I tried to start my 70 challenger and had the fusible link burn up. I started doing some ohm testing with the key in run and checked the ignition harness (unhooked at bottom of column) going up the steering column and found ground on the battery and ignition 2 leads of the harness so my guess is the ignition switch. I'm so glad the fusible link did its job or I probably would have roasted marshmallows over the fire.
I seen the other post on replacing it and this job really sounds like it is going to be a royal pain in the you know what. I do have the 70 dart/challenger service manual (really thick yellow book).
I have never tried to take a steering column apart. Anybody with alot of experience doing this job that could help and kind of walk me through this??????
