We have made 5 of these engine mounted alternators for the Brescia that run twin magneto set up and they work very well. I have a second batch of 5 arriving in December 2020 . Driven from the cross shaft of the engine on the other side of the shaft that drives the water pump, these light and modern electronic alternators are cased in a simple Ali body that drops into the pre machined space.
We can supply a period style brass and steel strap or a cheaper modern stainless band to retain the body.
With only a supply and a charge light to be fitted, this is a simple solution to returning voltage to the battery with all the night driving you can throw at it.
Picture to follow with new batch due Jan 2021.
