First, why on earth did you have a spark plug lead on a radiator
cap??? (presume you meant 'distributor' cap?)<br>
<br>
It looks like you have your multimeter set to diode test (maybe
that's how continuity works on your MM?).* The reading is probably
ohms, indicating a very low resistance circuit, but to be sure turn
the MM control knob one click clockwise, to the 200 ohm range ('200
omega').* It'll probably give the same reading; i.e. .792 ohms,
which is about what you'd expect from a short stranded copper wire
lead (IIRC, one ohm per foot of cable is considered normal, even
copper has some resistance).<br>

Hi guys,
<div class=3D"">Educate me. When doing some preventative
maintenance, I pulled a spark plug lead out of the radiator cap
(using a 123 distributor) the cable pulled away from the
terminal - not a particularly unusual outcome. Got a new 90
degree terminal and crimped it on to the cable (Pertronix cable)
and before I put the boot on the end of the cable I thought I
would check the continuity. It barely dropped below 1.</div>

<div class=3D"">So then I checked a brand new, never used, cable
made-up by AH Spares. As shown in the image below when the
sensors are attached to each end of the cable I get a reading of
.792 which is not sufficient to even sound the beeper on the
multimeter device. I suppose there are degrees of continuity
(not just on/off) but I guess I expected the alarm to sound and
the reading to drop to near zero.</div>
