Motor Vehicle Maintenance & Repair Asked on March 31, 2021
I have just cleaned ignition switch internals with sand paper. When doing so the silver plates got scratched up and some areas the underlying(copper?) got revealed.
You can also see there are stubborn black marks, especially on the wired side of the plate(don’t know what these marks are) and they just didn’t come off.
Is this result ok or are the concerns above going to create problems and are those black marks of some underlying damage and the switch May still be faulty?
With out plating the copper is a much softer metal. It will wear a lot quicker then it is suppose to and will need replacing.
I guess in theory, Once the contacts start getting thin then there could be problems with them getting too hot, maybe even melting the housing a little. I reckon the starter circuit would be the most worrisome.
