This kit is designed specifically for the B,IB,C and CA Tractors upgrading to a Voltage Regulator instead of using the 3 position light switch. This is a nice upgrade for the 6V system. The voltage regulator mounts on the Generator right where the cutout relay was sitting. VR wiring included with this kit. 
 
B&B Tech Tip: We also offer a toolbox mounted VR kit to hide the Voltage Regulator should you want to hide it or keep it out of the elements. We can build your new wiring system kit for the in toolbox VR option . Email or Call us for this option.
