Thank you guys; Mike I understand the word “isolation” so it sounds like something I’m looking for if I go directly from my 12 v batter. I didn’t see any connectors on it. Does it have 3 or 4 connectors? If it has 3, I would assume it has a “+in”, “+out” and a common ground. If it has 4 then I would assume it has “+in”, “+out” and 2 individual grounds. The 4 wire, I could understand working without a common ground.
Good point JO; I knew when I used the saw that I could be looking for trouble. When it happened, I’m not sure, but I thought to myself, I rolled the dice and lost and put it in the corner. I’m on my way to the shop now, and I will check the overload switch-- there must be one.
PS JO; You asked if we had vehicle inspections— no. It would take a large portion of the vehicles off the road, from rust.
Thanks for the replies TomC
