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.

The BIG ZERO Wire Kit Explained and Why You Need It

Date Added

3/3/2025

A powerful alternator is only as good as the wiring that connects it to your battery and electrical system. If you’re running high-powered accessories, upgrading your wiring is just as crucial as upgrading your alternator. That’s where the BIG ZERO Wire Kit from PowerBastards.com comes in.

What is the BIG ZERO Wire Kit?

The BIG ZERO Wire Kit is a premium high-amperage wiring upgrade designed to reduce electrical resistance, improve charging efficiency, and maximize power delivery to your vehicle’s electrical system. This kit ensures your alternator operates at full capacity without bottlenecks caused by inadequate stock wiring.

Why Upgrade Your Wiring?

Factory wiring is often undersized for high-performance applications, leading to voltage drops and inefficiencies. Upgrading to the BIG ZERO Wire Kit offers multiple benefits:

Maximized Power Flow – Allows your high-output alternator to deliver full amperage without restriction.
Reduced Voltage Drop – Ensures stable voltage levels for better accessory performance.
Improved Battery Charging – Keeps your battery fully charged, even under heavy loads.
Increased System Efficiency – Prevents overheating and electrical bottlenecks.

Why the BIG 3 Wire Kit is Outdated

Many automotive enthusiasts have heard of the "Big 3" upgrade, but this older method is no longer the best solution for modern vehicles. The BIG 3 wire kit is outdated, unnecessary for most cars and trucks, and can actually introduce more problems than it solves. Adding too many wires can cause ground loops, leading to electrical noise in your speakers, system instability, and complicated troubleshooting. Instead of cluttering your engine bay with excess wiring, the BIG ZERO Wire Kit provides a streamlined, efficient solution that improves performance without unnecessary complexity.

Additionally, most modern vehicles use a chassis ground system, meaning the entire vehicle is already entirely grounded. Unless the original grounds are missing or damaged, adding extra grounding wires with the Big 3 upgrade is redundant and unnecessary.

What’s Included in the BIG ZERO Kit?

The BIG ZERO Wire Kit from PowerBastards.com includes premium 0-gauge oxygen-free copper (OFC) cables for superior conductivity and durability. The kit comes with:

Heavy-duty 0AWG alternator to battery positive cable
350A Weather Resist ANL Style Fuse
High-quality connectors and heat shrink for a secure installation
Posi-Boot for insulated and safe connections to alternator

Installation and Performance Gains

Installing the BIG ZERO Wire Kit is a straightforward process that delivers immediate improvements. You’ll notice brighter headlights, better audio performance, and improved battery longevity. Some customers are even reporting their windows roll up faster! Plus, the robust 0-gauge cables ensure your system is future-proofed for any additional electrical upgrades.

Power Up with the BIG ZERO Wire Kit

Don’t let weak factory wiring limit your build. Upgrade today with the BIG ZERO Wire Kit from PowerBastards.com and experience the full potential of your high-output alternator!
