You wont be reading amps, to read amps there has to be a load and the ammeter has to be in series with the load, you'll be reading AC volts. If you get no ACV between the two wires (RR unplugged) coming from under the flywheel (stator) it means the stator went south, the magnets either went with them or by themselves or the wire itself is bad. 10 chances to one it's the RR tho, so it'd be an easy fix....Mike
