need help fixing Bodine SCR FPM-850 (0850) AC to DC mtr speed control
(OP)
I have a good one and a broken one. The attached motor shorted and broke the 0850. I have a dvm. Neither fuse in the FPM blew, but the shop 20a breaker tripped. Two parallel 0.33 ohm resisters were opened, so I replaced them, but that did not fix it. I have looked high and low and cant find a schematic. Bodine is absolutely No help.

If everything in order, disconnect load and put a load bank intead. Use incandescent lamps in series and parallel to have a load that represents at least one or twp percent of the rated load.
Check out function of gating unit. There is usually a removable link between current controller and gating unit, remove it and put a control voltage +/-10 V on the gating unit's input. Vary control voltage and see if lamps go from dark to bright. If they do, your gating is probably OK. If you see any flicker in the light, one gating pulse or one thyristor may be faulty.
This is getting a littke bit boring. And you still havent checked current controller and speed controller. There must be someone around that can help you. I could pop in and do it, but Sweden is a bit far away.

I attach what I can find for that device. It is the installation manual and it contains a section on fault-finding. Next step is to buy a new unit.
