What I Drive
2010 Fiesta 1,6

Hello. Every 1-2 weeks I need to charge the battery. It charges ok. This morning it was fully charged,.and when idling it showed 13,6v. After som driving and parked a few hours it showed 12,6 v engine off, and 13,25v at idle. When I turned on heater fan full and defrost, voltage dropped to 12,6, before climbing to 13,1v.

Believe there is a problem with the alternator/ charging system. Have no alarms in the dash indicating any faults. Does anyone know if it has an external voltage regulator, or can give any tips on how to dig deeper?

2010 1,6 diesel 95hp.
