Pertronix Ignition Install Questions

The capacitor at the side is nothing more than a radio noise suppressor so you may as well just leave it there. It wont negatively affect anything.

The kit instructions should tell you if you need an external ballast resistor or not although most electronic units dont need one. The catch on a MK2 is the ballast is built into the loom so the easiest way to bypass it is to run a new wire from the ignition switch to the + side of the coil and leave the factory wire disconnected.

Hi Matt
Leave the balast there, the coil will get hot if it is meant to have a balast resistor and doesnt

The Petronix thing is really only a swith or trigger so i cant see it caring if the coil is balasted or not

HI Guys,

I have installed everything but car won't start.

I have spliced the wires from the ignitor into the wires that go to the coil but they (the wires from the ignitor) aren't actually touching the coil itself.

Is this the problem?

I will change it so they are and see how that goes.

It's frustrating when things don;t just work straight away and you have to problem solve.

Just the joys of the home mechanic I guess.

Cheers

Matt

im confused about this part..
black wire goes neg coil, red to pos coil.
red/green on pos, pink [tacho] neg.
put new terminals on all wires and secure with nuts on the coil posts.

put new teminals on on to go over the coil pins.

is the pertronix air gap set right?

any corrosion on rotor cap or button?

any spark at all?

with all wires on coil, put key to "ON" and check voltage at the coil.

i think the air gap should be about 1.5mm? my kit came with a small flat bit of plastic which was to set the gap.
the ballast resister drops the voltage to the coil from 12v to 7v. it depends on which type of coil you use as some can only run 7v.
im not sure if there is any real difference between running a ballast resister or not.
if you dont have the ballast you may cook the coil.
it might be a good idea to buy a new Bosch GT40 /R coil. i picked one up from supercheap for ~$50 the 'R' model is the resister type.
also just wire the dizzy straight to coil, and run separate wires for power to the coil.

Did you get it to start?

Hi Matt,

Will email some pics thru to u shortly.
I have the same ignition system as you.
Something is a miss here.
Call me on my mobile if you get stuck.
