My experience and knowledge base on this should probably prevent me from chiming in but I will anyway. I believe in the KISS principal and Ricks (Ron's) solution seems to fit that process for a seemingly low frequency (though critical fail) problem. However, one must consider that the original sealed design did have a vacuum line.

BTW the plastic cap over the housing is not a good seal. So you
would not want to have a purging vacuum connected -- sucking in dust.
That's why a passive drain and that's sufficient.

In any case, I'd suggest everyone with a PinzSSI that gets into dusty
environments, take a look under the cap, and if anything it's a good
excuse to re-check your timing. If you don't want to plug holes and
add a tube then there's the Farmers fix -- put a zip-tied Freezer bag
over the entire assembly.

:lol:

In all seriousness, not as cheap as a plastic bag but for pop-up trail duty with a zip tie?

After removing and cleaning the timing disk and swabbing in the area of
the optical head, I decided to give it a go and drive my rig home from my
friends place, about 200'ish miles.

It still didn't run right but I got home. Yesterday I had some time to tear
into the issue more deeply and now I know why the problem occurred and
why it's not a quick fix. The PIX below shows the debris buildup on the photo
diode area. Note there are two slots, one for detecting TDC and another for
RPM/Accelerating. These slots are recessed, I presume to eliminate "cross-talk"
between the two channels. Being recessed it's vulnerable to dirt getting in
there effecting the detectors, it's a tight space obscured by the illuminator
and not easily cleaned with Q-tips.

What I ended up doing was to fill a syringe with Alcohol, squirt it in the
cavity area, then used my air compressor to blow it out. It took 4 tries
before I felt it was clean. An alternative would be an eyedropper, and a
can of dust blaster, or a electronics friendly ultrasonic cleaner. For good
measure I RTV'd the holes up on the underside, and placed a piece of foam
at the cable entry. On the trail I'll toss a freezer bag over the assembly.

If you haven't taken a good look yet, don't wait for this to be a problem on the
trail it's a huge PITA.

A piece of aluminum foil might be a simple solution. Cut a round piece and place it over the module, then form it to the shaft. A zip tie will hold it in place forever. The amount of dust that can get in will be minimized.

question to the group
I have the SSI gen 3 on my. I noticed that when I start off with a light foot on the gas I get a back fire pop in the air cleaner ( sometimes when cold) But when I am heavier on the gas no problems. I have set the timing twice according the instructions, is kind of normal. It runs great down' the road.
any advice
thanks

Well a couple of things come to mind. First when you went in there
a couple of times, did you notice that the timing had changed and
needed correction? If so, you may want to make sure your pinch
clamp is tight and/or the screw that locks the timing disk in place
is also sufficiently tight.

If your timing is not shifting, and repeatable, double check that you
didn't inadvertently set your timing 3-4mm retarded. A local Pinz
owner was telling me his engine didn't seem to be running well so we
checked his PinzSSI timing and it was set retarded not advanced,
apparently the previous owner was running it that way and didn't know.
After correction, he did note a considerable improvement in starting
and low RPM performance.

Stating the obvious....

I use a breaker bar on the crank pulley with a 27mm (or 1 1/16") socket,
turning the crankshaft towards the Drivers side -- the LED should lite just
a few millimeters BEFORE the TDC mark on the pulley (not after).

The latest version of the PinzSSI, the 4.0, is now available and includes a filtering system in the module that will keep most of the dust out, if not all. The 4.0 also incorporates 2 separate coils, one to fire cylinders 1 & 4, the other fires 2 & 3. Another difference is that the ignition comes completely assembled and ready to install, except for the plugs and plug wires. Performance and dependability is no different from previous versions.

The 4.0 also comes with a lead that supplies 12 volts for an accessory, such as a phone charger, radio, tachometer, or GPS, when the key is on. Total current cannot exceed 5 amps.

well ran though a mud puddle and my PINZ's started to cough and shudder for a little bit then started to run fine again after about three to five minutes. I got the Gen 3 SSI this is the first time tis has happen. the puddle was about 2' deep and going in third gear. Had to go back though it and this time went slower back though and then really cough and spudder. and thought why .

thanks

I presented your problem to management, and their initial response was to suggest fording deep water at a speed that produces little to no waves to keep water off of the engine. It's a Pinzgauer, not a Jet-Ski.

Engineering was brought into the meeting, and a design for a shield was drawn up and given to the fabrication department. This shield will prevent most water from making contact with open connections, assuming this is where the problem is. The Molex connector that feeds the fuel stop solenoids could have been affected by the impact of water, possibly shutting off fuel to at least one carburetor.

The coil and voltage regulator are water proof, and the module can only get water inside from underneath, which is impossible with the engine protecting it.

The shields are now at the powder coating shop and will be available next week. This will be standard installation in future 4.0 versions, those of you who want one for your ignition can PayPal $20 to pinzssi@outlook.com. Allow 10 days for shipping, and include your address with payment.

At PinzSSI we make results, NOT excuses!
