If you’re having trouble finding the battery, check your manual to see where it is.

The next step is to determine which terminal is positive and which terminal is negative. The positive terminal will typically display a “+” sign, while the negative terminal will typically display a “–” sign. You should double-check your manual in the event that the cable color on the positive is different from the cable color on the negative.

With the negative connector, try to avoid touching any other metal parts on the vehicle. When you reconnect the negative terminal, you may experience a slight spark, but this should not be dangerous.
