Borderline red

[spareparts]

Small silver box is rectifier used on low Amp charging systems, large box with multiple wires is a regulator used with the bigger charging systems. Of you wanted to up grade from the smaller system, it takes a different flywheel, stator, and regulator along with the wiring

Why can’t I find that rectifier ? All the ones I see has a bunch of wires coming out. And does that rectifier adjust the charging out put? What I think I need is a voltage regulator.

No one knows what that silver box is?

Spare said it is a rectifier

[steplift20]

I heard what spare said but all the rectifiers I see have a bunch of wirescoming out of it,what I have ( look at picture) only has two wires going to it held in place with nuts.
