Battery light stays on and battery drains while driving
I have a 2002 ford F150 and the alternator went out changed it but the battery
light stayed on and the battery drained, so I replaced the battery and PCM and
battery cables and selenoid still have the same problem. It shows that the
alternator is only putting out 11.46 volts when hooked up but puts out 14 volts
when not hooked up. What can cause this issue?
Try your altinator jump start your truck and while its running pull positive battery cable off of battery if it keeps running its something else if it dies there's your problem
