1993 ranger charging problems

The regulator is internal. It was replaced as a unit with the alternator. I also had the new alternator tested and it checked out good.

    Battery is new, it turned out to be a bad voltage regulator on the NEW alternator.

What could be draining a brand new battery along with having a brand new alternator?


the alternator is not charging
problems include incorrect alternator ( internal voltage regulated as against external voltage regulated )
blown rectifier plate ( charing with ac current instead of DC)
drive belt tension
best have it checked by an accredited auto electrician

Hi Closet, I think the problem will be with the voltage regulator or a defective alternator. I believe it will be easier to fit a service exchange unit. That will mean removing the alternator from the vehicle. Remove the keys from the ignition. I believe its a good idea to make sketches all the way through the procedure, that way you'll know what goes where. Disconnect the battery and remove the negative. Loosen the alternator tensioner until the belt can be removed. Disconnect the electrical connections. Remove the through bolt under the alternator and then remove the top bolt. Remove the alternator from the bracket. Fitting is the reverse procedure. Make sure the belt is correctly tightened, and you should be away. Regards Johngee10

Hey i have a 1993 ford bronco four wheel drive with the 5.8 engine. I have had the alternator checked and its good and the battery is good but it will not charge. Its running on just the battery, Do you...


You need to check your alternator circuits. If the alternator itself tests good (I am assuming it was removed from the vehicle and taken to a parts store for testing) then the only thing left are the alternator circuits themselves. The large BLACK/ORANGE wire needs to have direct connection to the battery. This connection needs to be clean and tight with little or no resistance....This needs to be checked with an ohm-meter to verify. The rest of the circuits depend on what your vehicle is equipped with. 1993 Ford Broncos were originally equipped with two different charging systems. One had an integral regulator (regulator built into the alternator) and an external regulator. (voltage regulator mounted on the fender, separate from the alternator.) If you have the external regulator, that is what I would suspect as the cause of your problem. If you have the internal regulator, then I would check for battery voltage on the two BLACK/ORANGE wires and the YELLOW/WHITE wire at all times, and the LIGHT GREEN/RED wire should have battery voltage only with the key in the ON position.

The voltage regulator is built into the Alternator. Take out the Alternator and have it
tested at your local Auto Parts store (they all do it free). This will tell you if the Alternator
is your problem or if you need to check elsewhere.

1993 dodge caravan, over charging, replace the alternator, was tested and told it was bad, still over charging. Was told that the computer controls the voltage output, do I replace the computer system now,...


The computer has NOTHING to do with the alternator output.
The alternator is self regulating, with diodes, and rectifiers.
If the alternator is over charging it is because your battery is not accepting the charge, so the charger works harder and produces more to charge it, up to a point.
Was the alternator that you installed new or rebuilt ?
It could be another bad alternator.
Please let me know.
