Bypass Internal Voltage Regulator Alternator

This is enough to destroy the car s battery and electrical system.

Bypass internal voltage regulator alternator.

The voltage regulator is built into the alternator on all chevys made from the 1980s to at least 2010. If the voltage regulator in the computer does not work you can add an external voltage regulator and then your battery will charge. 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. 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 other main connection on the alternator is the output terminal that charges the battery. It also controls electrical power to the vehicle s different electrical systems. Without a voltage regulator an alternator may put out up to 250 volts. Ecm not communicating with alternator s voltage regulator.

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. Battery is not charging. Without a regulator the battery would receive upwards of 30 volts of power while charging which would quickly damage or destroy.

A voltage regulator controls the alternator voltage output to maintain a preset charging voltage for the battery. Simply put the regulator restricts the amount of voltage being sent to the battery.
