Thanks Jon. No. I haven't checked that cap with my meter. I will do
so. Are you thinking that + power had back flowed through this cap to
the negative buss in the ECU? Forgive my terminology. I don't know
that much of electricity and electronics.

Since I now consider that ECU non op, I did measured continuity
between the exposed copper trace and various points. That trace shows
continuity between ECU 1 (main negative ground connection) and the
metal frame. It's obviously a ground path.

My only real concern is that any small wiring details I'd previously
gotten wrong in the harness, might've caused this issue over a period
of time.  (i.e. I hadn't connected a "sensor" ground. The engine ran
ok though) From what I'm understanding though, that likely isn't the
case.

Neil.
