BOYER BRANSDEN POWERBOXES

Replace old Lucas regulators, rectifiers and zener diodes

Get rid of zener diodes and rectifiers. This system is more efficient and reliable.

 

(There are cheaper alternaives on the market,but the Boyer Bransden does not leak a small current like many others. It won't drain your battery in 2 weeks.)
