I am impressed by how a person's big ego can prevent him (or her)
from showing appreciation for a good idea.

An intelligent person who might not be able to develop a better
method, but who can at least recognize one when they see it
(someone who is not inhibited by his own big ego), might notice
the benefit of using a method that does not require tools or ties.

Take a wire of whatever sort that is about 4 feet long. Fold it in
half. Fold it in half again. Now it is 1 foot long. Grab both ends
and tie an overhand knot. That's it. It stays stuck together in a
much more compact and easy to manage form.

Besides...
My occasional/rare original post does not make me a troll. I do
not nym-shift. If you want to avoid "feeding" me, use your
technical expertise to set up a filter that ignores me and all
replies to me, or to simply press the ignore-thread key.
Otherwise, you are the troll. Or in Jim's case, he uses the
opportunity to act above it all while spamming his business.

Its starting to get a bit flakey. From time to time (and more frequently
now) the ignition just cuts out. Just like turning the key off. But it
still has +12V to the coil. After starting the replace parts until its
fixed method, I'm down to the solid state module now.

But, and here's the puzzle, one of my diagnostics for spark/no spark has
been to throw an old timing light on to the coil output. Oddly enough, that
fixes the problem within a few seconds. The engine fires up and runs fine
for a few days. Otherwise, its crank, wiggle wires, poke around with a
voltmeter to no effect.

At first, I figured that too large spark plug gaps were causing the coil
secondary (and primary) currents to decay too slowly and that this was
screwing up the module's operation (bad flyback diode perhaps?). The
addition of the timing light was like putting a gas discharge surge
arrester in the circuit, clamping the primary voltage quickly. But this
failure continues after having changed plugs, cables, cap, and rotor. New
coil too. So everything should be within spec. And when it runs, it runs
beautifully.

I'm pretty sure its the solid state module that's got to go*. It's the only
old part left. But I'd like to understand the cause behind the failure
while I fix it. And this is an interesting puzzle. BTW, the module is
potted, so I'm can only guess about its innards.

Any thoughts?

If it's the old grounded collector kind with a high voltage PNP
Ge-transistor in there it could be that the capacitor in the module has
come loose. It's usually the same kind that used to sit across the
points before they went to transistor ignition. If that's the case you
could try hanging such a cap from coil minus to ground, in parallel.

Also, check the points. See whether there is dirt or gunk in there.
AFAIR with old transistor ignitions the voltage flies up with the coil
minus voltage.

*A replacement is $350. I'm pondering building a DIY unit from scratch. With
a few test points brought out as well. I've found a few DIY projects on
line (including one with the obligatory uC).

It could be done sans uC although that doesn't have the right coolness
factor these days. And don't forget that big blue flashing LED

The FJ40 is a nice 4WD. A friend has modified his and put a Chevy engine
in it, he now calls it a "Chevy-ota".

Whitney used to sell after market electronic ignition kits. Not the
Bumble-Bee stuff. These had a Hall-effect sensor that went into
the distributor and an external unit that drove the coil. I haven't
seen a Whitney catalog for years: they are still in business:

Usenet. You gotta love the kooks.

Go back to the kook group, you retarded fuck. You will never be loved,

K0TAR A complete and utter retard.

He really likes the word "retard".

Wonder why?

He also loves fecal references. An expert in Scatology.

Troll feeder.

Guilty as charged.

(Hmm... or perhaps a Fecologist?)

The FJ40 is a nice 4WD. A friend has modified his and put a Chevy engine
in it, he now calls it a "Chevy-ota".

Considering where Toyota got the original six cylinder engine from... <bg>

I have an old Toyota FJ40 (1979) with 'transistorized' ignition. A
reluctance pickup wheel in the distributor and solid state module to
switch
the coil in place of the old points.

Its starting to get a bit flakey. From time to time (and more frequently
now) the ignition just cuts out. Just like turning the key off. But it
still has +12V to the coil. After starting the replace parts until its
fixed method, I'm down to the solid state module now.

But, and here's the puzzle, one of my diagnostics for spark/no spark has
been to throw an old timing light on to the coil output. Oddly enough,
that
fixes the problem within a few seconds. The engine fires up and runs fine
for a few days. Otherwise, its crank, wiggle wires, poke around with a
voltmeter to no effect.

At first, I figured that too large spark plug gaps were causing the coil
secondary (and primary) currents to decay too slowly and that this was
screwing up the module's operation (bad flyback diode perhaps?). The
addition of the timing light was like putting a gas discharge surge
arrester in the circuit, clamping the primary voltage quickly. But this
failure continues after having changed plugs, cables, cap, and rotor. New
coil too. So everything should be within spec. And when it runs, it runs
beautifully.

Are the plugs gapped right? You might just want to clamp a neon lamp
across the coil, to simulate the timing light.

I'm pretty sure its the solid state module that's got to go*. It's the
only
old part left. But I'd like to understand the cause behind the failure
while I fix it. And this is an interesting puzzle. BTW, the module is
potted, so I'm can only guess about its innards.

Any thoughts?

*A replacement is $350. I'm pondering building a DIY unit from scratch.
With
a few test points brought out as well. I've found a few DIY projects on
line (including one with the obligatory uC).

No junkyard parts available? That would be my first choice.

=======================================================================

Bosch made a range of "universal" ignition modules. I'm sure hunting around
you would find one for much less than $350. They were black about 75mm x
25mm 8mm thick with 5 or 6 terminals along the front edge.

They looked like these:

The basics of a very good method, which uses a standard ignition
coil...

http://www.analog-innovations.com/SED/Self-Inverting-CD-Ignition.pdf

The control system is around somewhere... on paper... pre-CAD ;-) It
measured the current in the emitter and the base and calculated IC (HV
transistor beta was ~4 at 5A

This was circa 1972. Modern circuits elements will make it easier now
than then.

Shown previously while arguing with El Dorko... the 5mH, 5 AMP, yes
AMPERES, inductor for my CDI ignition...
