Bypass Internal Voltage Regulator Alternator

It also controls electrical power to the vehicle s different electrical systems.

Bypass internal voltage regulator alternator.

The voltage regulator is built into the alternator on all chevys made from the 1980s to at least 2010. The voltage regulator driver is a chip built into the dodge pcm and can only be fixed by 3 methods 1 replace pcm 2 bypass internal pcm voltage regulator with an external one however this will have a check engine light on and a code and the battery guage. The original 1960 s gm alternator employs an external voltage regulator. Since 1987 for dodge and chrysler and 1991 for jeep vehicles have external regulator alternators that are controlled by the alternator voltage control module inside the engine control unit ecu computer.

Without a voltage regulator an alternator may put out up to 250 volts. Battery is not charging. 04 30 11 10 55 pm post 2084285 i ve posted a question on my charging problems in another thread and got some good answers that led to ordering a new alternator now i m thinking about changing to a internal regulator style instead of the external type i m having now mainly because my speedshop carries the internals in stock and the external one is on order and i want to fix it a s a p. The voltage regulator for the alternator is in the computer.

Simply put the regulator restricts the amount of voltage being sent to the battery. If the voltage regulator in the computer does not work you can add an external voltage regulator and then your battery will charge. This alternator 10 dn uses a flat two prong connection at the back of the alternator. This is often called the ecc ecm eec or pcm.

This is enough to destroy the car s battery and electrical system. A voltage regulator controls the alternator voltage output to maintain a preset charging voltage for the battery.
