This Intermittent Clock solution might help someone.
Minor detail but it bugged me not to have everything working. My
clock worked fine for a year after I got the car. It is the clock built
into the console in my 81. It got so it changed time on me a lot. I
have worked with electronics most of my life, so I tried to psych it
out. After trying various things suggested, such as replacing
various diodes here and there.
I then I tried connecting it to the Cig Lighter and that didn't
work. Then I finally decided to run a hot wire direct to the
battery. Still no good. I was at my wits end.
I thought, after a year of owning the car, that it did not seem to turn
over very fast in starting. Finally one day it did not start at all.
I took the battery to the dealer, who checked it out.....bad cell.
They gave me a new battery under warrantee, for a very small
difference. When I purchased the car two and a half years ago, the
original owner was nice enough to have installed, a new heaviest duty
battery in it we could find.....so who would think that "new" battery could
be bad....but it WAS.
I reset the clock and for 6 months now it has been running perfectly.
And the car starts quickly now! Apparently the low voltage when I started
the car would not run the clock for that period, so it was always
"OFF". In my "other" hobby of ham radio I have run into problems
created by voltage drop many times and am still kicking myself for not thinking
of it sooner.
