geniv Posted March 15, 2009 Share Posted March 15, 2009 I found some wiring from ignition switch to firewall whichhave melted. Someone ran a new wire from switch to positive side of the coil and added a ballast resistor in this wire. This resistor now gets hot when the car is running.I have a new harness from a parts car that I want to install, but I am afraid the wiring will get hot and melt if I remove the ballast resistor. Any thoughts Regards BarryROA# 10622 Link to comment Share on other sites More sharing options...
jrbartlett Posted March 15, 2009 Share Posted March 15, 2009 If it's any help, I own a '64 Lincoln convertible that back in the 70s had an under-dash wiring fire when my late mother-in-law owned it. According to the parts book, there was a ballast resister wired into the ignition system between the coil and the ignition switch. When the dealer repaired the damage, they apparently eliminated the resister (which may have been what caught fire, but I don't know for sure) with a high-resistance lead wire from the ignition switch to the coil. This wire gets warm when the car is running. I've run the car on the present setup for roughly 100,000 miles over 25 years. Link to comment Share on other sites More sharing options...
