Car Purchased from Dealership Fails to Start After Short Period; Suspicious Tracking Unit Discovered Attached to Radiator Fan Wiring

In a recent video, a step-by-step DIY test was presented to measure the parasitic draw from a Progressive Dongle in a car battery. This test can help determine if a car battery dies after sitting for just a day or two is due to a Progressive dongle, OBD2 tracker/monitor dongle, or other hidden dealer-installed GPS units draining power around the clock.

Before you start, ensure you have the necessary tools: a digital multimeter, a small wrench, a short jumper wire, a fuse puller, and a notepad or phone to record readings. It's also crucial to have a fully charged or healthy battery, and the hood should be opened and blocked. Leave the car idle for 30-45 minutes so all modules go to sleep.

To begin the test, unplug the Progressive Dongle. Connect the multimeter in series with the negative battery post and the battery cable, and record the steady mA reading as the baseline. After plugging the Progressive Dongle back in, wait for the car to go back to sleep, and record another steady mA reading. The difference between the two readings is the Dongle's added draw.

Safety precautions are essential during this test. Never start the car or turn on high-current loads while the meter is in amps mode. Work on the negative battery cable for safety, and keep doors closed and dome lights off.

Many mechanics recommend unplugging the Progressive's Dongle, GPS trackers, and unnecessary OBD2 devices, especially in used cars where hidden trackers may already exist. This practice can help maintain the health of your car battery and ensure peace of mind.

Unfortunately, the article does not provide specific information about insurance companies installing GPS devices in the OBD2 port of cars as part of the sale process or financial security measures. Similarly, no information was given about the "COMING UP NEXT" section or the author's background and expertise.

In conclusion, this DIY test provides a practical solution for car owners concerned about their car battery's health and the potential impact of GPS devices. By following the steps outlined, you can determine if a Progressive Dongle or other similar devices are causing unnecessary drain on your car battery.
