I just remembered something! When Dad was still with C&NW back in the 80's, they had a bunch of F-Series highrails they were leasing that were refusing to start when on or near the tracks on hot summer days. It was driving them nuts because it put the track and train crews in danger in those situations and the Ford shops (as well as the company) kept insisting there wasn't anything wrong with the trucks showing these symptoms. Turns out the ignition modules for those trucks were mounted to the left front inner fenderwell right by the exhaust manifold for the engines left bank. At one point a couple track workers radioed in that their truck wouldn't start and a train was coming along on the same track they were currently sitting on. Dad happened to be there to hear it and asked if they had any water available, and they had one of those big Igloo dispensers in the bed. Dad told them to dump that on the ignition module and see if that would work. They thought he was crazy, but since there were no other options, did it anyway and he truck fired up and they were able to get it to either the next siding or road crossing and get it off the that track. That's when they officially figured out those modules were getting heat soaked and refusing to work and told Ford what they found as well as a suggestion to fix it. Ford told them they didn't know what they were talking about and that if they went through with the fix they had planned, which was to extend the harness and move the module up by the left front headlight where it would see cooler temps, the warranties would be voided on all such modified trucks. The road went for employee safety instead and made the changes anyway, then when it came time to lease new track vehicles, made the switch to GMC from then on until the UP gobbled them up.
