1968 Lemans Starting Problem

[2Cool4Words]

melsg5 is correct that there is noballest resistor on the stock ignition switch on your car, but if figure 3of the mallory installation manual is how it is installed on your car, then yes it sounds like the ballast resistor may be bad. If one is installed. It usually looks just like in the drawing or this link

The location will be were ever the person installing it chose to put it. I usually saw them installed on the firewall, or near the Coil.
But if you trace the wire back from the coil to the firewall and do not find a ballance resistor, you may have a bad or miss adjusted ignition switch, or the linkage fron the lock cylinder to the gnition switch may be damaged or out of adjustment.
I have found that balance resistors can be damaged when jump starting a car that has one installed. I went thru at least 10 in my 74 dodge 1 winter. They would fail about 2 or 3 days after I jump started some ones car.

When the key is in the running position, I checked for voltage at the "RING TERMINAL CONNECTOR - PART NO. 450" that feeds power to the ignition control box and to the distributor and there is 0 voltage - not 8, 9, or 12 volts. In my car, the battery is connected directly to the starter and then I see another wire coming from underneath the car (presumably from the starter) that connects to the control module via the RING TERMINAL CONNECTOR. From this analysis, I now believe there's a bad connection coming from the starter to the control module since I'm not reading any voltage. The connection from the battery to starter to control module is not shown in FIGURE 3 but is shown in FIGURE 11 it shows the connection from the battery to the LONG RED wire on this attachment from Mallory: http://prestoliteperformance.com/media/instructions/mallory/Mallory_Instructions_hyfire_iiia_electronic_ignition_630.pdf

The only other thing that it might be as you said earlier is the connection to the switch in the car via the resistor wire. I have looked and looked for a resistor wire and cannot seem to find it. Should I attach some pictures to help identify it? Thank you again for your input

the resistor wire is connected to the ignition switch along with a second wire and both of them run to the positive side of the coil. Check the ignition switch with a voltmeter with the key in the run position. One of the wires will be hot fed off the post on the starter solenoid the other hot wire should be the resistor wire.

There is a resistor somewhere with points stepping the voltage down if not they will burn out , when switching to electronic ignition you need to run a new wire right to the ignition switch grabbing 12v in the run and cranking position as electronic ignition needs full 12v to run right.
