Hey folks, Been cruising the forum for sometime but this is my first post. Y'all have been a wealth of information and frankly a pleasure to read about. Thanks for that! Now, onto the bike. It's an 82 haritage special, stock apart from the bars, the jerker exhaust system, and my upgrading the brakes. It's got about 24,500 miles, and has been running great, albeit a little hot, whenever the charging system doesn't throw a monkey wrench into the works. Latest issue is: first I got a new rotor from mikes, the cheep piece of shit not only needed the rare earth magnet mod but after less than 50 miles the screws backed out, causing the glue over the soldered connections and the connections themselves to brake. Suffice to say it wasn't working until I learned from you guys to check for that and was able to solder it back up and throw some locktite on the screws. Everything was good when I first got the rotor, now that it's back running suddenly I'm overcharging my battery. I've gone through curlys guide a lot and everything seems to check out, with the acception that the ac voltage between the white wires at the stator plug is reading 9VAC rather that 10.5-11VAC. All subsequent tests in that section check out correctly though, so I'm not sure what to do with that information. Personally when I see the voltage rise past 14.5VDC when I rev the engine I expect the regulator to be the issue. However, according to the curlys guide, if the slap test checks out then your regulator is fine. Can someone explain that? I'm not sure how checking that the alternator is creating its magnetic field correctly says anything about the function of the regulator. Anybody got any thoughts?
