Battery Light ON... Drains while running
A few days ago, battery light came ON... Then pretty dramatic draw on Battery Gauge became evident.
Had Alternator checked... tested bad Voltage regulator which is inside the Alternator. Changed out alternator and belt... charged drained battery and fired it up... battery lite still ON and truck acts like it is running off the battery alone. Had NEW alternator tested and it passed.
Still heavy drain on battery when in operation.
Check the electrical plugs at the alternator. They're notorious, on Ford Products from this era, to burn out. HTH. -Jim
Any luck fixing it I'm having the same problem right now I have a 2007 Ford F-150 Harley Davidson it's draining the battery until it shuts completely off
