Now you can have an 8 Volt charging system to upgrade your factory 6 Volt system. This will provide you with better starts, brighter lights, and better ignition performance. Use our alternator in conjunction with Interstate's 8 Volt battery (part # 1-8V-VHD) and your all done. No need to replace any other components.
Our 8V alternator will produce up to 70 amp and will keep charging even at idle. Also see our conversion brackets to upgrade from an original generator.
This is a 1 wire setup so there is no need to worry about wiring a regulator. Just one cable from the alternator's output post to the vehicle's battery and you are finished.
THIS LISTING IS FOR A NEGATIVE GROUND ALTERNATOR (SEE OUR eCRATER STORE FOR A POSITIVE GROUND VERSION)
Also check out our generator to alternator conversion bracket and our wide groove pulleys in our eCRATER Store.
This alternator comes supplied with a 2 1/4" diameter pulley for use with 3/8" wide belts. We have many other options available. Please let us know the width of your belt (at its widest point) in the comments section during checkout so that we can provide this for you. If you have a question give us a call at (909) 794-1600.
