1. unplug all devices from your vehicle and make sure no electrical components are on. turn off the radio, heat or a c, lights, windshield wipers, etc. and close your glovebox and lighted mirror covers. engage the emergency brake, turn your vehicle off, and remove the key from the ignition if you haven't already. In order to accurately detect the parasitic draw, you need to begin with a fully charged battery. pop the hood and locate your vehicle's battery. pop the hood and locate your vehicle's battery. use a vehicle battery charger to charge the battery to 100%.

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. Use a multimeter and these step by step instructions to perform voltage drop tests to isolate is something draining your car's battery? don't pay a mechanic! use a multimeter and these step by. Step 3: remove and replace fuses. start with your underhood fuse panel. make sure that you can see your multimeter while you pull fuses. use your needle nose pliers or a fuse puller to remove and replace fuses, until you see the amps on the multimeter drop. be careful that each fuse goes back into the correct location. To find parasitic battery drain, check the battery’s voltage across its terminals, disconnect the negative cable, then check the current after removing each fuse. the voltage of a fully charged battery with the engine off should be within the range of 12.6 12.8 volts; otherwise, it should have at least 12.4 12.6 volts to crank the engine.

Parasitic battery drain testing for current draw using a multimeter and amp clamp • leave battery terminals connected to the battery. • connect the low current amp clamp to the negative battery cable. • with the key out of the ignition, let the vehicle sit for 15 45 mins to allow time for all computers to enter “sleep” mode. Follow the steps below carefully to find and fix a parasitic battery drain: 1. disconnect every device from your car. the first step is to disconnect electronic devices from your car, including a c or heat, turning off the radio, windshield wiper, and lights, to mention a few. next, do the following:.
