The second guess would be the start capacitor on the motor, but from the way you "didn't" describe this, I'm guessing it's not the problem. When you push the start button, do you hear the motor humming, as though it is trying to start? If you hear the hum, then it's the capacitor. Easy replacement. Additionally, if it is the capacitor, shut the motor off immediately when it doesn't start, because the amperage through the motor gets very high.
No , it doesnt hum, it just sort of "bumps", moves an inch or 2, and shuts off. Then sometimes it starts totally normally. This saw has been sitting for who knows how long, not powered up, at my Son in Laws place of work. He spotted it, knew i was looking for a table saw to replace my piece of crap, and asked if i wanted it. (I will keep him!). I did change the cable coming out of the starter (contactor?) being very careful to match locations exactly. I was looking on line, and saw that i can get a magnetic switch for like 30$, and am wondering if I should give that a shot and just replace the one on it now? Im an amateur, my Son in Law is a contractor, and he felt it would be fine as ill never be cutting stacks of plywood on it. This is for my home shop, and as i have always wanted one of these monsters, I want to get it right.
I only joined up yesterday, so I will do the "hello, this is my shop" posting when I get a chance, with some pics, as our power just came back on as well (im in ny).
Thanks so much in advance, let me know what you think about the switch, and ill try to figure out what capacitors I need, as they are a cheap replacement and I have been reading they do fail. (they just scare the crap out of me, as I got zapped by one when I was a kid, and it literally brought me to my knees).
