What voltage window is the Xtreme Charge Quick Battery Tester set at to determine Good and Bad Alternator reading?
Good – 13.8V to 14.7V, Bad – 14.7V – up Note: the Quick Battery tester is only a basic open circuit voltage meter designed to help determine if there may be a fault in the charging system – the “Bad” indicator light only lights as a result of a High voltage limit of 14.7V or higher – there is no low voltage indicator for a “Bad” reading.
