Take the new cables and strip the insulation from the ends, just like you did with the old cables. Then, attach the cables to the terminals, making sure they’re securely seated and tightened.
Step 5: Reconnect the Positive Cable
Take the positive cable and attach it to the positive terminal on the battery. Make sure it’s securely seated and tightened.
Step 6: Reconnect the Negative Cable
Take the negative cable and attach it to the negative terminal on the battery. Make sure it’s securely seated and tightened.
Step 7: Check the Cables and Terminals
Double-check that all cables and terminals are securely attached and tightened. Use your terminal cleaner and protector to clean and protect the terminals, and make sure the cables are not damaged or frayed. (See Also: Does Heat Drain Car Battery? The Surprising Truth)
