Joe, sometimes it's those jobs that your helper learns the most from :D
One of my favorite moments as my dad's handyman's helper: "Umm...Dad, is the little motor gizmo supposed to be smoking like...hey, we got sparks...OH CRAP! IT'S ON FIRE! Why don't you have a fire extinguisher like a normal person??!!" We were working on the plow motor on my brother's truck. We ended up going to Brownie's Auto Parts and ordering a new one.
