Servicing an EDA4700T means working from LIT-19616-00-12, the Yamaha manual that covers this generator together with the EDA300, EDA300DV, EDA4700(E), EDA4700DV(E), EDA5000(E), EDA5000DV(E) and EDA5000T.
Eight model codes in one volume is unusual but sensible here, since the units share their principal assemblies. The manual keeps them distinguishable in its tables, and the T suffix on your unit is what points you at the right row.
The procedures are the factory's own: removal and installation in order, inspection with the measurements that determine whether a part is serviceable, torque specifications, wiring diagrams for the generating and control circuits, and fault-finding sequences that start from what the machine is doing.
Verify EDA4700T on the data plate before you order or begin.
