Why Alternator Health Matters on Crown Vics
Once the engine is running, the alternator becomes the primary electrical power source for:
-
Engine management and ignition
-
Cooling fans and HVAC blowers
-
Lighting, radios, and auxiliary electronics
-
Charging and maintaining the battery
When alternator output drops, the battery tries to cover the gap—briefly—and then fails early. Symptoms include:
-
Repeated dead batteries
-
Flickering headlights or dash lights
-
Charging system warnings
-
Random electrical glitches
Replacing the alternator fixes the root cause, not the symptom.

The mechanic shop just told me my brand new alternator doesn’t charge at idle! Only When you get to 2,000 rpms it starts charging! And now since It has been over a month of me trying to figure out why my car doesn’t stay running, I can’t retrun this defective Alternator!
Sam Brunner –
I saved hundreds in comparison to purchasing this from any auto parts store, and it fit and works perfectly!

DO NOT AND I MEAN DO NOT BUY THIS ALTERNATOR, YOU MAY GET 2 MONTHS AND IT DO NOT CHARGE AT IDLING SPEED AT ALL AND THAT WAS BRAND NEW, I BIT THE BULLET AND DELT WITH IT BUT IT TOTALLY WENT OUT, AND AFTER TRYING TO RETURN AFTER 2 MONTHS…GOOD LUCK

Had to have the regulator replaced right out of the box I put the alternator on and at idle it would barely charge and I would give it gas and it would spike real high took it to the alternator repair shop and had a new regulator installed and works perfect now but you should not have to do this with a brand new alternator it was just easier for me to have it fixed than to send it back and it take a week to get a new one

Would not charge, wasted time installing it and then having to remove and replace it. Of course I chose another brand.
