To ensure correct generator charging of your battery , it is often necessary to adjust or install a new voltage regulator in the system. This article will deal with replacement using a new, working regulator.
1.Disconnect the battery’s negative cable and then the regulator wire marked BAT (battery) from the existing VR (Hint: Use tags or tape to identify for reattachment of all wires) Next, disconnect wire from ARM (armature), and then from FLD (field) . If a wire is connected to the mounting screw for ground, disconnect and tag.If a condenser is present, note its connection.
Remove mounting screws and observe the positioning of the VR. Remount new unit in same location (You will have already acquired the correct 6 or 12 v VR. Reconnect wires in the same sequence as removed.You are NOT done!
POLARIZE THE CHARGING SYSTEM. IT WILL NOT WORK IF YOU DO NOT POLARIZE!
Start by taking a piece of wire (14 gauge or better) around 8″ long. Hold one end against screw head on the BAT terminal. (See drawing) Touch the other end to terminal marked ARM for a maximum of two seconds. DO NOT TOUCH FLD OR ANY OTHER METAL PART. There may be a spark, but it won’t hurt you. You should see the generator move just a bit. Thats it. Done!
You will want to start the vehicle and observe that the ammeter is now charging or your charging light is off.
NOTE: A battery in poor condition or has a low charge can cause the VR to appear defective. Make sure it has a good charge before you assume a faulty regulator.
first time anyone has made it so clear….. thanks.
