TIL the hard way that old harness repair trick from a guy in Wichita was garbage
Last year at a regional airport in Wichita, this old tech told me to use dielectric grease on all the cannon plug contacts during repair. I tried it on a 737-300 aft equipment bay harness, and six weeks later the pins started corroding anyway. Took me two full weekends to redo that whole harness because the grease trapped moisture instead of keeping it out. Anyone else get burned by bad advice from a 'seasoned' tech?
