Hello all
I have a 77 iron head sportster and am having issues putting the regulator back on this bike I recently picked up. I understand that the green wire and tan wire from the generator go to it. I also know that the red wire/ ignition wire, goes on it as well. However I don't know where they are supposed to be screwed onto it at. All I see are numbers and + symbols stamped into the metal on it.

 

We have a Classics Ironhead section, where you may get an answer to your query, I suggest you call in there.
