921.153640 motor runs then sparks fly
by Dennis Keeler
Craftsman air compressor model 921.153640,1hp,7gal, little or no use since new.
921.153640 motor runs then sparks fly behind the fan then circuit trips.
Started the unit today and engine would try to turn, did this over and over then finally kicked and ran filling the tank to capacity. I repeated this a few times then it sparked in front of the fan and tripped the circuit.
Attempting to start again and we are back to not turning over, wants to but will not. I notice a yellow circuit board where sparking occurred, it looks like there are points, it looks a bit black and sooty in that area. Any thoughts. Thanks Den
wiring motor and switches
Rewiring my Craftsman
Took my compressor apart to fix it, now I don't know where the wires go from the brushes, motor, pressure and shut off switches.
The ground wire is the only thing attached from the plug coming in, because it is not a spade connector.
