Battery not charging
So I drained the battery on my bike last week, tried jumpstarting it, but the battery wouldn't hold any charge so it wouldn't stay running. I replaced the battery, and now it'll run for hours once started, but I can only start it ~5 times before the battery dies. I had tested the charging system across the battery when I first put it in fully charged and it was showing 13.8V at 4k RPM so I thought it was good, but today I don't see any change from battery voltage to charging voltage at any RPM.
I tried testing resistance from the stator leads to ground and all of those were open (good sign I think), so I tested resistance on the regulator leads. I got readings of several mega ohms for A1,2,3 to ground and from battery to A1,2,3 and if I'm reading this right that means that the regulator is shot?
To test the voltage on the stator, I'm I reading it correct that I am to disconnect the bullet connectors from the stator (so that the connections are open) and run the bike off of just battery power while testing the voltage on the stator leads? Also, instead of running it off battery, would it be alright to run it off of a 12V power supply (the battery charger I have can supply enough power to turn the starter)?
Edit: I also tested the resistance between the stator leads, every combo came up to ~1 ohm, which according to a diagram I found seems high. I also tested each combo on the r/r, everything was either open or in the mega ohm region except for ground to monitor which came up at 30k ohm. I got the battery charging tonight and hope to fire it up tomorrow morning to test the voltage from the stator. Here's to hoping it's good and my only problem is the regulator.
