Have a Merc Scorpion 5.7L - replaced batteries 3 seasons ago....charged them both prior to this season, started fine but when in idle the gauge is showing a 'drain' dipping below 12v - when running at normal speed/revs...gauge pops back up to showing charging....but even if run for a length of time as soon as it goes into idle the gauge shows a drain....looking for advice...is it alternator?
