SDEC Alternator

Alternator and charging system parts for SDEC-powered gensets and construction machines. Four things identify an alternator and the engine series is only a starting point: system voltage (24 V across most of this range, though 12 V appears on smaller industrial builds), rated output in amps, the mounting foot and bracket pattern, and the pulley. Single-groove, multi-groove and poly-V drives all turn up on the same engine family depending on what else the machine has to drive. Counting the pulley grooves and photographing the mounting feet identifies the unit faster than any model number. Worth ruling out first: a charging complaint is as often a slipping belt, a corroded earth strap or a failed regulator as it is a scrap alternator.
