Hi

The voltage regulator is usually built into the alternator.

Very best regards

Does jeep nwrangler (1998) 4.o litre with air have a voltage reulator that if bad would stop alternator from putting charge into battery? and where is voltage regulator located?


The voltage regulator it in the ECM.What you need to do is go to the basic which can be overlooked like is the Alternator fuse burnt open that will require a new fuse, how is the battery terminal connection? You need to check that,Or how is the calbe from the alternator to the Battery is the connection in good shape? Those you need to check you mainly need a voltmeter to do this but a good visual inspection can get results,

84 dodge ram battery wont charge


If it has a voltage regulator it should get power from the key switch to the field wire on the regulator.
You should have battery voltage at the big wire on the alternator with the key off.
I would check for a fuseable link between the alternator and the battery first.

CHARGING LIGHT STAYING ON AND ALTERNATOR CHARGING TO 18 VOLTS OFF AND ON


The light will come on if the system is over charging. No system I know of charges at 18 volts. That is way too much. You need to have the alternator checked out. Most system charge at 14.5 to 15 volts at the most. You will burn out something major if not fixed. you can go by most auto part stores and they will check it out for free.

Charge light was on and alternator was overcharging. had alt. rebuilt and new voltage reguator, not charging now. only getting 2 to 3 volts are the charge fuse beside battery. new voltage reg is electronic...


There is a fuse under the dash that is the same one that operates the fuel gauge, if it blows the alternator wont charge. If the fuses are good I would take the alternator off and get it tested. Hopefully the rebuilder will warranty it. I would also make sure the new regulator is compatible with the old type regulator system. Most large auto parts stores can test alternators, and they normally do it free.

Is there a wirer that runs from the alternator to the battery on a 1984 mercury capri. The car is not charging the battery and I replaced all the battery and starter cables


From the alternator the AC is converted to DC and regulated so as to make a controlled charging at all levels of the alternator RPM when the engine revs. This is to keep the high voltage of AC to DC from damaging the battery and so the regulator/controller is an important part.
So you must first check your alternator voltage/current , then the controller regulator and the battery voltage change can be seen with a voltmeter across it. Also the currrent to the battery can a be checked with an ammeter in parallel.
So check these tips and comment.

I have a 1984 ford f150 with a new voltage regulator and perfectly working alternator but it charges at over 16 volts


a low battery in you meter could cause a higher reading. I've seen this before. Other than that the regulator is not working perfectly if its over charging or if you have a battery that will not hold a charge'

Im having trouble with my 84 ford econoline 6cylinders voltage regulator diagram please help is living my batterries smelling realy bad i check the alternator and is good


It souds like your system is overcharging..... check to make sure the charging system is charging between 13.5volts and 15.3volts at 3000rpms if more than that the voltage regulator is defective and needs replacement,if this situation occurred and the van was used for an extended period then you may have cooked the battery too... It will not be long that it may go bad.

Charging system


If you have changed the alternator and regulator, about all that could be left would either be a short circuit that is draining current away, or a bad ignition warning light bulb. That is because the power to energize the field of the alternator, comes through this dash bulb.
