Overview
The 26SI is a brush-type alternator in the 12V/75–85A and 24V/50–75A range, designed for medium-duty trucks, farm equipment, and off-highway applications where a dependable, straightforward alternator is required. Sealed heavy-duty bearings handle extreme belt stress, built-in air baffles restrict foreign material ingress, and a diode trio/capacitor assembly provides RFI suppression to protect onboard electronics.
