The engine control module acts as the voltage regulator.
A voltage regulator module (VMR)
The voltage regulator is NOT built in the alternator, it is part of the ECM, that is the Engine Control Module. The module (computer) monitors the charging system and signals the alternator how much voltage to send it to keep the system working properly. the voltage regulator is built in to the alternator
internal to the engine computerThe voltage regulator on a 2000 Chrysler Voyager is located within the Powertrain Control Module. If you want to replace the voltage regulator, you have to replace the PCM.
Answer It's built into the powertrain control module
The voltage regulator is controlled by the powertrain control module and it is located on the passenger side firewall on most Dodge 3500 diesel. This is a problem that some people fix by installing an external voltage regulator.
Built into rear of alt
It means the charging system voltage (is) too low, Check the alternator and the voltage regulator. The voltage regulator is a part of the powertrain control module or PCM.
No. The engine's control module regulates the voltage. No other regulator is necessary. A very expensive repair if it's faulty though.
Inside the rear of the alternator no it is not, it is in the powertrain control module The engine computer is also the regulator.
The "voltage regulator" was a function controlled by the logic module in the 1987 SC. I think this was the case for 1985 as well. The logic module is located in the passenger side kick panel. A common problem with these cars was this function of the logic module being "fried" by a poor ground.
