Would someone please tell me how to wire a 6 volt am gauge in a 1953 jubilee tractor. The am gauge I now have has a connection for Lights and Battery.

Tractor or old vehicle Ammeters aren't typically rated "6 Volt or "12 Volt, they will work on either voltage.
What's important is that they are rated for enough Amps to handle the charging system output (and expected load on the battery).
You say your Ammeter is marked "Lights" and "Battery"?
I've never seen that??? Could be "B"attery and "L"oad?
ANYHOW, the power wire from the battery goes to one Ammeter terminal post and the output of the charging system and ALL electrical loads go to the other terminal post.
If the Ammeter reads backwards, swap the wiring leads between the two posts.
The yellow wire coming from the battery NEG (connection at solenoid) will connect to POSITIVE terminal of your new ammeter and the yellow to terminal block will connect to NEGATIVE terminal of ammeter. The light wire will connect to headlight switch if you have lights and if not then connect to opposite side of terminal block.

Disconnect the battery. Take all your wires off all the old ammeter or one side should have just one wire. Disconnect your battery and unhook that wire. Make sure it will not touch metal and reconnect the battery. Test the single wire and make sure that wire has power. If so disconnect the battery and all the wires from the old ammeter. Now connect the single wire to the plus terminal of the new ammeter all other load or charging wires to the ammeter will go to the negative terminal of the ammeter.

I like to describe the two terminals on an ammeter as SUPPLY and LOAD. If one is marked BATTERY I would take that to be its SUPPLY with the other side as LOAD and its feeds voltage to loads like lights and ignition..
Try wiring the ammeters BATTERY to the battery, perhaps where the big battery cable attaches to the INPUT side of a starter switch or solenoid,,,,,,,, and other wires such as the Genny/Voltage Regulator (BAT on a Voltage Regulator) as well as the input to any light switches or ignition on the other LOAD side. If it reads backwards simply reverse the leads side to side.
Often theres ONLY ONE wire on the SUPPLY side IE the one that gets to battery with maybe TWO WIRES on the LOAD side, one to BAT terminal on a Voltage Regulator or Cutout relay and one to light and ignition switches.
Best guess on your ammeter BATT is the SUPPLY side and LIGHTS is the LOAD side. Wire BATT to battery and LIGHTS to light and/or ignition switches PLUS the output of the charging system (typical BAT on the VR) wires there also

Follow the wiring diagram. Battery voltage is picked up at the supply side of starting solenoid, goes to the ammeter, then comes out the other side of the ammeter and goes to the terminal block for further distribution. If you get the wires backwards on the ammeter it will simply read backwards, switch the wires around.

The diagram came from Ford Service Manual
40060090 which covers 4 Cylinder tractors
from 1954 - 1964.
