Basics - 1. First charge up the battery. Then go to Autozone and get it load tested. Sounding like its crap. Before going further and doing the rest of the tests, you need a rock solid battery. 2. You need a voltmeter - Crank it up. Check DC volts at idle,and 5000 rpm, across the battery terminals. Should be 13s at idle and 14s at 5000 rpm 3. Check Stator ------a. pull the connector apart that goes to the R/R, stator side. Usually the wires are yellow. Check resistance pin to pin. A to B, B to C, C to A -- should be less than 1.0 Ohms -------b. Check each pin: A to ground, B to ground, C to ground for continuity. Should be infinity. NO continuity. -------c. Check stator output. AC volts. Start bike. Pin A to B, B to C, C to A. Should 15ish at idle and rise into the 60s plus on each test. If you do these tests, you can get a data point on figuring out what parts are junk. GL
