The next steps to follow after you checked the power source & brushes.

I recently received a Dewalt DW718 that was giving to me by a buddy because it didn’t work. I already have changed the brushes (nothing) and armature only because it was given to me. I need a little advise as far as what steps or what should I go about doing next. I really would like to get it going because I could put it to good use or sell it & try to make a little profit off of it. What do y’all think?

Did you go over the cord ? Test the cord from end to end. I’ve seen where there wasn’t a physical cut or anything but it was on the inside and the wire just pulled out. Next check the switch . If there is a way to bypass it do that so its directly hooked up. Test the switch to see if it works when the trigger is squeezed. Also make sure the brushes are making good contact.
