Testing Shielded Conductors?

The shielded conductor pin/wire #3, at ignition amplifier 146 (lower
left), has a some surface corrosion, as it's strands wrap around the
insulation of wire 653 (from pin #5), at the 146 connecting harness.
Both the shielded conductor and wire 653 disappear into a wiring harness
(which I'm willing to cut open)

Would it be correct that the shielded conductor has no continuity with
wire 635, and that it just "starts" as "a wrap" on the wire's insulation
at some point up in the wiring harness?

i.e., how do I test that the shielded conductor is good?

test for a path to pin 3 from the other end of the sheild, also check to
make sure the sheild isn't shorting to pin5. Is this on a SAAB or Volvo? In
all likelyhood you need a new amp, they commonly die.

Okay. Will do. So assume the other end of the shield just "starts"
somewhere on wire 653. I'm leery about just using a continuity ck, but
perhaps that suffices for shielded conductors

And I was uncertain what's it's function was wrt plugging into pin #3 of
the amp
also check
to
make sure the sheild isn't shorting to pin5.

Did ck and it's not
Is this on a SAAB or

Sorry - I should have stated. It's a 91 Saab 900S

I've tried different amps w/o change, so am digging deeper into the
wiring (amongst other ignition components and wiring)

Thank you
