How to Check the 12V Battery's Charge

Knowing the voltage of the battery is the best way to determine the state of charge.

Before you begin, gather the following:

• Safety gear as required by your job site
• Multimeter

To check the 12V battery charge:

1. Make sure the tractor is in Neutral with the parking brake on.
2. Open the top cover and remove the tool tray to access the battery.
3. Get ready your multimeter (read instructions for your multimeter for information).
4. Place the red probe on the positive (+) terminal of the 12V battery.
5. Place the black probe on the negative (-) terminal of the 12V battery.
   
   
   A. 12V battery
   B. Negative (-) terminal
   C. Main switch in ON position
   D. Positive (+) terminal
   E. Ground lug
6. Read the multimeter. Note the following:

• • You should see a reading above 10V; ideally between 11V and 13V.​
  • A declining voltage reading (going from 10V to 9V) suggests a draining battery.
  • If a battery reaches 0, the circuitry in the battery is like the issue. Replace the battery.
