Part of the Yanmar Operator Manuals.
A YDG that cranks clean but gives you nothing at the receptacles can eat a whole afternoon while the loads it should be carrying sit dead. The troubleshooting chart and electrical wiring diagram in this manual let you work through that fault in order instead of guessing, and the maintenance schedule keeps you from landing there in the first place.
Yanmar published it as operation manual 0AYDG0-G0000 for the YDG2700EV-6EH, YDG3700EV-6EI, and YDG5500EV-6EI diesel powered generators, built on the L48V6-GY, L70V6-GY, and L100V6-GY engines (2005 to 2007). Its 146 pages cover battery activation, diesel fuel and oil specifications, starting and shutdown, AC and DC application, periodic maintenance with a standard torque chart, long term storage, and principal specifications for all three models.
The PDF is bookmarked with 152 entries and prints cleanly, so it lives on your phone or in the binder next to the generator, wherever that happens to be.
