5. Setup

5.1 MP0515A 12V Car Battery Load Tester Setup

1. Ensure the vehicle's ignition is off and all accessories are turned off.
2. Connect the red positive (+) clamp of the tester to the positive (+) terminal of the 12V vehicle battery.
3. Connect the black negative (-) clamp of the tester to the negative (-) terminal of the 12V vehicle battery.
4. Ensure both connections are secure and free from corrosion. The tester will power on automatically.

5.2 MP69040 OBD2 Scanner Setup

1. Locate the vehicle's 16-pin Data Link Connector (DLC), typically found under the dashboard on the driver's side.
2. Plug the MP69040's OBD2 cable firmly into the vehicle's DLC.
3. Turn the vehicle's ignition to the 'ON' position (engine off or running, depending on the test). The scanner will power on automatically.

6. Operating Instructions

6.1.1 Battery Status Test (Vehicle Off)

1. Ensure the MP0515A is correctly connected to the 12V battery with the vehicle's engine off.
2. Observe the digital voltage display.
3. Read the battery status indicated by the LEDs on the left side of the tester:
   • FULL: Battery is fully charged.
   • MEDIUM: Battery has a moderate charge.
   • LOW: Battery charge is low, consider charging.
   • EMPTY: Battery is discharged or critically low.

6.1.2 Alternator / Charging System Test (Vehicle Running)

1. Ensure the MP0515A is correctly connected to the 12V battery.
2. Start the vehicle's engine and let it run at idle.
3. Observe the digital voltage display. A healthy charging system typically shows around 13.5V to 14.5V.
4. Read the alternator status indicated by the LEDs on the right side of the tester:
   • HIGH: Alternator output voltage is too high.
   • GOOD: Alternator output is within normal operating range.
   • DEAD: Alternator is not charging the battery.
   • REVERSE: Indicates incorrect polarity connection (clamps reversed).

8. Troubleshooting

8.1 MP0515A Battery Tester Troubleshooting

• Display shows "LO": The battery voltage is under 4V DC. The battery may be severely discharged or faulty.
• Display shows "HI": The battery voltage is above 20V DC. This is outside the normal operating range for a 12V system and may indicate a charging system fault or incorrect application.
• "REVERSE" LED is lit: The positive and negative clamps are connected to the wrong battery terminals. Disconnect immediately and reconnect with correct polarity.
• No display/No power: Ensure clamps are securely connected to the battery terminals and the battery has sufficient voltage (above 4V).

8.2 MP69040 OBD2 Scanner Troubleshooting

• Scanner does not power on: Check that the OBD2 cable is securely connected to the vehicle's DLC and the vehicle's ignition is in the 'ON' position. Verify the vehicle's battery is not dead.
• "Link Error" or "Communication Error": Ensure the OBD2 cable is properly connected. Verify the vehicle is OBDII/EOBD compliant and not a new energy or hybrid vehicle. Try turning the ignition off and on again, or try on a different compatible vehicle if available.
• Screen frozen/unresponsive: Disconnect the scanner from the vehicle, wait a few seconds, and reconnect.
