How do I hook up 5 hp motor

Hi guys a friend of my husbands gave me an old 5 horse electric motor single
phase 220 volts. It has no wiring diagram with it. there are 4 wires
(black) in a metal box mounted on the side of the motor. Two of the black
wires have an extra band of tape on them. If I take an meter to one of the
banded wires and one of the not banded wires I get a short and the same
thing with the other two. So would I take both banded wires to one side of
the 220 and the other two not banded wires to the other side of the 220 or
do they go in series
I don't want to burn it out before I get to use it
Thanks Guys

Take it to a qualified motor shop or a scrap dealer.

There is no way anyone here is going to tell you any combination of
hooking up a bunch of unknown black wires with "an extra band of tape on
them" and connect it to mains of any kind.

Even if you were able to discern the actual resistance of a winding - it's
not a short, just typically less than one ohm - you have no way of
checking their phasing. Two of them are probably the capacitor connection,
but there's no way to tell.

Do not under any circumstances connect that motor to any kind of mains
power until it has physically been gone over by a qualified motor
technician and deemed safe. And, the tech needs to be qualified to
determine the proper phasing and capacitance of the start/run cap.

Sorry.

Totally agree!! Seen too many breakers, and caps damaged by someone
experimenting with these connections, guessing at the appropriate hookups.
