This replacement diode board works with ALL 1970-'95 BMW twins.
The charging systems in Airhead models have often been criticized for their shortcomings, and the diode board usually gets singled out as the weakest part of the system. Thunderchild has designed an improved diode board that makes life easier for Airhead enthusiasts.
Very rugged, much less prone to overheating, built with high grade components for reliability, easy to install, and costing almost FIFTY BUCKS LESS than the stock unit, choosing the Thunderchild replacement diode board is a no-brainer.
Includes everything you need and complete instructions for installation.
