How to find out if a battery is parasitic?
Connect the black wire to the “com” (common ground) input and plug the red wire into the highest amp input (usually 20A). Set the dial on the multimeter to measure amps. Choose a digital meter than can read up to 20 amps and down to 200 milliamps.
How can I find out if my car has a parasitic draw?
Luckily, you can usually find the cause of a parasitic draw yourself. Start by connecting a digital multimeter to the negative battery terminal of your vehicle. Then, remove the fuses one at a time while watching for changes in the multimeter’s reading. Once the reading drops, you’ve found the culprit and can take steps to repair it.
Do you need a multimeter to check battery draw?
To troubleshoot the current draw, you need a multimeter that can perform current reading. The multimeter should be able to read at least a 10 amp current. Multimeters are very inexpensive and be purchased for under $20.
