The electrolytic cap suggestion has merit. The cap fails under normal
loading, but heals itself when left to rest or when the load is increased
by adding the strobe light.
Its a puzzle I'd like to solve, even if the fix is just to replace the
entire module. Its potted, so its probably a goner anyway.
That's a coil on plug retrofit, if I'm not mistaken. And it still needs an
ignition module to drive it. I'd rather stick with the OEM coil and
distributor. The Landcruiser setup has a few design features enabling it to
work submerged and I'd hate to go to a standard automotive setup not built
with rugged environments in mind.

If your only tool is a hammer then every problem looks like a thumb.
Exactly. I just can't figure out what its 'fixing' and how. And what, left"Paul Hovnanian P.E." <paul@hovnanian.com> wrote in message

You
say you've replaced everything. Does that include all the HV wires,
dist cap, rotor, coil, and plugs? All of those together are cheap
compared the ignition module.
Yes. New coil, wires, cap, rotor, plugs. Although this is an all on/off
problem, so its doubtfull all the plugs would fail simultaneously.
Agreed. Having ruled out everything downstream of the ign module ...
The only electrical effect I can think of is that the timing light added
capacitance to the coil output. This got reflected across the coil and
"fixes" the ign module.

Have you considered going to an aftermarket
CDI? This is the first one I found and it's considerably less than the
OEM module.
