    I was given a mfj-269 but it won't power up with batteries or an external source I have the schematic but seem to be having a hard time finding where power comes in on the schematic.
    Any insights would be great.

    I found it on page 2. Will see if power goes past switch.

    Mine did the same thing. Found there was a jumper (old style computer type, Suitcase type) that was corroded. Puled it, cleaned the pins, put a new one in. Now works fine.
