instrument cluster voltage stabilizer [was: Re: Coupe GT fuel gauge adjustment]

[auditude at get.net]

Hi again,

['86 Coupe GT]

Well apparently I didn't realize the relationship between my
low-reading water temp gauge, and the low-reading fuel gauge.
I thought they were two separate issues, but it's likely they
are not.

Tony Lum gave me a heads up, which I didn't get until later,
about the voltage stabilizer device that is apparently located
at the back of the instrument cluster.  Apparently this is
where I should focus my attention for this problem.

I found some references to dealing with the voltage
stabilizer, but I didn't find anything that described what to
do if there is something wrong with it.  Is this a situation
where the bad part simply gets replaced by a new one?  Or, is
there some refurbishment that is possible?

Thanks,

Ken
