 Standard Internal Regulator Alternator

The 12-SI Alternator has the same outside dimensions as the10-SI (shown below) and will fit in it's place without modification.
The 12-SI has several design improvements over the 10-SI that make it the better choice between the two.

Improvements include:
· Larger Rectifier to handle more Amps.
· Wider Stator and Rotor for improved
Magnetism for Better Low End Output
Plus the increase in mass helps with Heat Dissipation
· Larger Cooling Holes at back for Better Cooling of
Rectifier, Stator and other internal components
