Embedded electrical circuit is internally grounded to the case of part itself as the fourth grounding wire. It is equivalent to a 4-wire 12V voltage regulator._x005F_x000D_Please note that the color of wire will be sent randomly, and make sure you will not mind before ordering. 1This is a engine voltage regulator, AVR, rectifier 2This rectifier is suitable for KDE3500 5000 6500 6700 3This voltage regulator is typically mounted on the engine and used to charge the battery 4This regulator has 2 plugs with a total of 3 wires 5If your generator has no output and/or your battery isn't charging, this is the part that most likely needs replaced
