If you are talking alternator regulator then find the existing unit and change it out with a new unit. Some alternators have the regulator as part of the brush set in the back of the alternator. With an income earning vehicle ,although it may be expensive to take it to an accredited truck auto electrician the cost of the job will be far less than the income earned by getting the vehicle back on the road in the shortest possible time.

This is not rare. Possibly bad "new" alternator or bad "new" regulator. Have seen it happen many times. :-)

2003 freightliner mt45 battery indicator stays on.


Put a volt meter across the battery and if it reads less than 13 volts then it has a problem. The system should be 13.5-14.5dc..... 15 volt max. If it reads low only that idle, the engine may be idling to low, the regulator is bad, the belt is slipping, or the system has to great a load on it while idling(to many lights and electronics). If it comes up over 13.5volts when the engine is revved up then the regulator/slipping belt/ or load is most likely the problem. If it does not come up to the voltages listed above then the regulator/alternator are faulty.

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.

Do wires go from alt to reg


Can't remember if 1984 had a separate regulator. If the engine has a computer that's where the regulator willl be. If you do have a separate regulator it will have 2 wires. The green wire goes to the alternator field circuit. The other field circuit wire gets ignition on voltage as does the center terminal on the regulator, either a red or blue wire, probably blue.

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'

1984 honda prelude battery on


Do u have the carbureted or fuel injected model? (both were available that year) The carb. model has a separate voltage regulator which is mounted on the right front shock tower. The fuel injected model is inside the alternator, under the end cover.
Have the alt. tested before u purchase a new one to make sure that's the problem. Most parts stores will check it for free. Be sure to disconnect the neg. battery cable before u start to remove it. Let me know how u make out. Curt
