    You're not giving us much to go on here.

    Is this a "condensing unit" with a compressor, receiver, etc. or is it an "air-cooled condenser" with just a coil and fan(s)? There's a big difference.

    Pictures would help, but I think you need a few more posts before you can post pics.

    It's a whole condenser. Compressor, receiver, contactor, defrost control , I'd say it's probably 20-25 years old

    Then in proper Refrigeration terminology, that would be a "condensing unit".

    The only Hussmann condensing units with vertical air discharge that I recall would be in the 10+ horsepower range and up. Essentially, those are skids with a compressor package mounted at the header end of the condenser.

    For starters, what is the compressor model number? That would help narrow this down a bit. Also, what's the application and refrigerant? HT, MT or LT?

    If it's 20-25 years old, I could have info on it. That's my era.

    This may help:

    The typical electrical schematics near the end are fairly generic, so whatever it is you're looking for should be in there someplace.
