The truck is not here ..heading over there later. Truck is positive ground, new coil and points, power to coil when key is on. I suspect something with the points (grounded?), nothing I have worked on before but (1) distributor (2) distributor caps, (2) sets of points, (1) coil on top. Understand that someone installed the points and now no spark, hench the new coil...any special procedure setting up this ignition? They have a condensor mounted on the outside. Thanks
If you have power at the coil (-) terminal, your ignition is probably fine because that's where the coil's power comes from. Check if you have power at the points. Check the ground wire on the opposite side of the coil (+) terminal, and follow it to the distributor. The wire frays inside the distributor and grounds out the moving plate. This causes a no-fire situation at the plugs. All the plugs. When checking the coil be sure the points are closed. Does the coil have an internal resistor? Or happen to have any other resistors wired into the ignition system? A 6 volt coil will run for a while on 12 volts then fail. Use a 12 volt.
