Nope. Lots of us just leave the kill switch in RUN position and forget about it.nickleo373 wrote: ...just remembered the two times the battery died I left the kill switch on the run setting. Does the bike draw power if the kill switch is on but the key is off?

Not supposed to. Go back and do the test again, be sure the meter is set to 10 DC Amp's. You may well have to move the red lead to a different socket in your meter.nickleo373 wrote: I gave into my curiosity and checked with the AMPS setting It's reading 0.0 so I'm assuming there's no draw.

With the meter at the battery cable, turn the Start/ Stop switch ON. If the bike is wired correctly, it should still read 0. Only when you turn the ignition Switch ON should the Start/ Run switch have power through it.
Did you do the AC Volt test, black wire on Battery negative, Red lead at R/R Red wire Bullet connector before the battery Positive? With it running of course. So if you can measure any AC Vots. If it measures less than 1/2 a volt, .5 ACV, that's fine. But if you get much more like a volt or more. Then your Rectifier has a leaking diode. Then I would replace the R/R assy.

One:
If you are only running the bike while doing tests, and not actually riding it any real distance, the battery may be draining, but not getting enough time to recharge. It takes a good 10 minutes of sustained riding to fully recharge from a cold start.
The 550's, when working properly, will get to about 14.2 to 14.6 max, when revving. If it shows higher, it's usually due to voltage losses in the sensing circuit (brown wire to the reg/rec).
Two:
If you are riding it for a decent amount of time, it could be the regulator is failing. The most common way for these reg/recs to fail from old age, that I've seen, is they lose voltage over the course of a ride. At first they appear fine under brief tests. Revving will show 14v+. But on a long ride, the 14v will gradually reduce to under 12v. It's difficult to diagrnose because you have to ride it for over a half hour with a voltmeter attached and watch the voltage.
