Hi guys, i'm having issue's with my Mondeo ST220, anyone know what volts the battery
should put out 1. with ignition off 2. at idle.

fitted a new alternator and new silver calcium battery but my battery light is still on,
checked my battery and with engine off its 12.4v, at idle its 12.1v and if i put lights on it
drops to 11.7v.

 

Alternator is not charging as it should really be high 13's+ at idle without load. 12.4 with everything off is fine tho so battery is probably alreet

 

cheers mate.
