Bypass Internal Voltage Regulator Alternator

If the voltage regulator in the computer does not work you can add an external voltage regulator and then your battery will charge.

Bypass internal voltage regulator alternator.

The voltage regulator for the alternator is in the computer. Simply put the regulator restricts the amount of voltage being sent to the battery. 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 regulator the battery would receive upwards of 30 volts of power while charging which would quickly damage or destroy.

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. Ecm not communicating with alternator s voltage regulator. This is enough to destroy the car s battery and electrical system.

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. Battery is not charging. A voltage regulator controls the alternator voltage output to maintain a preset charging voltage for the battery. The other main connection on the alternator is the output terminal that charges the battery.

Without a voltage regulator an alternator may put out up to 250 volts. The original 1960 s gm alternator employs an external voltage regulator.
