[urq] ignition cutout ad infinitum, ad nauseum

[Ed Kellock]

Decided to revisit this last night after dark with a spray bottle of
water (and a beer).

Started, spritzed, sat down to sip my beer.  The car ran perfectly
with no cutout and no arcing visible.  I let it run long enough to
cycle the rad fan a couple times, alternately letting it idle and then
rev'ing the engine.

Absolutely no cutout.

The last thing I did was to reconnect the spark plugs wires to the
cap, reconnect the wires to the coil, etc. after checking resistance
on all the various bits.

So there's something flakey there, but what?  None of the ignition
parts were within any spec stated in the IST doc (see below), but it
seems to be running now without cutting out and all I did was
reconnect everything.  The cutout seemed to manifest after I pulled
the cap and rotor a few weeks ago.  The cap and wires look like they
were a cheaper alternative at the time so I'll likely replace all that
with OE spec parts.  They were on it when I bought the car about 2
years ago.

As soon as I get my other little project wrapped up (fried wire from
fuse panel to ground point 13), I'll start driving it again and see
what happens.

Weird.  Prior to checking resistances and putting everything back
together, there was no way I was going to drive it further than up the
street and back.  A couple weeks prior to that when I pulled the cap
and rotor to clean up the contacts, it wasn't cutting out.
