So my grandpas air compressor quit working and he thought it was the on/off switch and tried replacing it but I'm guessing wired it up wrong and fried the mother board. I called snap on and they no longer make that part anymore and after talking with a guy from sleegers they advised that I have a magnetic motor starter installed. I'm wanting to fix it for him for Christmas so any advice on what magnetic starter I should go with would be greatly appreciated!!! The compressor is a Snap-on model AC580v, 80 gallon vertical tank. 5HP two-stage pump, motor is a 184T frame 5hp marathon electric-1745 RPM wired for 240v single phase operation.
