240 Amp S Series Alternator for Select 1963-1985 GM Vehicles
• 240A High Output Alternator
• For use with Select 1963-1985 GM Vehicles
• Custom Machined Large Case Alternator
• 8 Press Fit High Amp Diodes
• Twin Internal Cooling Fans
The L series family of alternators has brought large-case alternator performance and durability to vehicles that were originally equipped with small case units. These kits include a custom machined large case alternator utilizing emergency vehicle internals, and come with the necessary adapter brackets and harness for installation. These kits are manufactured for vehicles where there is no other option but to upgrade to a physically larger alternator. They feature massive rectifiers with 8 press fit high amp diodes and large diameter twin internal cooling fans for excellent durability. The L series is specially designed to have a larger diameter, but shorter alternator body to fit into tight spaces.
This unit has a self exciting internal voltage regulator that does not require anything to be plugged into the alternator.
This unit will more than likely not charge below 800 engine RPM on these vehicles.
This vehicle has a narrow drive belt, and may experience belt slip with alternators of this amperage.
