I reved it above 1500 only to keep it from stalling on me before it was warm enough. But I'm doing this solo so I had no way of taking a reading and reving it at the same time. Oh wait, I guess i could have done this using the throttle in the engine right? Duh.....
...So I just made the measurement and revved it up to probably at least 2500 or even 3000 rpm and the voltage never budged. It seemed to slightly climb weather or not the engine was revving or idling. It was showing about 12.5 V.
Then when I shut it off it almost stayed the same but climbed slowly to 12.7V over a period of about 3 or 4 minutes. I Imagine it continued climbing but I havent been out to check again.
