Noticed the battery light illuminated on my instrument cluster yesterday.
2014 f250 battery light.
If the battery light comes on while the engine is running and the vehicle is being driven this indicates a problem with the charging system.
Drive a while stop the truck turn it off etc.
When you first turn on your car with the engine off the battery light will illuminate and this is normal.
Turn off everything that draws power.
Batteries are 2 year old napa legends and tested.
Ok i have 14 04 volts at the batteries with the engine running but my battery light is on.
I have a 2012 6 7 at 50 000 miles with the single heavy duty alternator.
The contact owns a 2014 ford f 250.
1999 to 2016 super duty battery light on but alternator is charging.
Shows good batteries and good charging.
The battery light is on but the voltmeter says 13 5 to 14 5 volts depending on the engine revs.
Equip cars trucks suvs with 2014 ford f250 super duty battery from autozone.
Is there something internal to.
The vehicle was taken to a dealer where it was diagnosed that the battery failed.
The next day very same thing.
Part 1 of 3.
My mechanic says that the alternator must be charging but why is the light on.
I had the alternator checked off the engine and on the engine and it tests good.
The contact stated that the battery warning light illuminated.
When engine is off the volts drop to about 12.
We have the best products at the right price.
Voltage is at 13 5 with battery light on drive and do what i need to get to where i m going shut the truck off then get back in and turn it on 12 3 12 5v max.
Turn the truck back on then getting 12 5v won t go above that and the battery light remains on.
