Eliminate charging issues and modernize your air-cooled electrical system with the EMPI 90+ Amp Alternator Kit. Engineered for high-demand vehicles, this all-new alternator features a high-tech armature and an integrated internal voltage regulator, providing unmatched reliability for cars running modern EFI, high-output stereos, or advanced lighting.

Finished in a durable satin black, this kit doesn't just perform—it serves as the centerpiece of a clean, coordinated engine bay. Despite its massive 90+ amp output, this unit is designed to run cooler than traditional dual-fan models while actually drawing less horsepower from your engine to operate. It is the definitive charging solution for the performance-minded builder.

Key Features:

• 90+ Amp Output: Provides maximum charging power for modern accessories and stable voltage across the entire RPM range.

• Internal Regulator: Simplifies your wiring by eliminating the need for an external mechanical regulator.

• High-Efficiency Design: New armature technology allows the unit to run cooler and more efficiently than standard 55-amp or dual-fan alternators.

• Complete Conversion Kit: Includes the alternator, stand, pulley, 3-piece backing plate set, strap, and belt.

• Black Finish: Perfect for "nothing to hide" builds, matching black tins, or custom "blacked-out" engine themes.

Installation Guide: Step-by-Step

Note: This kit requires a high-amperage ground path. You must run a minimum 10-gauge ground wire from the alternator body to the engine case studs.

1. Safety First: Disconnect the negative battery terminal.

2. Remove Old Unit: Remove your existing generator or alternator, along with the stand and backing plates.

3. Install the Stand: Mount the new alternator stand to the engine block. Ensure the surface is clean for a proper seal.

4. Wiring Preparation: If converting from a generator, bypass the external regulator. Connect your main B+ (battery) wire to the post on the new alternator.

5. Grounding (Critical): Install a 10-gauge ground wire from one of the alternator's body bolts directly to the alternator stand studs on the engine case. This ensures the high-output amperage has a clear path and prevents damage to the internal regulator.

6. Assembly: Install the 3-piece backing plate set onto the alternator. Mount the alternator to the stand and secure it with the included strap.

7. Pulley & Belt: Install the alternator pulley and belt. Adjust shims as necessary to ensure proper belt tension and pulley alignment.

8. Final Check: Reconnect the battery. Start the engine and verify that you are seeing 13.5V to 14.5V at the battery terminals.
