Hi all. I have a 1966 Mustang GT, yesterday I was "attempting" to swap out my points for an Ignitor II system. Well something went fubar because now the engine turns but will not catch. So I changed everything back to points, and still...same deal. I'm curious if the coil may have gone bye-bye so I bought a new one (comes this week), I was wondering what else it could possibly be. Could it be a timing issue, but if it were wouldn't the motor fire but be rough?

Any advice is appreciated, thanks all!!

how do I determine the high lobe?

If you look at your distributor cam it is not round it has corners (high points). The arm has to be resting on a high point in order to set the gap. You can do that by bumping the engine a little and checking.

Here is a link that'll help you out.

Yeah if you reverse the wires that will fry the coil. I had the Pertronix system on my 68 for about a year and then the electronics went up and almost left me stranded. I went back to points for the amount that I drive the car and it is running better in my opinion. I had to really advance the timing to get it to run right on the Pertronix ignition.

Thanks so much, I actually thought that was what was needed but wasn't sure. Thanks again!!! I really appreciate all of you taking your time with this!!

No problem that's what we are here for. :btu:

Dang, well that wasn't it. Good thing I have a "hit man" coming up Sunday to help me :bows:

Funny part was, the points would arc, and they were set right on the high cam lobe. I checked for the .017 gap multiple times...did the go/no-go test and even put a new cap on and re-ran the spark plug wires. My wife (who use to build import motors for the track) said it could possibly be a dead alternator. The AMP gauge was bouncing prior to this, not sure if that could cause it not to start :confused2:
