I tested the output while the engine was off from the battery, it was about 12.5 volts, which sounds good. I hooked the voltage meter to the alternator output and when the engine was reved it showed around 17 volts just like in the cab. The odd thing is that when the engine is idling (around 1000RPM) it shows about 12.5-13 volts. My alternator is internally regulated, unless someone messed up when I ordered it. I ran a heavy 10 guage ground wire from the alternator to the frame without luck. I noticed that when the engine was running, the regulator was making a loud clicking noise, maybe it is bad or needs adjustment. I will see it the DA plug has a broken wire by ohming in out. Unfortunatly the alternator test did involve O'Reillys so I guess it wasn't professional then. As for the battery, I actually replaced it yesterday so I know it is good. I wonder if this high voltage ruined my old one somehow. I live in southeast MO near Poplar Bluff, probably the furtherest away from Kansas that you can be in Missouri.
