Hi All,

Replaced a dead alternator (Auto Shop tested it) in my 66 Plymouth, but unclear of what i see for voltage at the battery (the battery is brand new and charged to 12.5). I am used to newer cars where you see a decent charging voltage (13.5), here I see 12.2 at idle and the in-dash ammeter shows little change, but the voltage does go up when I rev the engine (12,3, 12.4)and the ammeter moves to the charging side, is this normal?

Thanks, BAM
