Thanks for the additional explanation Mark. I did tighten the belts a
couple of weeks ago. They had been a bit too loose, making squeals at
startup, and the battery wasn't being charged properly. I haven't driven
much since then (meaning I haven't paid attention to the led's for some
reason). But, I have had no charging problems sinc tightening the blets
nor has the squealing returned. I have driven enough such that if I had
had a charging problem starting at that time, I would have noticed by now.
I'm aware of problems stemming from over tightening the belts, and I'm
wondering if this may have caused anything. I don't that that I over
tightened though. If the rain stops for a little while tomorrow, I'll go
have a look under the hood. (to make one correction, I replaced the belts
rather than tightening the old ones)
Thanks,
David
