I have no electrical background so please excuse my terminology, etc. I have three starters that I am rebuilding and have two with damaged armatures. The one on the left (top far left) has a half inch of exposed wire that goes across the armature. The one at the right has several exposed wires. The left armature seems to use some king of varnish material to keep the wires isolated, the right one seems to have a rubber encasing all the crossing wires. I checked all the exposed wires with a volt meter and non seem to be grounding onto the wide silver bands. I assumed I could epoxy over, or varnish over the exposed wires and that should fix the armatures?

I also have the cloth wrap on a field that is frayed and is unwrapping. I thought this could be easily fixed by also using some varnish to reseal the cloth to the field. Is this okay?

Lastly is their anything else that I should be looking carefully at? I have read through the manual and lacking the instruments to do tests will test the starters on an old engine I have mounted on the front of a sawed off car frame. Thanks, Mike
