How long will it take before my order ships-
Orders ship in approximately 15-20 business days, sometimes sooner. If for some reason parts are on back order, we will notify you, but this is not common. If payments are being made on an order, your order will not start processing until after it is paid off.

Slipping belt – Each of our high output alternators come with smaller overdrive pulley. This pulley is made to increase low RPM charging for maximum output. It is custom for the diameter of the overdrive to be less than your factor pulley, depending on the kind of vehicle you own. For this reason, unless otherwise specified, you will need at least a 1/2 inch shorter belt. You can purchase this from any auto parts store. In using the belt and the pulley system, ensure that each part of the pulley system is free of oil or grease, this will help its efficiency.

Regulator plug – It is important to make sure that the small regulator plug that is located on the back of the alternator is well plugged in for the correct functionality. Do not forget to plug it in completely, try not to jam the plugs in backwards, and avoid pinching it in order not to create a short. For more information on regulators and wiring see installation instructions.

Alternator pulley changed by customer- Our high output alternators come with an overdrive pulley. The pulley is designed to improve low RPM charging so that it yields maximally. Do not change this overdrive pulley out with a larger diameter pulley. When alternator pulley diameter is increased, the output amperage decreases. Changing the pulley will void all warranties

The alternator I got is not working –
Our products are custom built to perfection, bench tested, and confirmed to excel in performance specs before they are shipped out to our clients. The top reasons we have observed why our product may be having a problem include: the possibility of it being damaged during shipping or installation, incorrect install, or the having the wrong alternator or amperage for your application. If you certain you have gotten the right alternator for your application and it was not damaged during shipping, you are implored to refer to our manual for correct installation guide, it happens that if the alternator was not well installed, it will not work.

The alternator I got does not “put out.”
As promised to all our customers, our products are fully tested ensuring their outstanding performance before shipping. In our experience through the years, it is in many cases not the alternator itself. You must ensure you consider a few possible concerns in your troubleshooting – please read the instruction manual thoroughly.

Warranty and Shipping
All orders are custom built. Orders ship within 15-20 business days unless parts are on back order, but customers are notified if that’s the case. We offer lifetime warranty on alternator labor and a one year warranty on parts. All orders are heavily wrapped for shipping with several layers of big bubble wrap and two layers of boxes along with a Fragile sticker on the box. If you have to ship your alternator back, please be sure you wrap it the same way to prevent further damage. See more details on our warranty page.

Battery Light Comes On – Alternator Not Charging
The reason could be one of two things:
Either the plug is wired incorrectly or the computer is sensing the higher voltage and causing the battery light to come on even though the alternator is charging properly. Please refer to the instruction manual tab on the website for specific instructions that will help you with wiring. For some older vehicles, the factory style regulator is not available with the hairpin style alternator. This is why your high output alternator will come already “upgraded” with the 15 volt regulator. It will have an oval plug which requires splicing into the factory plug. This is a simple ,fast step and these instructions are detailed for you in the instruction manual.
