How To Install a Single-Wire Alternator
Add Reliability And Performance To Your Mustang's Charging System With A Mr. AMP Alternator From Performance Distributors
A lot has changed since '65-'73 Mustangs first rolled off the Ford assembly lines. Back then, there wasn't much to worry about regarding power accessories-a radio, a heater blower, conventional headlamps, and maybe optional air conditioning-so Mustangs were fitted with 38-, 45-, 55-, and 65-amp alternators with external regulators. At the time, they could keep up with the demand.
Today, those low-amp Autolite and Motorcraft alternators struggle with modern high-amp sound systems, driving lamps, aftermarket air conditioning, electric cooling fans, and six-way power ashtrays, among other things. When they get hot, diodes pop, regulators clunk, and lights go out. That's why you need to consider the easy installation of a Mr. AMP single-wire alternator from Performance Distributors.
The 130-amp Mr. AMP single-wire alternator keeps a battery charged under all kinds of driving conditions. At idle, count on 65 amps of battery power, meaning lights stay bright and sound systems keep kicking. You can also forget about your Mustang's external voltage regulator, because this alternator is internally regulated with solid-state reliability. If you need greater charging capacity, Performance Distributors offers a Mr. AMP with 190 amps.
The 130-amp version retails for $245.65 in a V-belt design. A version setup for a serpentine belt fetches $220.15.
If you're seeking a more original appearance, Performance Distributors offers the Ford One-Wire Street Alternator. It makes 60 amps and uses its own solid-state voltage regulator. This Autolite/Motorcraft alternator offers reliability while keeping an original demeanor. A deep-groove pulley improves belt traction and alternator speed. The cost ranges from $135.15 for the 60-amp to $301.75 for a 140-amp.
