On both of my vehicles, the cable from the Positive terminal of the battery goes to the input [always "hot"] terminal of a solenoid mounted on the right front inner fender. A similar heavy cable goes from the solenoid output [ignition switch controlled] terminal to the starter.
There are also lighter conductors that go from the hot input terminal of the solenoid to the vehicle's electrical system.
From battery to starter solenoid
The positive battery terminal goes to ground, the negative terminal goes to the starter solenoid.
Find the positive battery terminal. Follow the thick cable from that terminal and it will lead to the starter solenoid.
The positive connector on a lead acid battery is frequently not white. In the United States, the wire that leads to it is usually red. The black wire leads to the negative terminal. The positive terminal on the battery is always indicated by a plus, +, sign. The Negative terminal is indicated by a minus, -, sign. The negative terminal is usually attached to the body of the car. (Cars have a negative ground, except for 1935-1948 Fords.) The positive connector is usually attached to the solenoid and generator. So check the wire that comes from the battery to the solenoid. That is positive. Check to make sure it is connected +.

The negative terminal of a battery has a - sign and positive terminal has a + sign.
The positive end of a battery goes to the positive end of the terminal. In retro spec, the negative end of a battery goes to the negative end of the terminal.
The positive + terminal is slightly larger.
the positive terminal in a battery
Two. The positive terminal, and the negative.
The battery in located in the trunk, and the positive terminal is the one that is slightly larger and labeled with a + sign.
Mostly fusible link for starter solenoid is located very close to the battery or between the battery fuse and terminal.
