As I'm getting ready to reassemble the K301 (questions on THAT to follow!) I have a question about the regulator. The 140 was not charging at the time that I removed the engine. Some time in it's history there was much 're'wiring done. The amp gage wasn't connected, a ground pigtail was left on the sheet metal, etc. I finessed the harness according to the schematic and hope it'll be fine. What I'd like to know is what should I expect from the center pin on the regulator? (Assuming the engine will work!) How many volts should come from that?
