A day or so ago, I pulled into a parking spot, and before I could turn
of the engine, the battery light and the O2 sensor light came on. That
was odd I thought. I took care of business, and when I started the
engine again to go home, the battery light and the O2 light did not go
off. I checked the belts and the battery (what for I don't really know -
had it been down the thing wouldn't have started). After farbling around
a bit, I rev'ed the engine to 2000 rpm and the lights went out. Below
that and the lights came back on. This pattern has remained, but it has
gotten worse. I have to rev the engine even more now before the lights
go out, and they don't stay out. Engine rpm must remain quite high for
the lights to remain out.

I'm guessing that the regulator part of the Alternator is failing. Has
anyone got any ideas?

Thanks,
