Here’s a few pics of the inside of a timing relay. When mine started acting up the very small wires at the base of the one arm broke, or burnt off .
Thanks again Welder guy - I have the same problem. I wouldn't have known there was even a bulb in there without this post. The ignition is kinda strange on the 69 models - being on the left and so low down, it's hard to find at night or at any time of day in underground carparks. I understand the concept was to improve security (such as to establish some distance from kids in the front seats who might fool around), but it is a little counter-intuitive for many drivers...Your bulb is inside that small silver tube with the hole in it held in place by that screw in your second picture , it could be burnt out or the time delay relay is bad here is a great thread on the topic 1970 Fury Time Delay Relay
