The unit would not run at all. When I looked into the gearbox I found where all the old grease had dried up and turned into something like parafin! So I spent about an hour digging this stuff out. I then applied a little oil and then power and got the unit to turn, roughly but it turned. Both in forward and reverse. Good I thought, more cleaning and we should be getting better. I spent more time cleaning the direction relay, gears, etc. Okay I apply power and all I get is the direction relay to operate, the motor will not turn. Well I start looking around and cannot find anything obvious that would be preventing the unit from running. I checked all wiring to see if something has come loose, wiggled the wires when powered up to see if any connection was poor but all seemed fine. I put an ohmeter across the coil on top of the frame (field??) and have continuity. I just don't know what happened here. There was a lot of sparking at the brushes when the unit was operating and it ran a lot slower in reverse but I'm stumped at the moment...
