Hello everyone this is me Yuriy a guy from Venezuela, and to be honest my English is not that good but ill try to explain in a good way, the situation is that... here in Venezuela, doesn't exist the ground connection at all.. is like the electricity companies doesn't provide that connection to our houses or apartments which is kinda annoying, but is funny because when you go to a mall to buy some Outlets, they came with a plastic connection for the ground-pin hahah, and when you put that metal or plastic outlet in our walls,... is kinda funny because people when connects those Ground Pin from Devices, the ground pin keeps like in the air... Anyway, my question is, does a old cables from a building, with more than 20-30 years,plus no ground connection, can cause Dirty Electricity? like... degrading device performance? or burning things like Bulbs, electric protectors, cables, etc? Im asking because, in my family apartment it seems that, Electric protectors do not last long... like their plastic from regulators become like brown, like burn, of course it still working but... the smell is not that good... also the Light Bulbs does not last long too.. like 5 months or 7 months And another thing is that i'm pretty sure that a bad electricity or dirty electricity can affect devices a modem which provide internet services, right? Or affect my Gaming computer, there are many forums where the people says/claim that their performance in gaming is terrible, they have build everything from scratch, a good pair of memory ram, good power supply, good motherboard that match CPU, and VIDEO CARD, but their performance is like not good, even at good fps... they say they feel like visual lag, mouse lag, some of them claims that, when they put the Ground Connection, the computer experience improves, also some of them bought too a UPS which converts AC TO DC, and AC To DC double conversion, and the experience is insane, so at the of the day, all points to Electricity, and yeah i was wondering if that is true? Becuase i use to play in a house.... and the experience was better, now that im living in and old building, in a second floor.... an appartament, i can telll that, the visual lag is terrible, no matter what i do... problem persist, and im not crazy :(. Hope someone can guidance me, if there anything i can do? meanwhile.. because here in Venezuela situation is difficult

Hi out there to people who fix stuff. I have an old Wayne upright air compressor with 80 gallon upright with a 5hp Dayton motor connected to another 80 gallon tank . The setup has a Square D magnetic starter wired up with 220 and 120 to the coil I believe. I use the compressor at home to do autobody repair work. I have not really had any issues with the compressor for some time besides my needing to rebuild the pump slow pumping. Anyway's I am now encountering sticking contacts in the magnetic starter then the valve will blow off and I have to turn off the compressor , open the starter box and pull the contacts apart. What can I do to properly clean or resolve this sticking contact issue? I thank you for you're help. I have folded small thin piece of 180 grit and pulled sand paper back and forth trying to clean the contacts I do not think it's very helpful.
