If you are asking me, the acc. turned on the servo transformer.I gutted out all of the electronics. I am using the acc. contactor to turn on the servo transformer wich powers my gecko 320x's . I also will use it to power the
PMDX 126.on 220 volts. I am powering the relay from 110 volts at the control panel. When I power the relay, the gecko drive and the bob powers up. Hope this helps you. The acc & the forward spindle relay had a 3UA Thermal delay
relay on it. I took that off to get the relays to work. Don't know what they were for. Dave
