Battery charging question- looking at you Gus
Long story short, I've been having an issue for the past month with a brand new battery draining within 2-3hrs of riding. Come to find out, the Stator and regulator/rectifier connectors were charred. I ended up replacing the stator(new), r/r(used), and rebuilt both connectors(new). Since the battery was in warranty, I replaced that as well just for grins. Afterwards I clipped a meter to the freshly charged battery and attached to my tankbag so I can monitor the voltage.
At 5k, the voltage averaged 14.1, cool. Kawi says it should be 14.5v +/- .5 I thought I nailed it, but about 10 minutes into the ride, the voltage at 5k dropped to and stayed at 12.4v(obviously not charging), fuuuccckk.
So this morning I double checked my connections and found a male spade on the stator connector pushed out(cheapo connector). To remedy, I cut the connector off and simply cut off the connector and soldered the stator directly to the harness. I just went for another ride, again with the meter attached. This time, much better. Voltage at 5k were a steady 14.7 for a good 2hrs. Then, all of a sudden nothing above 13.6-13.8. ????
Obviously fixing the connector did something. Before I start chasing ghosts, does anyone know if the 14.5v is a constant, or does the r/r regulate the output according to the charged state of the battery? Also, bearing in mind it was 92 today, does the ambient temp effect the output voltage? Also, before I left the battery was at 12.6v. When I got back a little over 2hrs later, the battery was still at 12.6. Any thoughts? I really dont want to be stranded again, so until I'm 100% convinced its ok, it out of commission.
