Hello,

Well after looking under the dash in the usual place (and unusual ones as
well), my trusty local garage found the verdamnt  "I.S." where it was supposed
to be, but covered and obscured by a dealer-installed hazard  warning flasher.
I forgot to look under it.....duh.  BTW, the Steve Laifman  seat removal pins
have worked great.
    Troubleshooting: my IS-governed gauges gave  strange readings. The temp
seemed to run high (on a hot day over 250  indicated even with Derale fan and
fan shroud bottom extension from Canada).  Fuel gauge was funky, reading OK on
the right or full end of the  gauge, but when it hit about 2/5 full, it
dropped to zero. My .IS,  under  test yielded 5 Volts and was of the newer
semi-conductor type. Got a new one  from SS and it measured 10 Volts
installed.
    With new IS installed I tested the temp gauge this  weekend in full
engine-running heat-soak. What had been 250 + was reading 195.  With the
electric fan running it goes even lower. Gas hasn't gone down far  enough to
report as of yet.
    Make note: if your fuel and especially temp gauge  read where they
shouldn't, check the Instrument Stabilizer voltage!
    BTW: I took the old IS apart and there are only 3  electronic components
inside: an NPN transistor labeled FZT651 and two ancillary  surface mount
components that look like either capacitors or resistors...that's  it.
One of the ancillary components is dead (hence the half voltage).

Hope this is of help to someone.......

Best regards,
Jim Armstrong
