I have a clark super 7r edger. I had the armature turned and replaced all berings. after putting back together, even consulting the wiring diagram the armature runs in reverse. How to correct? anyone it has 4 brushes

On each end of the starter armature are oil lite bearings as the bearings wear it allows the armature to drag against the coil assembly of the starter causing it to rotate slowly. In this case it should be drawing much current. More than the draw when it is free. The bearings can be replaced and it is typically the one on the starter gear end of the armature. The other end does not wear as much as it does not see the load that the starter gear is on. I typically just grease the back end and leave the bearing alone.
While you have it apart it is smart to replace the brushes too.

seems to be issues with wires not seated properly, I had a wire that was not seated in the trigger switch. reinserted wire. Be careful on putting the wires back in place, not a lot of play. If not the switch, check the wires at the armature.

This will help, I thinkhttp://www.carlsalter.com/download.asp?p=1008
If not, feel free to ask again any clarifications you may need.

I have a black & Decker Electric Edge Hog, does not turn on anymore. Is there a fuse or power reset switch?

That sounds right but let me do a little extra research for you. and I will let you know later today.

The rubber backup plate threads on. You can make up a bracket to insert into the 2 larger holes of the plate. You must keep the fan of the edger from turning to unscrew the plate. I use a hard piece of wood or if you are careful, a large screw driver. The plate unscrews counter-clockwise.

turn trimmer upside down grab the spool head firmly and pull out replace string but wind in the way arrow shows you and replace fishing the loose end back through the hole on the side as you slip back together ,once together grab string and pull to remove any slack and away you go

Well it turned out that that 45 degree plastic piece DID or WAS attached to the main post. It snapped off. I super glued it back on and to each side of that very flimzy broken plastic I cut two very small pieces of wood (using popsicle sticks) and super glued THOSE to either side of the broken armature piece. Once dried I re-attached the spring and it worksd like a charm.
