SWest Electroplating unit damaged - ideas for repair?

The SWest Electroplating unit in our shop was damaged when one of the jewelers put in a 25 Amp fuse, when no more than a 10 Amp fuse is recommended. This particular unit has 2 meters: 0-10 VDC and 0-10 Amp DC. The 0-10 Amp DC meter is wired in series, so I replaced it with a new one. However, we are able to only draw about 1 Amps when we try it (where the unit used to draw upwards of 10 amps DC peak.) So, there must be something else wrong as well. The other 3 components I would guess that would be likely be suspect, and limiting our DC current include:

1) AC voltage rheostat;
2) Transformer 125 volt primary 10 volts at secondary
3) rectifier - getting 10 volts AC where connected to transformer secondary; and, 10 volts DC max out

I have looked all over the internet trying to find a schematic for this unit. So, I'm not sure where to go next. Thank you in advance for any ideas or help you may have.

What you probably need is a rectifier repair serviceperson. S/he will have the instruments and experience to fix this in nothing flat, and will have access to replacement voltmeters, ammeters, shunts, and whatever else you need. Near the top of this page you'll see a link to our search engine. Choose to search the Products & Services Directory with the search term 'rectifier'. You could also try that term in your local yellow pages.
