Agree with CSC that the kawi should have a 3 phase system.... -- To add more fodder to the mix..... --Your gonna have to do a serious dig into your charging system......-- Check to see that your connectors are good, I've seen some nasty burn up parts, especially the stator connector. ---If they are toast - fix first. -- Your are going to need a reasonable quality digital multimeter. Lots of places have them. Then --- ---Go through this starting point quick list. Steps: - Recharge battery overnite - then to take it to Autozone or similar to load test. -- Good? Bad? – An iffy battery can fake you out and act like a bad R/R. Buy new if needed. - With good battery fire it up, warm up for a minute or two. These are R/R quick checks--- --- With voltmeter at battery get voltages -- idle volts? 5000 rpm volts? What’s the numbers? Should be in 13ish idle and in 14s at revs. - Check stator - 1. Pull connector apart. Set meter to resistance. Check pin to pin, 3 yellow wires, A to B, B to C, C to A. What’s the numbers? 3 separate readings --Should be less than 1.0 ohms. - 2. Check continuity from each A,B,C pin to ground, -- -should be infinity - nada nothing. no continuity. -- 3 separate checks . - 3. Crank it back up. Do another pin to pin thing, but set meter on AC volts. idle and 5000 rpms. What's da numbers? Should start 15 -20ish and climb 50ish and more. Again – 3 readings - Repeat hot. This quick list will catch the obvious stuff, but if you need to dig deeper check this chart. http://www.electrosport.com/media/pdf/fault-finding-diagram.pdf Knock out the numbers, write 'em down and tell us what they are. -- We'll go from there. ......
