There is no ceramic resistor in our vintage AMCs. It's a resistor wire in the system, BUT I doubt that's the problem. More likely the 12vdc pickup on the solenoid burnt off inside (easy to test. Hook a test light to the I terminal of the solenoid with the wire off and it should light up when the solenoid engages. Surprisingly this is the reason for a lot of hard to start vehicles with this Ford type solenoid. Also try unplugging and replugging the ignition box connectors. A slight corrosion buildup is all it takes to cut them out. This is assuming motorcraft system & not Presto-no-lite. For troubleshooting you can hook a wire to the I terminal wire (with the key on!) direct to the battery and see if it starts (that bypasses the resistor and gives the coil and ignition box 12vdc direct) If you have the &$(:"€>% coil with the horseshoe connector, replace it with a Napa IC12SB (or IC13sb or IC12) for an extra kick for starting.

It won't start. When I release the key from the start position it tries to start and if I am lucky it'll fire, but the key returns to off too soon. I hooked up one of those spark testers and I get no spark while it is cranking, then when I release the jumper it sparks for an instant. I took off the batt cable to charge it as I wore the battery down cranking, and the car cranked for a second. Whats going on????....Russ -------------- next part -------------- An HTML attachment was scrubbed...
