I bought an old Snap On MT 1590 AVR battery tester over the weekend. Guy was asking $75, but when I got there he couldn't find the power chord. He was going to give it to me, but I gave him $25. No manual & I'm trying to figure out what spec power supply I need. Does anyone have one or a manual that you could let me know? Can't find any manual on line yet & Snap On doesn't list it on their site.
