could be low battery or loose connections
Check battery connections, check alternator out put. Exc.
either alternator or wrong size battery
Yes it will
Normally it means the alternator is defective.
Why would battery light come on then go off
I had same problem with my 2001 Isuzu rodeo sport with 53K miles.......and just put a new battery in and presto, no more abs light.....I think if your battery is weak (does the car have any problems starting and is electrical good?), it will trigger the abs light.....it did on mine.
If it is undercharging the battery yes, but if it is overcharging the battery no in most instances. If it fails completely the light will come on.
what causes the battery light to on a 2005 ford expedition to come on?
Battery
It could
Does your underhood light come on when you open the hood ? If not , it sounds like a dead battery or poor cable connection to the battery
Your battery is probably dying
