    On our MO both the resettable counter and totalizer seem to have gone bad. Seems odd that they would both go at the same time. When I took the counter out it seems they operate independently making me think that the 24v is the problem. Could someone tell me where the 24v is coming from?

    Hi sir:
    1) Please your schematic diagram, the +24Vdc is coming from Rectifier N1.
    2) However if you do not have: measure the Fuses:e5+e14, for 4 Amps.,after secondary of main transformer m6.
    3) Look for loose wires, or corroded,: a) tight very well b) clean it with special contacts cleaner spray.
