Charging Issue (very perplexing)
Hi- Since I got my 1999 VT750CD2, it's been bulletproof, and I think I may have jinxed myself when singing its praises to friends with more temperamental bikes. I am in Maine and store it in an unheated garage during our long winters. A few weeks ago, I brought it out and started it up, let it get warm, then put it back for another week (until it was riding weather). It started up, a little sluggish, but it was sitting all winter and I did not charge the battery (I know, I know- I got cocky). I get it out on the road and was riding for about 30 minutes when I pulled over to check out the view. When I went to restart, I got nothing but clicks. I manage to bump start it and get it home. I threw it on a charger, put it back on the bike, then started it a few times when I trailered it back to my apartment (I store it at my family's place). I take it out the next day, am riding for about 30 minutes, and it starts dependably a few times, but then nothing but clicks (had to bump start it again).
I charged the battery again and immediately put the voltmeter on various things:
12.71 after charging, but out of the bike
12.48 when idling
14.58 when throttle is goosed
Then, I waited 24 hours and took the measurements again (as of 10 minutes ago):
12.57 when off
12.22 when idling
14ish when goosed
Also, the connection at the rectifier is a little cooked (I attached pics) but it seems like it's still making contact.
So, do you think this is a battery thing, or a regulator/rectifier thing? I am between jobs at the moment, so would like to be as efficient as possible when throwing parts at my bike.
Any input would be greatly appreciated- thanks so much!!
