I'm sure this has been asked one thousand times, but a lot of information I've found online always seems to contain a lot of guff that confuses things. I just wanted to confirm and he sure.

I've converted my 1965 side points C15 to 12 volts and swapped the original rectifier to a Podtronics type of reg/rec.

Looking at the wiring, I know that two of the three wires for the alternator are joined to one of the yellow wires on the reg/rec. The remaining wire from the alternator is joined to the other yellow wire of the reg/rec. The red goes to earth.

Where does the black from the reg/rec end up? Does this run to the ammeter?

Many thanks in advance.

Hi Courtney,

Alternator Green/Black and Green/Yellow wires.

Alternator White/Green wire.

The Red goes to the battery positive terminal. thumbsup

Standard "positive earth" mean metal bits of the bike are connected to the battery positive terminal. So there is nothing gained (but much potentially to be lost) by connecting the reg./rec. Red to a random bit of bike and then expecting another electrical connection possibly as old as the bike to complete the circuit. thumbsdown

If your bike has an Ammeter, connect the reg./rec. Black wire where the rectifier DC output was connected - Brown/White wire?

Hth.

That's great, thank you! I appreciate the straightforward answer.
