Re: won't start please help
the spark coming from the coil should be hot enough to arch an inch or two when holding the coil wire close to a ground. It will only arch when the points or in this case the petronix ignitor fires it. You should not use a test light to check the coil center lead. Coils put out thousands of volts and if it is firing right it will burn the light out. The way is works it this. You have voltage to the coils + lead. the ingitor applies a momentary ground to the coils - lead this fires the coil. The timing is adjusted so that the firing of the coil happens at the correct time and it sends the spark through the rotor to the correct spark plug. I have an ignitor one. You have to supply a full twelve volts to the red lead coming out of the distributor. If you have it attached to the hot lead on the coil and you are using a resistor wire you are not getting a full twelve volts to the ignitor. The black lead coming out of the distributor attachs to the neg lead on the coil The gap between the ignitor and the magnet on the distributor needs to be 30 thousands of an inch for it to work correctly.
