Alternator - SDEC D11-102-10A is the engine charging alternator: it keeps the battery floated and powers the controller while the set is running.
The charging alternator ages from heat and from brush dust. The sign it is failing is not a red lamp but a battery that drains between tests: the set cranks fine and by the third test will not turn.

- The reference shown on this listing is D11-102-10A; 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.
