Triumph Norton BSA Boyer Power BOX Regulator Rectifier Battery Eliminator PN# TBS-3572A P/BOX00108

The cream of the crop for solid state regulators to suit vintage British motorcycles!

We’ve had countless inquiries regarding running Triumph, Norton and BSA motorcycles battery-less with an electronic ignition…here’s the solution! This Boyer powerbox eliminates your stock rectifier and Zener diode, providing bulletproof solid state reliability in a compact, easy to install package (with installation instructions). Compatible with 12v single phase charging systems, can be used with or without a battery.*

*Caveat; your charging system needs to be in top notch condition to run battery less with an electronic ignition! If your alternator and rotor are still the originally fitted equipment or even older units, the output may not be sufficient to allow your bike to run properly.
