My 2002 Honda CRV with 87,000 miles just recently had the
airconditioning compressor replaced along with the filter and
expansion valve by my local mechanic. Since then I noticed that the
green square around the shifter indicator and the cruise control light
slightly flicker when the car seems to be under load. This happens
with the AC on or off. When I slow down to an idle, the light seems to
stop flickering. The flickering is a slight change in brightness in a
constant cyclical nature seeming as if the voltage regulator is unsure
whether to charge or not. No other lights seem to show this. I looked
at the dome light and it seems stable. The radio dial seems stable.
The odometer seems stable. I do not get any battery indicator on the
dash or any check engine light illumination.

I am somewhat baffled as to where to look to begin to track this down.
I don't want to be a parts changer but rather would like some
suggestions as to where to look. I have the full tech manual for this
car but did not find anything in the trouble shooting that references
this kind of problem.

Any advice will be very appreciated.
