Single terminal motor question....
Hello,
I am designing and building a heating system for a classic vehicle. I purchased a single terminal motor to use for the heater blower fan. My question is: since there is only one terminal on the motor I am assuming that it is "positive" and that running a wire from the metal motor platform to the chassis/frame will complete the circuit.
Hopefully, someone who has experience with these motors can confirm or correct my assumption.
Thank you for your help.

Welcome to the forums.
Your assumption is correct.
The metal shell of the motor is negative and the connection post is your positive connection.

A lot of auto electric things (motors, ignitions systems etc)are built that way, The medal is ground, newer cars with computers sometimes have ground wires.

Except that, depending on what you have, you need to confirm that your vehicle has a negative ground, rather than positive ground.

If the motor you purchased was originally designed for a + ground vehicle then your assumption would be wrong.
Hook it up to a battery and see if it rotates in the direction that you want. Question would then be answered.
