voltage regulator

Asked by Dec 16, 2015 at 03:24 PM about the 2005 Dodge Grand Caravan 4 Dr SE Passenger Van Extended

Question type: Maintenance & Repair

If pcm fails to regulate voltage, can I rig an external
regulator to bypass pcm. Would the car run and
would it throw any codes for emissions testing.

The best repair is always find and repair the problem. You may make things worse by trying to "southern engineer" something, especially when computers are involved.

Actually they make kits designed to do just this, bypass the ECM voltage regulator when it fails. Some links: https://alternatorparts.com/external-voltage-regulator-high-output-alternator-kit.html ("External Regulator Conversion Kit for Your Chrysler, Dodge, Jeep.
