Ample Power Alternators
Ample Alternators are high quality, high output, brand new alternators that are designed for continuous output for as long as it takes to charge batteries to the full mark. You can't buy better performance from an alternator at any price ...let us amaze you with more Amps than you thought possible ...at any RPM! Higher Output at Low RPM Given below are alternator outputs versus temperature and alternator RPM. Note: All alternators are P-type units except the 32 Volt, #4132 model.

How good are Ample Alternators?
Compare the output current given above to the outputs
of other
brands at the same alternator RPM and at the same temperature.
You'll discover that Ample Alternators put out more Amps at
every point!
Alternator
RPM is given, not engine RPM. Engine RPM is always less ...
it depends on the pulley ratios. A Yanmar engine
with a 5.4 inch, (132 mm), pulley running at 1200
RPM will spin an alternator with a 2.6 inch, (66 mm),
pulley at 2500 RPM. In the rating charts the cold Amps rating is for an
ambient air temperature of High Voltage Diodes We all know that opening the battery selector switch under load can blow up alternators, regulators, and attached electronics. An optional snubber can be purchased to help prevent such disasters. We use 200 Volt diodes in the alternators to help avoid meltdown if the switch is opened. Other manufacturers use only 100 Volt diodes ... a certain failure if the battery switch is opened while the engine is running.
Alternator Features
Dimensions and Mounting Dimensional Drawings are available from Ample upon request. The #4023 is a standard small frame mount used by Ford and GM, and bolts in place of Delco and Motorola alternators with a 2 inch, (50.8mm) foot. We also provide the #4023 unit with a 1 inch, (25.5mm) foot. The #4023-S is a saddle mount unit that replace Hitachi and Mitsubishi alternators found on Japanese engines. Alternators #4059 and #4060 also have a 2 inch, (50.8mm) mounting foot and will often replace small frame units where there is a couple more inches, (50-75mm) available around the engine. The #4109 unit is a 24 Volt unit with a 3 inch, (76.2mm) mounting foot. The #4110, #4132, and #4300 are the SAE J-180 mount. Standard pulley dimensions are 1/2 inch, (12.7 mm), single belt by 2.6 inch, (66 mm) outside diameter for model #4023. For the #4059, #4060 and #4109, a double 1/2 inch, (12.7 mm), belt by 3 inch, (76.2 mm), outside diameter pulley is standard. Two belts are recommended, but the #4059 will operate on a single belt if the belt is tensioned frequently. Belt Requirements All alternators require heavy duty belts, such as the Super HC Series from Gates Rubber Company. Their industrial CV series belt is even better but hard to find. Another favorite is the Dayco Top-Cog. While belts need to be tensioned properly, a belt that is too tight will cause the rear bearing in the alternator to fail prematurely. Check with your belt manufacturer for belt tension guidelines. Fan Rotation Alternator fans are designed to suck air through the alternator from the back to the front. Most engines rotate clockwise when facing the front of the engine, and fans are optimized for CW rotation. If you have an engine that rotates counter clockwise, specify a bi-directional fan to assure proper cooling. Isolated Grounds The large frame alternators come standard with isolated grounds. Isolated grounds may be ordered on the small frame, #4000 series by adding an I to the part number. For instance, the #4023I-S is the saddle mount unit with isolated ground. Ordering information

Accept Only Ample Power Don't let someone give you a ``substitute'' and call it equivalent. Insist on 100% Ample Power! Offshore Rebuild Kits While you may never need a rebuild kit, a long distance cruiser should be prepared for any eventuality. Below are rebuild kits for the various alternators. Included in the kits for the #4023, #4023-S, #4024, and #4024-S are: front and rear bearings, brush assembly, diode/heatsink assembly, and stator. Included in the kits for the #4059, #4060, and #4109 are; front and rear bearings, brush assembly, 3 negative diode assembly, 3 positive diode assembly, and stator.

Smart Regulation All Ample Power regulators use microcomputers to achieve performance not possible any other way. While multi-step performance can be achieved without a microcomputer, the addition of the computer enables more features. For instance an Ample regulator will go back into absorption mode if the alternator can't keep up with demand. System troubleshooting is also made easy with the diagnostic capability of the microcomputer and its error reporting via flash codes from an LED. See the regulator data sheets for more information. Battery Temperature Compensation The faster a battery is charged, the more important temperature compensation becomes. Ample Power regulators have had battery temperature compensation since 1987. System Integration
While Ample Power regulators operate effectively in
a stand-alone mode, they can also be interfaced to the
EMON II. When interfaced to a monitor, charge perfection
is achieved since the monitor knows battery voltage, current, temperature
and state-of-charge.
