Clicking on any of the numbers in the Lester KwikFinder table column will show pictures of the alternator model in question

Notes:

• PCM regulator = White plug
  Voltage Sense Regulator = Grey plug
• I/R = Internally Regulated
  I/F = Internal Fan
• All crown vic alternators are clockwise (CW) rotation.
• It is possible to swap later 96-97 output stud onto earlier 92-95 alternator or vise-versa. The back cover of alternator must be removed to do this first. This is an easy job on a new alternator that has never been installed on a car. But it could be challenging on a "pre-owned" alternator that is corroded. Some documentation on this project is avaliable by clicking here.
• There is a unique regulator connector used on 1993-1995 police interceptors. One can modify the vehicles harness to use a generic 3G plug if desired.
• Many other ford vehicles use a 3g alternator that will work in a crown vic including: ford expedition, lincoln navigator, e-series van, f150 pickup, cougar, thunderbird 4.6L 5.4L. But do note that the pulley on a truck will generally be 8 groove and on a car 6 groove.
• The same size 12AWG fuselinks are used on the wire which links the alternator output stud to the battery on all 95 amp, 110 amp, and 130 amp alternator models. However, the 190 amp mitsubishi alternator uses 10AWG fuselinks rather than 12AWG fuselinks. Do not bypass the fuselinks in this harness with straight wire as these protect against fire if the alternator output diodes ever short to ground.
• Engine idle speed is very important for charging system output at idle. Police Powertrain Control Modules (PCM's) usually idle somewhere in the 800RPM - 1000RPM range. Civilian idle is often in the 500RPM - 600 RPM range. Don't set idle speed too high or the car could lurch forward when the gear selector is placed into drive.
• The pulley on the alternator is also important to charging ability. A smaller pulley makes the alternator spin faster per given engine crankshaft rotation. But the smaller pulley will also slip more during big crankshaft rotation speed transistions and also more when driving in wet weather. In many model years, police vehicles recieved smaller alternator pulleys than their civilian counterparts for increased charging ability at engine idle.
• If you're running an aftermarket 200 amp high output alternator, make sure to upgrade to either 2AWG or 4AWG wire linking the alternator output stud to the battery. Include properly size fuses or fuselinks inline too.
• The 200 amp Mitsubishi alternators used in 2004+ police cruisers have a one-way clutch on the pulley. This minimizes belt chirp on hard acceleration, but unfortunately the over-running clutch often has a shorter lifespan than the remainder of the alternator parts.
• The 2003 crown vic police cruisers can be upgraded to the 200amp mitsubishi alternator with kit 4W7Z-10346-AD (GL-667) according to TSB 04-21-23. If you already have a spare 2004+ alternator in your possession, there is also a seperate 3W7Z-14A411-DA jumper harness avaliable to install an 04' cvpi alternator in an 03' cvpi.
• DB Electrical sells aftermarket high output chrome plated 3g, 4g, and 6g alternators avaliable for the crownvic. This company also sells on ebay under the username "dbelectrical".
  
• A pneumatic air impact wrench will be needed to change pulleys on an alternator. An electric impact gun can also work for this job.
• "Pre-Owned" alternators from wrecked salvage yard vehicles generally work, but an unknown amount of life remains in them. "Pre-Owned" salvage yard alternators from junk cars that people scrapped because they didn't want to pay to have them repaired often work too because few people will junk a car over a minor repair like a $200 alternator. Something major like a $2000 transmission job is often a different story on an older high-mileage car though. Do note that alternators sometimes "go bad" while sitting outside exposed to the elements in the salvage yard due to corrosion. If the pulley of an alternator doesn't turn freely with your hands, the alternator is probably rust locked internally. Many salvage yards store their alternators inside enclosed buildings instead of leaving them "on the car" for this reason.

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

Regulator Plugs:

Part Number	Comments
WPT-118 1U2Z-14S411-TA	Ford Regulator connector used on Ford 6G alternators and also the Mitsubishi alternator factory installed in 2004+ police cruisers.
WPT-119 1U2Z-14S411-UA	Ford Regulator connector used on both Ford 3G and Ford 4G alternators this regulator connector is also used in the legacy "box body" crown vics with the 2G alternator
WPT-851 5U2Z-14S411-SA	Ford Single cavity male connector used on Ford 3G alternators
Napa ECH-EC261	Aftermarket regulator connector for Ford 6G alternators
WAI 46-2802 Transpo WAA-794	Aftermarket regulator connector for Ford 2G/3G/4G alternators
Transpo WAA-600	Aftermarket regulator connector for Ford 6G alternators
WAI 46-2804	Aftermarket 3G Repair Harness - Stator Terminal

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. This is convienent if you're looking for a "pre-owned" 6g alternator wiring pigtail from a salvage yard because the alternator wiring is often missing from junkyard cars, but the master cylinder wiring is usually there. Do note that many other ford vehicles with bendix master cylinders like the taurus, mustang, f150, etc also use a 6G alternator wiring pigtail on their master cylinder too.

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.
