178F/186F VOLTAGE REGULATOR AVR DC12V FOR KDE3500 5000 6500 6700 Features: This is the motor voltage regulator, AVR, rectifier. This rectifier is suitable for KDE3500 5000 6500 6700. This voltage regulator is usually mounted on the motor and is used to charge the battery. This regulator has 2 plugs with a total of 3 wires. If the generator has no output and/or the battery is not charging, this is the part that most likely needs replacing. You need to make sure your generator has the same connections. Technical data: Model: 178/186 KDE3500 5000 6500 6700 Applicable area: agriculture Accessory Type: akcesoria Engine Material: Aluminum Voltage: DC12V Weight: 198g Package includes: 1 x Voltage Regulator Special note: Our 12V voltage regulator has 3 wires: 2 blue or green wires for AC voltage input from the generator and one red wire for DC voltage output to 12V DC battery. The built-in electrical circuit is internally grounded into the housing of the part itself as the fourth ground wire. This is equivalent to a 4-wire 12V voltage regulator.
