Mark Grasser DC Power Solutions - Stage Two Large Frame Alternator with J-180 Saddle Mount
The Mark Grasser DC Power Solution "Stage Two Large Frame Alternator" with J-180 Saddle Mount is a 200A behemoth and can deliver as much as 140A at idle. This large frame alternator is virtually Indestructible. These alternators are specifically designed to spin at low RPM and not suffer from over heating. The same speeds found on trawlers or sailboats while charging on the hook. These alternators are ideal for high demand, long bulk duration charging in both boats and RV's. Pair this alternator with a Balmar MC-614 and you've got a very nice charging system.
This alternator is manufactured using stainless steel assembly and mounting hardware. Surfaces are machined flat for ground connections and temp sensors. This makes for better electrical connection and better thermal conduction. The Stage Two 200A also features a back up 14.5 volt Internal regulator. All alternators are ready for an for external regulator connection. The Stage Two is supplied with a "2V" pulley for two 1/2 inch belts. If ordered with a a Mark Grasser serpentine pulley kit it will be supplied with the serpentine pulley. Any other pulley would be a quote request. A connection for an indicator light is provided as is a tachometer/stator output. All Mark Grasser DC Power Solution alternators are assembled and tested in Kenosha, Wisconsin USA.
