New PCM controlled voltage regulator
The alternator first introduced in 2003 police cruisers is now standard in civilian crown vics
However, a larger diameter pulley is installed on this model to lower accessory belt noise
Some parts catalogs also list this alternator as being different than the 2003 cvpi one because of a chip inside the voltage regulator that's supplied by a different vendor

Note: Some aftermarket re-manufacturers of alternators may install a regular pulley instead of a clutched pulley to lower cost.

There is also a clutched 6g alternator used in some of the 2005-2006 lincoln navigators and 2005-2006 ford expeditions. Two different alternator models were used in these vehicles, so finding a pre-owned "large case" clutched model that you're after can be difficult because there are a lot of "small case" unclutched models out there. A very limited number of 2003-2004 navigators/expeditions also will have clutched 6g alternators in them. But no clutched alternators were factory installed by ford in the 03-04 navigators/expeditions. Instead, ford issued a technical service bulletin (tsb) to their ford dealerships advising them to install a clutched alternator model if customers came in with certain electrical problems. Do note that the 03-06 navigator/expediton alternators with the clutch will have a 60mm pulley which is kind of large for a crownvic. The 03-04 navigator/expediton alternator (WAI 1-2533-31FD) has an I-FR-A voltage regulator that should work in the 1992-2002 crownvics. The 05-06 navigator/expediton alternator (WAI 1-2668-31FD) has an  FR-SIG-A voltage regulator that should work in the 2003-2010 crownvics.

Note: The same electrical connector is used on the 1998+ crownvic 6G alternator regulator as on the 1995+ crownvic brake master cylinder reservoir fluid level sensor. But the master cylinder reservoir sensor has a ~20AWG wire on pin 3 rather than the ~14AWG wire that you need for a 6G alternator.

Note: The engine appearance cover may need to be replaced with a different unit after a different alternator bracket is installed. The appearance cover serves no mechanical purpose and is cosmetic only. Many police departments remove this cover as soon as their cruisers are placed into service, and never reinstall it.

Note: The alternator upper bracket in the 1998+ cars serves two purposes. It's a crash bracket to protect the fuel rail in a really high energy frontal collision. It also holds the alternator stationary so the bottom mounting bolts aren't overloaded. The normal mounting load on this part is very minimal, and some people have run their crownvics without this bracket installed for short periods of time without a problem. Some have even run their cars for years without the top alternator bracket installed, but others have had the bottom two bolts break leaving them stranded on the side of the road without any front engine drive accessories rotating anymore. Do note that without the waterpump spinning, engine coolant will really heatup and your engine could be damaged beyond economic repair or seize up all together.

Here is a graph from the 2003 police interceptor modifers guide showing a graph of the 6G alternator shaft speed versus alternator output. Keep in mind that the alternator is overdriven and spins faster than the engine crankshaft.



Here is a graph from the 2004 police interceptor modifers guide showing a graph of the 190amp mitsubishi alternator shaft speed versus alternator output. Keep in mind that the alternator is overdriven and spins faster than the engine crankshaft.
