I am thinking it is the 7500 ignition box that cooked, not the coil or distributor.

Do you have a timing light and the specs needed to set ign. timing?
Why did you decide to replace the 'dizzy'? Did it test bad? Did you even have it tested?
Did you ever ck for fuel flow??
LG

Oh, when you say timing do you mean the order in which the cylinders fire, as stamped on the engine case?

I'm enjoying watching LG and Mike stumble over each other trying to help a Damsel in distress.

You two studs rock on.

I would next pull out a spark plug, ground it plugged in and crank the starter to see if you have spark.

I would also want to know what supplies the power to the 7500 box and would be checking out that circuits fuse.

Don't know who sells the box or how to test the pinouts on it. Maybe Google will give you a test procedure.

We actually tried that yesterday. That friend I mentioned came over and he did that test. I probably shouldn't mentioned it sooner...note that I understand where you're leading me. Anyway, no spark when we did that.

I gave you a link to the test procedure earlier, but perhaps you missed it.

Here it is again. Read the first two posts and follow the directions. You'll figure it out.

Hi Matt,

Sorry, I did see it. But I was getting pretty fast instruction from you guys and from my friend via text (you both pretty much had me do the same stuff...which was reassuring) that I didn't get a chance to examine it and then forgot about it.

So, after a bit of googling, here's what the 7500 box is (you probably already know, but I didn't):

Ok, so I read through that thread Matt recommended.

I think we've already done everything there:

1. We know the solenoid isn't the problem

2. I tested the other side of the coil (though I'm not sure if this is the right way to test it) - black probe to coil (-) and red to battery (+). Get 11.5mV.

But no spark using an old spark plug plugged into the distributor wire.
