I was witness to the scrapping of 4 crates of military vehicle parts from canada....long ago....the one i helped unpack was marked 11000 lbs. .....almost all the parts went to a dumpster headed to the dump....such a waste....long story....maybe another time....

Happens all the time. Sometimes good reasons, sometimes not.

It has been awhile..
At BenzWorld I had started a thread about a retrofit Capacitor Discharge Ignition without distributor. This was based on inexpensive CDI modules for ATV and such. The ignition coil pack comes out of a Ford F150 V6 pickup.
Bought an extra CDI module to reverse engineer and destructive test.

Then I tested it with the Ford triple ignition coil setup. That is on one coil (of the three). In the picture it is running at 3600 rpm camshaft so 7200 rpm crankshaft. ( spark plugs left bottom)

I milled the bottom out of the potted CDI box so that I could see the backside of the PCB and reconstruct the schematic. With a Dremel I got access to a couple of critical solder joints to take measurements. With a small modification this now runs on 24 volt directly... Tested for an hour at 32 volt and 7200 RPM.

Then from an old photocopier I had some optical gates. By chance three. So that worked out. In the scrap bin was an aluminum ring that I modified to hold the three optical sensors.
Instead of going with another distributor I figured to use the old one and leave the points and all in place so that I can switch back to all original in a couple of minutes..... and of course save cost.
The next part is making the vane that actuates the three optical sensors and doing an actual test.

This is of course all proof of concept.

When i got my mog it didnt run exactly right....i will bet you i removed and cleaned the carb....oh lets say a hundred times....ill bet....then found a guy with a yard full of old mb cars....bought a distributor complete wires ect....never ran better....i never took the time...or had the brains to figure out what was wrong with the original parts.....you can take the ignition to a more modern level....very interesting....more power to you mate.

Yes this carburetor stuff is a lot of touch and feel.. I am sure mine is just hanging on its last legs...

Did not have a working hood stick.. I assume the one that was on there is not original.. Either way a M8 stainless bolt has resolved the functional part.IMG_20200616_174229_790.jpg

Thank you David, when I got this mog that hood bracket was inverted and it sat on the bracket that holds the air intake. Did not make a whole lot of sense so I flipped it over. There is a really flimsy hood bracket on the driver side. This hood has already some fatique cracks that I need to address.

Thought to not handle heavy equipment today after my running in with a breaker bar. The rotted door from the Mog caught my eye. Keeping momentum is important so here it is.

A piece of stainless from a postal office stamping machine up cycled to mog duty. It had one nicely set 90 degree angle.. Cut out what I needed .

Inside the door is a reinforcement lip that was rotted away as well.. Could not make that since I do not have a brake. So I decide to make a second angle on the piece I had..that is with a hammer.

Some corner and edge modifications and some straightening from my hammering job . Then I tacked it in for a first look.IMG_20200620_170351_997.jpg

About beer time.

Hiha, the title came in. She is legal. Still need to fasten the horn. Since this was a civil defense unit there must have been more horn on it but they have disappeared. wiring is still there.
The remaining horn is hanging loose. Anybody has a picture of how it is attached?

Thank you,
Johan
