The voltage regulator is in the PCM. If there is a problem with it, the PCM has to be replaced.

Battery goes dead while driving ck out put on alt ok at the time replaced computer same thing also it may start working ck all elect connection 2000 4x4 jeep cherokee


Hello. If your battery is not charging while driving, often it is due to low or bad voltage from your voltage regulator, which is also in the Alternator usually on these vehicles. Your engine has been running off the battery only and draining it, not using the alternator's power. Here are some things to look for and a question for clarification:

If you actually replaced the alternator already your regulator should be good. But to clarify your problem report, did you replace the alternator or only check it? It may take several checks while truck is running to catch the problem. If you have not done so already you will need to verify that voltage (13.9 volts or more) is actually reaching right to your battery. 12Volts will not be enough, that means something is wrong and is just battery volts. Please do this test while your Jeep is running, with lights on. DC volts across the battery need to be about 14 Volts while all is on. If you don't get that either the Alternator/VR is bad OR bad connection to it.

My 93 jeep grand cherokee starts but it draws a lot of juice then it dies. So far I have replaced the fuel pump, starter, coil, ignition, and alternator. Any suggestions?


Based on what you noted, your system is not drawing too much, it is overcharging. Determine if you have an external regulator in your system (depends on alt. make and alternator design) Many of the Jeep systems have the voltage regulator as an integral part of the main computer. Likely it has failed. Also make sure that the charging system is properly grounded and the battery is fully charged and can undergo a load test without substantial voltage drop. If it cannot, it will over-work the alternator.

2004 Jeep Grand Cherokee won't turn over.


As long as you can jiggle the battery cable and it helps, you have identified a problem in that area. The solution would be if you have side mounts use a small wire bush or old throw away tooth brush with about a cup of water mixed with a table spoon or so of baking soda, and clean all the corrosion off the terminal connectors.( The part that connects to the battery ) If post, clean the inside of the post connector by using a battery terminal cleaning tool sold at the parts store for a couple of dollars. As long as your terminals are dirty or lose the alternator cannot get the electrical charge to the battery and your battery will go dead and or get very Durr! Ruhh! low. Oh yea after it gets dark and you turn your lights on with the battery terminals lose or corroded to the point they don't let the alternator charge your battery, the battery will use all the stored voltage very quickly and the lights will get dim and when you stop your engine will turn off and probably want start back up with out a boost from a good sumaritan.even though the battery and the alternator are like new.

Sounds like an intermittent bad voltage regulator inside the alternator,although it could possibly be a loose wiring conecton.You are doing good by checking system voltage at the battery with the engine running.Check for clean tight electrical connections at the battery and at the alternator.Also check grounds.
