Milwaukee Impact Wrench Repair

This is a repair of a Milwaukee Impact Wrench M18FHIWP12 with 3 flashes when trigger is pulled and no motor spin
I am an amateur repairer and am completely untrained, I love to try to repair anything i can and some go better than others, I hope to show all parts of a repair to help anyone trying the same,
Don't take my advice as correct because i usually don't know what I'm doing but that's half the fun.
Hope you enjoy and come back for more soon
