im seeing a voltage drop when comming to a stop. 14v to 12v. is this normal? if not what can cause this? bad grounds? i have also noticed my headlights dimming when i press the brake pedal.
sounds like your alternator is starting to crap out.
it will progressively get worse.
does the car sputter at all? one sign of a dying alternator is sputtering (not enough juice to charge the coils)
More importantly, Does it only happen when ur on the breaks.
- like from a stand still doesn the voltage drop to 12
- is this only when driving? is it constent
could be something as simple as an idle issue
i went thru this as well ended up being a vac leak and + a bad ground.
