Greetings! I'm trying to diagnose my charging system on a 99 RSV. I check the battery off the bike, and it reads 12.9V. I connect it to the bike with ignition of, it reads 12.9V. I turn on the ignition switch without starting the engine, it reads 12.3-12.4V. When I start the engine, it holds at 12.3V. When I take her to 5KRPM it hold at 12.3V which according to the ever knowledgeable service manual (I've learned my lesson about not reading the manual when troubleshooting...) is bad. It's supposed to be at or around 14V at that RPM range. So... I now know from that series of tests that my charging system isn't working. I've tested the resistance on my pickup coil, which reads .4 Ohm on both negative leads. The service manual says that it should be between .279 and .34. My Ohm meter is not that sensitive, and doesn't show me 1000ths; it only goes to 10ths. Is .4 significantly out of spec with the .274 to .34 range? I haven't tested the stator yet because I'm waiting for the gasket to come in so I can put it back together again the same day I take it apart. But given the cost of a new pickup coil (I'm looking at about $120USD from my local parts store) I'd hate to replace it only to find out that .06 Ohms is a nominal delta. Thanks!
