Over time, a connector's housing can crack or turn brittle, and its terminals can corrode or loosen. A melted housing, green or white corrosion on the terminals, or a switch that works only some of the time may be signs this part needs replacing. Diagnose the circuit before you replace anything, because the switch or the wiring can also cause these symptoms. If the original connector is the problem, the S-1605 replaces it.
