Troubleshooting no spark yz400f

1 post in this topic

Using a multimeter I tested for voltage at the plug boot. It read from 0 and jumped back and forth from 1 to 3. Same result testing the incoming wire on the coil. I need to unplug the harness coming out of the stator but I need to know what wires to test for voltage and what should it be. Also I was told this bike has no regulator/rectifier. Is this true? It's a 1999 yz400f. Thanks for any help in advance.
