Inside the alternator
Try changing the battery.
Have the battery checked out. It may have a dead cell and not holding a charge,
?ignition control module/pickup
Check your charge fuse (7.5 A)at relay block no. 2. (passenger side engine compartment.)
sounds like your gauge is broken or there is a short in wiring
I have a 2.0 1995 Mercury mystique the battery charge light was on no output on old alternator. Replaced alternator No output from new alternator "charge light out" (wiggle test wires& re-check wires) at alternator *still no output* is there a fuse that could be the problem or just another bad alternator... I would check the alternator plug before getting another alternator, it may be bad. And is a lot cheaper to replace.
I'm having the same problem. The cause of the nackered battery and dead alternator could be a faulty charge relay. Try replacing this and see if the light goes out..
i have changed the alternator and voltage regulator and it still wont charge ; 84 Plymouth reliant
White An blue wire from ecm will ground causing alt to not charge just cut w/b wire going to alt harness it will solve your problem
check for proper belt tension, check all of your connections from the alternator and the ones on the batteryif everything check out have the battery tested, if none of this works feel free to e-mail me
As long as the ignition switch is off, it will not damage the alternator.
