location of ignition coil ballast resistor
thanks for the help. I'm still wondering if i even have the resistor wire on my rig, i check the voltage at the coil positive lead and it showed 12 volts. My truck also idles rough but all the plugs seem to be firing, so i have a theory that the high primary voltage arcs across the points when they open preventing the coil from firing. anyone have this problem before?
