I'm rehabing my old '90 Chris Craft Limited 245....I/O...350
cobra...runs great.. I'm- basically redoing all of the front end
wiring, instrumentation and breakers (was in **** poor condition when
i got it). I have the instrument panel on my workbench and I'm wiring
up the new instruments....daisy chaining the Ground, the Ignition, and
Light terminals. Checked my continuity between the instruments on
each line (G, I, L), and of course since they are all daisy chained, i
get continuity. Great, that is expected. What isn't expected is
that i am getting continuity across the G, I, L, and S terminals on
the instrumenets, including instruments right out of the box with no
wiring hooked up to them. This doesn't make sence that this would
be. I wired everything up and tested my lightning and even though it
appears there is a short across the terminals, the lighting works.
The majority of my instruments are Teleflex, if that matters.

Any suggestions??

What Ohm scale range are you using on the meter ?

You are reading the resistance of internal components... Increase the meter
scale range to highest and see what you get... I'll bet it is not a dead short.

i'm getting about 70 ohms between IGN and GND, 1 ohm between LGHTS
and GND, 70 between LGHTS and IGN, and about 85 between IGN and SNDR.

The only reading that could be called anywhere near to a "short" is the
LGHTS-GRND. That will be meauring the resistance of a light bulb. Why don't
you remove a bulb and check it specifically.

Personally, without knowing the specific instruments, I'd say everything is AOK.
