Ignition (Pertronix) Question

Postby boxfullofyertoys » Fri Aug 01, 2008 9:56 am

Hey everyone...here's my situation:

I just recently acquired a 1976 Midget. From what I can glean from the title and the hardware on the car, it was imported into the US from Canada...so instead of having electronic ignition, it was a standard points/condenser type. When I got the car, it started and ran, but there was a miss somewhere...did the plugs, wires, timing...rotor and cap were suspect, but then I noticed that the distributor shaft had some serious play in it and was probably the culprit. I decided that instead of a full stock replacement with points, I'd order up a Pertronix flame thrower disty...

Long story short I installed it yesterday and I've confirmed the coil isn't throwing ANY spark. I suspect the coil is dead. I'm going to test the coil when I go home on my lunch break (one of the perks of living 2 miles from the office :D ), but I have this fear that I may have fried the new disty by using the stock (what I believe to be) 1.5ohm coil. Can anyone shed some light on this for me? Should I be using the stock coil or should I be running a 3ohm?

Any help would be great...the next round of parts arrive on Monday and I'd like to have the car running so I can effectively test the new brakes, and go for a ride, of course lol

Thanks!
-Dave

Pertronix recommends the use of a 3.0 ohm coil for a 4-cylinder engine for normal driving, and a 1.5 ohm coil for racing applications.

I do not know if they recommend an external ballast resistor, or not.

Also, their ignitors are available with positive or negative ground designs, and must match the car's electrical ground polarity.
