Question about Toyota Cars & Trucks
'02 Camry,V6. Charging circuitry. Parts store pulled a code (Voltage reg bad. Where is the VR , what should aternator and VR be putting out. Thx
Voltage regulators are inside the alternator now.. they are built in..operating voltage should be 14.5-16..depending on load requirements most tool shops have a battery tester that checks load and battery condition as well as charging of the alternator.. these go for about 25-50 bucks I use mine all the time..

Are the connections really dirty at the voltage regulator? These tend to get corrosion on them and cause weird charging system issues. Also make sure the ground is good on the regulator.

SOURCE: Alternator or Voltage regulator
if you can carefully put a metal wrench on the rotating pulley of the alternator and felt a magnetism attracting the metal wrench, then your alternator is charging. if there is no magnetism, then the alternator is not charging...
another test is to measure the voltage on the small wires that went in to the alternator that says "F" for field, it should measure battery voltage...that is the voltage from the regulator..that means your regulator is working...but the altrntor is not..
without that battery voltage, then the regulator is he culprit...
pls be carefull...
hope i was able to solve ur problem..
pls rate me.. tnx, drcool..

SOURCE: overcharging alternator
This year it is not supposed to be in the computer,look on the firewall in the middle,I believe it is flat,and has a three wire connector,but only two wires in the plug,see if you can find it.

The voltage is regulated by the pcm (power control module ) on the truck. You cannot make any adjustments, removed or tampered with in any way to the pcm. Only a dodge dealer can check it out to see what the problem is with the pcm. Hope this will help you.
