If none of the gauges work, it sounds like a power or ground connection
that's common to the whole cluster. There's also a little metal box that's
a voltage regulator for the cluster. Yours may be roasted...

I've noticed that sometimes mine get firmer after bleeding till I'm
bleeding but can't get it all out too. My bronco has been mushy from
day one and the other day a made a panic stop and now they are much
firmer. Maybe it's the additional pedal travel that allows more room
for the bubble to get out or the pressure forces the bubble past the
seals in the MC, don't know but I'll take what ever I can get :-)

I explain by saying I don't agree with this statement. You want as much
advance as you can get at idle, so I say start by using manifold vacuum. I
know I am going to have to get into a big discussion again here because a
lot of folks don't really know the difference between ported and manifold
but I'll assume for now that you all do. So, as Gary pointed out, since
the mixture is fairly lean at idle and there is no load, maximum advance
will make your engine more efficient on fuel here and run cooler to boot.
So you start out with manifold and see if you can use it. The thing that
would prevent this from working out would be if you cannot then lower your
idle speed enough to keep the engine from running-on after the key is
turned off (since the added advance has now increased the idle speed it
must be adjusted to spec). If this is the case then you go to ported
vacuum but this is the only situation that I can think of why you would
wanted ported instead of manifold (and if it was me I'd try to slow the
engine down first by leaning out the mixture and see if that will help
before you give up on manifold vacuum).

Which way should the clothespin be pointed? Towards the engine

so maybe "heat sink" is an incorrect term in this context. Maybe
more of a "heat collector." The wood would be more resistant to the
environmental heating that's affecting the metal fuel line, allowing
it to absorb the heat from the metal line that it's in contact with.
Or something like that. At any rate, it has to be *somehow*
related to heat transfer, if it really works (no firsthand experience),
because otherwise we're talking about alchemy or mysticism or
something.

The old method before someone figured out how to make the cable go on
the outside of the column was to mark the wires or write down the
colors and positions in the plug and take a thin, small screwdriver
to release the pins in the plug and pull the wires through.

Then you install the new switch, run the wires down and and re-insert
the pins in the plug. If this is what's messed up you can do a
search and destroy by trial and error with a helper to watch which
lights come on when and figure the wires out. There are two power
wires (usually blue), one for brakes and hazzards and one for signals
which is only on when the key is either in acc or run position so
find those first and use them to test the other circuits.

To which Deacon replied:

I agree. OK, a quick test - pull the wire off your temp sender. Attach
it to a nice, solid ground. Turn the key on, the temp gauge should peg
on the high side. If it does, replace the sender, if not look elsewhere.

} Each gauge will more than likely have one wire that is common to
} all three gauges and that would be the wire that is giving you the
} problem. The common wire would probably supply power and the other
} supply a ground by connecting to the sending unit.

Listen to our Deacon! He can Help! Trust the Deacon :-). Fuel, Oil,
and Temp gauges are powered by an 'Instrument Regulator' The regulator
takes battery voltage in (10 to 15 volts) and regulates down to a lower,
constant voltage. That way as the battery / charging system voltage
changes, the gauges won't move around.

} To test this you could check the common wire for current. If there
} is no current trace the wire back to where it originates. You may be
} able to fix it by running a wire from where it originates or has power
} to where it connects to the instrument panel.

Now, in the vintage of trucks close to our hearts, this regulator
is a 'chopper'.If you look at the regulator's output (voltmeter or
testlight), you'll see it jump from zero to about 12 volts, switching
at about (guess here, haven't looked for a long time) a once per
second. Your gauges see the time average of this voltage. As the
battery voltage goes up, the chopper will slow down, ensuring that
the time-average voltage to the gauges remains constant.

} The continuity of a sending unit varies which enables it to move the
} indicator. So it wouldn't be possible to give you a unit of measure
} for testing.

Yup. The resistance varies with (temp/pressure/level), which varies
the current through the gauge, swinging the needle.

Ammeter? Well, that's different. Steve D. did a real nice job on this
last fall, somewhere in the archives. He even taught Deacon about Ohm's
law :-) Anybody save it for reference?

You can get them directly from Helms Publications, automotive dept.
and the price veries from $50 up to more than $100 if they are still
in print. I had to go to Faxon to get mine and it was a used set
which they reprint portions of etc. for $120 (for a 78 truck set).

There are a bunch of book sellers who carry the used ones and can get
them for you but I lost the list I had so Faxon is the only one I
know of off hand.

Then you get an electrical or vacuum dashpot to hold the idle speed
which collapses when the engine stops or the key is shut off, closing
the throttle plate completely which prevents the run on problem AFAIK

And just how do you think I learned that little trick, Hmmmmmm?
You're right though it doesn't always work so my next step is usually
to remove it altogether and hard line the dang thing........:-)
Every time I tried to move that little pin it didn't seem to do
anything but usually they just fix themselvs after a while so I never
worried about it much as long as it would stop when I pressed the
pedal :-) Always figured that light was for sissys anyway :-) (real
men could tell when they needed some work)

Only time I needed to worry about it was waaaaaay back when we had
inspections by the state police and they had this really bad attitude
about that stinking light........:-( (so I usually disconnected it
:-))

I always pointed mine north but that was kind of inconvenient when

change..................:-)
