The alternator I bought from you doesn't work.

Each alternator is bench-tested before shipping. Apparent failure is usually due to ordering the wrong unit, shipping damage, or installation mistakes. Verify the part number, inspect for damage, and review the proper installation steps (Technical Tip TT-648) before contacting support.

The alternator I bought from you doesn't "put out".

Low-output symptoms are often caused by factors outside the alternator. Measure voltage directly at the rear of the unit with a digital meter; if readings seem low, check the common issues listed below or return the alternator for a free bench test.

High-output alternators ship with an overdrive pulley that may require a belt about 1 inch shorter than stock. Use a quality, oil-free belt to prevent slip and ensure full output.

Regulator plug not plugged in, not seated properly or pinched wire

Make sure the small regulator plug on the alternator is fully seated and oriented correctly. A pinched or missing connection will prevent charging. Self-exciting models (e.g., Fitzall 220A+) do not use this plug.

Battery warning light bulb in dash missing, blown or bad connection

Some vehicles rely on the dash battery-warning bulb to excite the alternator. A blown, missing, or poorly connected bulb can cause a no-charge condition.

Customer changed alternator pulley

Replacing the supplied overdrive pulley with a larger-diameter pulley slows the alternator and decreases charge output.

Vehicle crankshaft pulley diameter too small

Aftermarket under-drive crank pulleys spin accessories more slowly and can severely reduce alternator output. Ensure the crank pulley is at least OEM size.

Main vehicle charge wire too small or not upgraded

Factory charge wiring is sized for OE amperage. When loads rise, upgrade to a heavier-gauge cable such as the Big Zero kit to avoid voltage drop and false low-output symptoms.

Too many grounds, insufficient grounds, or just bad wiring

Improper, corroded, or excessive grounds-as well as undersized or poorly crimped wires-can cripple alternator performance. Have a qualified technician inspect and correct wiring.

Bad, old, weak, damaged or cheap battery

Weak or inexpensive batteries-especially some gel-cell types-may not accept the alternator's current. Use a healthy wet-cell battery with sufficient cold-cranking amps.

Alternator possibly damaged during installation

High-output units contain sensitive electronics. Skipping the recommended battery-disconnect procedure or other steps in Technical Tip TT-648 can damage the regulator and cause no-charge conditions.

The alternator I bought from you doesn't fit.

Direct-fit models require no hardware changes. Universal Fitzall 220A+ units need custom brackets and may require a shorter belt.

Do you sell brackets, spacers or hardware to mount the Fitzall on my particular application?

Due to the vast number of vehicles, PowerBastards does not supply custom mounting hardware. Most customers fabricate brackets themselves or hire a qualified shop.

I tested my alternator and it only makes 30A.

Alternators supply only the amperage the system demands. Clip-on amp meters can be inaccurate; 30 amps may be normal at low load. Send the unit in for a free certified output test if in doubt.

PowerBastards Product FAQ

Will this fit my Buick Riviera ?

Yes! Our 220A High Output alternator for the Buick Riviera is built as a direct-fit replacement. It is designed to use the factory mounting points and original style electrical connections unless noted otherwise.

Will your 220A high output alternator damage the computer in my Buick Riviera ?

Our high output alternators are designed to work seamlessly with your vehicle’s electrical system. Our alternators are fully compatible with your Buick Riviera. They meet and exceed OEM performance specifications. In fact, you can install our high output alternator in a completely factory Buick Riviera and your new alternator will operate exactly as designed.

Do I need a shorter belt ?

Your factory belt should work just fine with the new alternator, if it’s in good condition and was the correct length to begin with.

If you have any questions during the install, feel free to reach out.

Do I need the BIG ZERO Wire Kit ?

For high output alternators, upgraded charge wiring is strongly recommended. The BIG ZERO kit is designed to safely carry the additional amperage from the alternator to the battery without adding unnecessary extra grounds that can interfere with modern vehicle charging systems.

Do you have a higher amp model ?

Our 220A High Output alternator is the highest reliable amperage available for this Buick Riviera. Pushing the alternator beyond its reliable operating limits can compromise performance, increase noise, and reduce long-term durability. Our high output alternators are engineered and calibrated to deliver maximum usable output across the entire engine RPM range while maintaining reliable, quiet operation for years to come.

Will too many amps damage my car ?

No. By design, your vehicle only uses the amperage it needs. A higher output alternator provides additional charging capacity when demanded by added accessories and electrical loads.
