178F/186F 12V DC Voltage Regulator AVR For KDE3500 5000 6500 6700 Generator Descriptions: This is a engine voltage regulator, AVR, rectifier, has 2 plugs with a total of 3 wires, is typically mounted on the engine and used to charge the battery. And suitable for KDE3500 5000 6500 6700. Features: This is a engine voltage regulator, AVR, rectifier. This rectifier is suitable for KDE3500 5000 6500 6700.This voltage regulator is typically mounted on the engine and used to charge the battery. This regulator has 2 plugs with a total of 3 wires. If your generator has no output and/or your battery isn't charging, this is the part that most likely needs replaced. You must make sure that your generator has these same connections. Specifications: Model: 178/186 KDE3500 5000 6500 6700 Applicable area: agriculture Accessories type: engine accessories Material: aluminum Color: as the picture Voltage: DC12V Size: as the picture Weight:198g Package Included: 1 x Voltage Regulator Special Note: Our 12V voltage regulator has 3 wires: 2 blue or green wires for AC voltage input from generator and one red wire for DC voltage output to 12V DC battery. 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. Please note that the color of wire will be sent randomly, and make sure you will not mind before ordering.
