Bypass Internal Voltage Regulator Alternator

This is often called the ecc ecm eec or pcm.

Bypass internal voltage regulator alternator.

Simply put the regulator restricts the amount of voltage being sent to the battery. 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.

Ecm not communicating with alternator s voltage regulator. This is enough to destroy the car s battery and electrical system. Battery is not charging. This alternator 10 dn uses a flat two prong connection at the back of the alternator.

If the voltage regulator in the computer does not work you can add an external voltage regulator and then your battery will charge. The original 1960 s gm alternator employs an external voltage regulator. It also controls electrical power to the vehicle s different electrical systems. 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 voltage regulator for the alternator is in the computer. Without a voltage regulator an alternator may put out up to 250 volts.
