Checking Electrical Connections

Terminals in connectors must lock together. Look for connectors that are not fully plugged into each other or terminals that are not fully plugged into insulator. Also make sure the wiring between each connector, and where it goes into the convolute of the harness, is not pinched behind any screws, bolts or rubbing on metal, which would result in a short to ground
