Alternator - SDEC D11-102-30A is the engine auxiliary generator: it produces the DC that carries battery and electronics with the set running.
Before replacing, measure charging voltage at the battery posts at medium speed. It should sit between 13.8 and 14.4 V on 12 V. If lower, check belt and wiring before blaming the alternator.

- Check mounting type and pulley diameter; a different pulley changes the drive ratio.
- Confirm whether the regulator is internal or external before ordering the part.
- The reference shown on this listing is D11-102-30A; cross-check it against the one stamped on the removed part.
Frequently asked questions
Can the alternator be repaired?
Yes, in most cases regulator, diode bridge and bearings are replaceable. On critical equipment keep a spare and repair the removed unit.
The battery drains with the set off. Is it the alternator?
No. With the engine off the alternator is not in circuit. That symptom points to parasitic load or leaking diodes, checked by measuring current with everything off.
