Tomboy (Tom Gunby) sent me this link to a guy making a regulator: 1968 FORD FAIRLANE INSTRUMENT CLUSTER VOLTAGE REGULATOR - YouTube Is that what you are thinking it'll look like?

Kinda fun to watch him mess up his heat shrink tubing. Why, oh why would he put it on first when the other end of the wire is open? And why try to shove it over a recently-soldered joint? And, he touches his soldering pen to the tubing to shrink it? Gross!

But, the more important question is why use an 8 volt regulator?
