Hey Mark, if you are determined to replace the MSD box, let me know.
I could use another one.
I had one factory rebuilt recently and it is less than a new one, by far.

I already have the replacement box. I upgraded to the digital version. I'll get back to you via PM once I get the originial one out.

OK well that kind of wasn't as painful as I thought it would be. The two stainless screws that I couldn't reach the nuts on the back side drilled out reasonably easy. The bottom two screws holding the MSD unit to the firewall only took some contortionisum to get off by myself. And I was able to pull enough wire out through the firewall to leave a usable length on the box itself. The power wires were easy to pull out as they were exposed and not hidden by the Heater. The White wire which I have no idea what I hooked it up to (most likely a ground) is not coming out of the hole so it must be hooked to something. The Orange and Black wires that I had hooked to the coil came right out when being pulled off the coil and out of the firewall. So now I just have to figure out which Red wire going to the ignition switch is the one I need to replace and split to the MSD unit and to the Petronix trigger. The Tach drive wire will be an easy reconnect I just need to cut the wire from the MSD plug short put a spade connector on it and plug the wire into it. easy peasy.

I am thinking on getting one of them threaded blind rivet installers to create anchors to mount the MSD unit to so I don't have any trouble removing this one. Should I ever need to.

Being its Sunday and the real tool store is closed I'll end up with the threaded insert rivet tool from Harbor Freight. should work fine. Only it uses 10-24 inserts instead of 10-32's like almost all my other small screws. Just have to keep that in mind.


Should have this all squared away today then I can test and see if the Petronix unit still works, If it does I will be ready to attempt to fire up the engine.

I hate only having Sundays off. I get up at 4am to have a full day to work on CHUG and of course the 1/2 dozen other things I have to do. I am trying to finish up the wiring for the new MSD ignition box. And I find that I don't have any of the right size of Heat Shrink tubing to finish off the terminals. SO here in Silverton that means I have to wait until either NAPA or ACE opens up 9am in the mean time (its now a bit before 7am) I am on hold.

SO looking forward to Memorial Weekend so I can get CHUG started and on the road. I was hoping to have everything ready for the start up. Starting to wish it hasn't been so long since I primed the oil system.

I find it hard to imagine an auto parts store or hardware store that doesn't open up until 9 o'clock in the morning. The local NAPA parts store opens at 7:30 every morning except Sunday and doesn't close until 6 o'clock at night...unfortunately they are located 15 miles away...

Got it! Sunday...I'm retired and sometimes the day of the week doesn't register in my mind.

Although I would never make all the mods you have attempted on my "Ol' Red" I find your project very interesting as a retired machinist. Your design and execution of various parts of CHUG are exceptional. You will get CHUG running soon and you are to be congratulated for your attention to detail and perseverance.

Well the little RED LED comes on when I turn the Key on which according to the MSD instructions that means the unit is correctly connected.

I now need to replace the in the wall AC unit that went to crap last fall. With the new unit the wife just brought home from Home Depot. once that is done I can put the ignition switch back in the dash and get the wife to help me see if I have spark.

If I have spark I think I am ready to put some fuel in it and see if it will run.

If no spark I need to swap out the Petronix Units. I am hoping that since the thing was hooked up completely wrong it never had enough voltage going through it to hurt it.

If no spark I cuss a while and know what I am doing next Sunday.


I'm going to make a little aluminum fence to protect the new wires where they come through the firewall just above the top of the Pass Toe Board as they could be kicked and damaged.

I now have everything set up so that any of the parts in the Ignition system can be swapped in less then an hour as long as no damage happens to the harness. As it was before had the MSD gone out it would have been a nightmare even to by pass it. Now I can do that just by plugging in a couple jump wires.

WELL here I sit. With no spark.

MSD has a test to see if the spark box is working. You pull the Coil wire from the distributor and hold it .5" from ground. Then you ground the White signal wire (the wire that comes from the points or in my case Petronix trigger) You should see a strong spark.

I got that.

but when trying to get spark with the Petronix as the trigger nothing. SO I assume the Petronix unit got fried when it was hooked up wrong.

So next Sunday I get to swap that out.

Least I know the Toyota starter works LOL. Turns the engine over well with no gear noise what so ever.

I had a 6AL on my old Nova and used the points to trigger it. I drove it a good 10 years on one set of points. There is so little current that the points don't wear.

Exactly what I was going to say.
Points can still float if you wind it up far enough, but they won't burn at the very low current they see.
All they have to do is trigger the MSD.

Good grief got the new Pertronix unit installed and it won't trigger the MSD. everything is wired correctly. I checked all the grounds and they are good.

I give up.

I have the Points plate reinstalled. And as soon as the wife is at a point she can push the starter button I'll give it another try.

This has been one of the more frustrating things connected to this build.

I have ran this exact ignition system on two other vehicles and never had any trouble like this.

I'll be back once it makes spark.

Then I can go out and hump the huge pieces of Maple tree the wife had the guys that do her yard work dump right in front of the doors to the Jeep shop. So I can't get Chug out of the shop until they are moved. ?????

At least I can open the doors to see if I can get it to fire up.

The good news is that the MSD will be quite happy to be triggered by points and they will last forever doing that.
Why the Pertronix won't work is a mystery.

Well after three Sundays of beating my head against the wall.


I HAVE SPARK AT THE PLUGS

this last PITA the Points that were installed in my OEM distributor as well as the set of NEW NAPA points did not conduct electricity across the points!!!!!! Two bare metal contacts and NO passing of juice.

Went to NAPA and the Kid found some other application that the points were close enough to fit and I just finished installing and testing them

So as to not drag the wife away from her project again. I just set up my phone to video record the plug I had laying on the head and sure enough I got a couple sparks across them,

Now to have lunch and start cleaning up the huge mess of tools and crap that I haven't done anything about for three weeks.

OH and get the battery back on the charger. SO hopefully next weekend I can start this thing.

I'll revisit the Pertronix unit at a later date, but I think for now I will run with these points.

OH MY GAWD

CHUG ROARED

I put a little gas in the carb and hit the go button and I got back an immediate deep throaty roar with no hint of back fire or anything. SO I feel really good about actually starting it up tomorrow when I have some help just to watch things.

It was a very very good ROAR.


Funny thing it I wasn't even supposed to have today off. While the FEMA clean up job we have been working 60+ hours a week was taking four days off the co. wanted to get a paving job done today since they would have some trucks available. I told the dispatcher I had a DOC appointment this morning and he decided it would be easier to just give someone else the work.

SO I was out in the shop trying to finalize things for starting the engine tomorrow and I just thought why not try a little premix chainsaw gas to see if it would fire. AND IT DID.

And now I get to fix all the things that have popped up.

Manifold stud leaking (done I hope)
Carburetor float not working (done or so it seams)
Wiring circuit to the electric fuel pump not working even though it was tested during the wiring phase. The pump works if I jump the relay so its something in the Oil Pressure safety switch side of the circuit. Thats this afternoon.


Can't wait to find whats next. And of course when I drained the coolant to fix the manifold stud the crap went almost everywhere but the catch pan.


On a good note on one of the attempts since the car was flooding the engine ran long enough to show a solid 40psi on the Oil Pressure gauge.
