Question about 1983 Ford Bronco

1 Answer

Shorting out somewhere!

I'm getting my Bronco ready for Moab Jeep Safari here at the begining of April.  I've put in a new battery, alternator, starter and starter solenoid.  Only problem is now, whenever I roll down the windows the radio kills and somehow the battery/alt is only pumping out 10-11 volts when it should be around 12.  I've never had the problem before.  What could it be?

    I wasn't sure if the '83 had the ex. voltage reg.  so that was another q you helped answer.  I also thank you for the FYI on volt reading.  I figured it needed to at least push 12 with everything off.  ALSO, I've taken the alt to 3 diff shops to have it tested.  Each test has proved the alt is great, pushing out 15 volts at every shop. So to the volt reg. I go! Thanks!

I believe that your vehicle has an external voltage regulator for the chargeing system.just FYI the spec on all vehicle chargeing systems when the vehicle is running should be 13.8-14.2 when checked with a volt meter.I would start by checking the voltage regulator.If it isnt external than your alt is bad.

My battery in my 1994 Safari Van keeps draining after being charged. What could be the cause of this? It's a brand new battery.


Either a shorting wire off a wiring loom somewhere in the electrics or a boot light or internal light not switching off.did you recently fit a new item to the vehicle as this could be part of the problem.

Headlight switch turns my Bronco off?!


Sounds like a weak connection somewhere close to the battery.
The alternator should be able to keep up with the extra electrical load not to mention the storage capacity of the battery. So if the headlights are killing power to the key switch, something is weak between the battery and the key.
Could be a corroded cable, connection at the solenoid, or in the fuse box.

I've been having a problem with my 2000


No.dont diconnect the negative or positive battery at all The alternator only produces 2 volts above battery voltage so a total of 14 volts. If you dont have a volt meter get a small screw driver be careful doing this if you can safely access the back of the alternator (without shorting anything out)in the midddle of the alternator will be magnetic. That will tell you its charging or better yet get a compass and put it at the battery positive terminal and it will swing that tell you its charging. You disconnect the negative the whole car shuts off you disconnect the positive the car stay running but produces high voltage and can damage the alternator itself

Wont start


Could be the diode pack on the alternator (or a short somewhere else). Disconnect the alternator to find out.

Put a new alternator in 2000 Jeep Grand Cherokee engine light on


well , the ECU runs the alternator. (DG wire "dark green")
the alternator field is controlled 100% by PCM reg , inside PCM.
so..... if the running engine has 13.3, to 15vdc the alt is working
if lower, its not. (rpm on engine 800 or more)

not scanning the PCM a the CEL glow, you missed the boat.
why not scan it. see why the PCM is upset (DTC errors stored)

see the 2 lower pins below , those go to PCM.
in theory if the field in the old BAD ALT, was shorted.
that could in fact, burn up the PCM regulator.
shorting outputs of PCM , does that in most cases.
im the poor sod that fixes PCM's.so....
