Ignition problems, distributor

Hi,

When you say you have spark at the tower. Which component are you referring too? I assume you mean where the spark comes into the distributor. If this is the case then there has to be something in the distributor that is not delivering the spark.

The way this works is the primary coil get B+ and the igniter interrupts the signal which creates a voltage spike and this generates the high voltage needed for the ignition. The secondary then delivers the spark to the distributor through the coil wire and the rotor picks this up through the cap and as it spins it sends the spark to the wires then the plugs.

Let me know if this is where you are finding it and we can go from there.
