12v from 3 brush Ford generator

[Pdgx]

Is anyone using a Ford 3 brush generator on a 12v system ?

With the Fun Projects conversion regulators unavailable, how did you do it ?
What regulator are you using ?

There is no starter involved, and a standalone magneto, so the usage will be minor. Only need it for 12v conversion lights in former carbide lights.

Changing to a different generator is not really feasible as it is used on a ‘22 Mack with a special gear driven mount.
