We use the smallest, lightest Japanese alternator available. This ND unit measures a mere 88mm across which is roughly about the size of a soft ball. Light weight and 40 amps strong at just 800 rpm these "brand new" units offer enough juice to run all your circuits plus a cooling fan and a pair of halogen lamps. The key is it's low rpm output.
Our black anodized mounting hardware is simple and compact allowing air pump retention.
Grade 8 fine thread fasteners, Stainless Steel adjustment bracket and belt included. Connects using existing 3 wires to the original Lucas alternator.
