Where is the negative terminal of the Volvo S90 battery?
1 Answers
The positive terminal of the battery will be covered with a red cap, and opening the cap will reveal a terminal with a fuse, indicating the positive terminal. If the battery cables are connected in the car, the positive terminal will have more wires and fuses, while the negative terminal is grounded with only one wire. The battery will clearly be marked with '+' and '-' signs. More maintenance information is as follows: 1. Open the battery water filler cap and check if the water level is at the normal position: There are usually upper and lower limit marks on the side of the battery for reference. If the water level is below the lower mark, distilled water must be added. If distilled water is not immediately available, filtered tap water can be used as an emergency measure. Do not add too much water; the standard is to fill it to the middle between the upper and lower marks. 2. Check if the battery is charging properly: If you have a multimeter, measure the voltage across the battery terminals after starting the engine. It must exceed 13V to be considered normal. If the charging voltage is too low, a professional should inspect the charging system. If you don't have a multimeter, you can use a visual method: After starting the engine, open the battery water filler cap and check if there are bubbles in each cell.
