Got a 3 stop in ground dover freight car. No prints on site, had an issue prior to us taking it over with the valve, we are installing a new valve, tank and motor, and starter. Troubleshooting now as it won’t run … data tag on controller says tested in 1966. Also says wiring diagram DW - 8794
Wondering if anyone has a set of those or something similar? Or has any knowledge of this vintage equipment?
