Hello Jick

First thing in the morning
with engine off
- headlight off 12.4 Volts
- headlight on 12.0 volts

with engine on
- headlight off 14.4 volts
- headlight on 14.4 volts
- headlight on, aircon on 14.4 volts



After 1 hour driving
with engine on
- headlight off 14.0 volts
- headlight on 12.9 volts
- headlight on, aircon on 12.5 volts

with engine off
-headlight off 12.6 volts
- headlight on 12.2 volts


Are the numbers healthy ?

Thanks in advance.

kikoteng,
it depends, what was the voltage with engine at rest? what was the voltage with the engine running? what was the voltage with the engine running and loaded with headlights? publish your numbers please.
