Features This is a motor voltage regulator, AVR, rectifier. If your generator doesn't have an output and/or your battery doesn't charge, this is the part that probably needs to be replaced. This voltage regulator is usually mounted on the motor and used to charge the battery. You need to make sure your generator has these same connections. This rectifier is suitable for KDE3500 5000 6500 6700. This regulator has 2 sockets with a total of 3 wires. Description: This is a motor voltage regulator, AVR, rectifier, with 2 sockets with a total of 3 wires, usually mounted on the motor and used to charge the battery. And suitable for KDE3500 5000 6500 6700. Features: Model: 178/186 KDE3500 5000 6500 6700 Applicable area: agriculture Accessory type: motor accessories. Material: Aluminum Colour: as shown in the picture. Voltage: DC12V Size: as shown in the picture Weight: 198 g Package includes: 1 x Voltage Regulator. Special Note: Our 12V voltage regulator has 3 wires: 2 blue or green wires for AC generator voltage input and a red wire for DC voltage output on 12V DC battery. The integrated electrical circuit is grounded internal to the housing of the part itself as the fourth grounding wire. It is equivalent to a 12V 4-wire voltage regulator. Package List
