Alternator.

Rebuilt this today.
Realised I had no idea which wire went where on the slip rings.
Since they're just connecting an electromagnet I just soldered them back on.
Correct?

Not quite sure what you did. Did you take a photo to show us?

Two wires terminate the rotor field windings to the slip rings. This alternator has the later flat plate slip rings

The field wires have no identification and could be connected to either inner or outer ring.
I don't think it matters. Does it?

I would say electrically no difference

The stationary windings have an alternating EMF and that is then rectified and smoothed.

Thanks Jon The Chief,

Much as I thought but wasn't sure.

But aren't we talking about the connections to the rotor windings here?
