C-165 not charging

What is the procedure to troubleshoot?  Does the voltage normally go bad? Wiring looks good.

First thing to do is clean and tighten ALL electrical connections including grounds. Test the voltage regulator by using a multimeter set on DC 20 volt setting and you should have 12+ volts on the "B+" terminal of the regulator with the engine not running but the key switch ON.

     If you don't have 12+ volts then go to the R terminal of the ignition switch to see if you have voltage there.

     If there is voltage at the voltage regulator "B+" terminal then start the engine and see if there has been any change in the voltage.

Next place to check would be the two AC terminals on the voltage regulator. With the engine running at about half throttle and your multimeter on the AC Volts scale you should read about 35 AC voltage between the two AC terminals.
