its usually such a thin layer in plating on those plugs that it oxidizes or tarnishes. if you ever run across de-oxit it works great for cleaning up connections, its kinda pricey but it only takes a tiny bit
Well back to the gold never oxidizes; a thick layer isn't needed, I have gold connections for over 20 years that are like the day I bought them because they have any amount of gold covering them, so long as they are covered.
It appears that you think gold never oxidizes unless it's thin; gold doesn't oxidize no matter how thin it is. It simply doesn't oxidize period. Perhaps you're thinking about so other costume jewelry with a fake coating or something but gold DOES NOT OXIDIZE, PERIOD.
Believe what you want but please dont mislead the people here, these are good quality, gold plated connectors. And they're not cheap.
And a word of caution to those who might choose to try and save a couple of bucks; the plugs of Stoker attachments are mini computers in themselves. There's a good chance, if you aren't sure what you're doing (meaning how that plug interacts with the computers) that you will blow, at 30.00 per plug, all your plugs to save how much?
So please take if from someone who has experience with and understands the Stoker equipment and take my suggestion. It could save you hundreds of dollars worth of probes. So often when someone comes up with sound advice with experience behind it, someone else feels that without knowing anything about what they are really talking about has a better idea and tries to discredit the one who knows. More and more I find this true on this board; you need to me vary mindful of who you take advice from. It could hurt you in the end.
