Classic/Antique Car Repair: 1968 Chrysler New Yorker electrical problem, ballast resistor, chrysler new yorker

Question
I have a 1968 Chrysler New Yorker with a 440. I have a intermittent problem with starting the car. When I turn the key to run and the dash lights come on, i can turn the key further to crank the motor and everything starts and runs well. Sometimes I turn the key to run, or the on position and i dont get any dash lights, when i turn to start the car there's nothing. However I have power to my power seats telling me that I have power. I've replaced the ignition switch, starter relay, checked the connections...So I'm lost can you help? Also some forums suggest replacing the ballast resistor.

Answer
Hi David:
I'm assuming you check the battery terminals to make sure they are not corroded or loose. A loose cable could give such intermitted results. If you have check out the battery, then there may be a short in the wiring. Also driving in the rain recently could have gotten certain wires and relays wet. Allowing a few weeks to dry out could solve the problem if water is suspected. More feedback is needed.
