge wire to check voltage, just check it on the alternator, if you didn't have B+ that would mean you have an open wire or open fusible link.
