I just acquired an SA-2500 Antenna tuner. It was represented as non working, for parts or repair. They showed a picture of the connections that were not connected. When I opened it up I found that the inductor motor was disconnected as stated. I measured the motor winding and it seems normal at about 35 ohms so its not burned out or shorted. Everything seems to work....except the inductor up/down switch. The inductor is NOT jambed and appears to move easily. I have NOT re connected the inductor motor and wont until I have some idea why it was disconnected. All the lights on the front pannel light as they should when the switches are operated. I have not yet connected it to a transmitter. Question 1: Could someone have disconnected the inductor tuning in order to use it as a single band tuner? Question 2 : Any suggestions for further trouble shooting before I reconnect the motor and a transmitter and see if it works?
