How do you know which terminal on a starter is positive and one ground?

To determine which terminal on a starter is positive and which one is ground, you can refer to the starter's wiring diagram or technical specifications. However, here are some general guidelines to help you identify them:

1. Positive Terminal (Power):

- The positive terminal is typically labeled with a "+" symbol.

- It is the terminal where the battery's positive cable is connected.

- It receives electrical power from the battery.

2. Ground Terminal (Negative):

- The ground terminal is usually labeled with a "-" symbol.

- It is the terminal where the starter's ground cable or ground strap is connected.

- It provides the electrical circuit's grounding point.

Remember that these guidelines are general and may vary depending on the specific starter model and manufacturer's design. If you're unsure about the terminal connections, consult the starter's documentation or seek assistance from a qualified mechanic or electrician.
