"looks good" and "is good" are not interchangeable, you need to measure voltage.

Seems a lot of people forget, Electric grease is non conductive it's not going to fix anything it's a protective coating prevents oxidation and arcing. You scrubbed those connectors to bright shiny metal?

Second that^^^!
Even a wire that reads low on resistance may be too corroded/ too thin to carry the current. Measuring voltage bet one end of that suspect wire and the other end under load would reveal this.

O.P., Pls see my post on how to check a fuse. Same would apply to checking a suspect wire.
