Quoted from PinbotForBob:I'd appreciate anyone's input, on whether or not using a tiny amount of dielectric grease on ribbon cables and other connection points is at all recommended.
No, makes a mess. Some people use tweak or other contact enhancer, but really, replace the connector like ForceFlow says. It's just worn out.
We use dielectric grease at my job for connectors that are exposed to road salt and other chemical hazards, as well as temperature extremes, and it's a higher current than the ribbon cables are.
I did mess around with using it on stubborn bulb sockets. While it did 'work' - it was REALLY messy when you went to change a bulb. Never again.
FWIW, the people that weren't used to it at work when they pulled the module out, they weren't too happy about the greasiness on their fingers, either.... so I asked them why they were holding the module at that point. It was literally a 1/2" portion of about 1 foot wide, and not in the middle either.
