RE: [alfa] The gauge that cried wolf

["Jeff Greenfield" <alfaguy@xxxxxxxxxxxx>]

If the gauge is pegged all the time, it is possible that there is a short in
the wire between the gauge and the sender. Although it is possible that the
sender has shorted, I have never seen this mode of failure in 20+ years of
working on Alfas.

Disconnect the wire to the sender and turn the key on. If the gauge is still
pegged, there is a short somewhere. Probably behind the dash right at the
gauge ... the wiring back there is generally a mess.

If the gauge drops to zero with the wire unplugged, then the sender has
shorted.

HTH,

Jeff

Hey Alfistimostis!

So my oil pressure sender has finally bit the big one (either that, or
I have a very serious problem). This got me looking into getting a new
set of auxiliary gauges and I was wondering: Is it possible to retrofit
VDO or some other good brand into the Jaeger faces? I don't need the
numbers to match perfectly, as long as I can know the accepted values.

Otherwise, I'm gonna have to build my combined gauge cluster/equalizer
in the glovebox. And you KNOW how I hate purchasing frivolous audio
equipment.

On an unrelated note, what does it say about my vehicle when a gauge
pegs and I immediately blame the gauge, rather than the problem about
which it is screaming?

TIA
