I recently purchased a Syncrowave 250 unit only, but I got a good deal on it. I tested it on scratch start and it worked fine. When I hook up the pedal, I have no remote amperage control. The machine runs at whatever amperage I have set on the dial. Local/ remote switch checks ok. What ohm readings should I get on the foot pedal? It's the RFCS-5 one. Machine serial is JJ385060. I have the owners manual and technical manual.
