Just towed my 2018 1.5 liter two wheel drive Equinox for my first all day drive. Using magnetic LED light bar plugged into rear12v outlet. Mid day check, started for 5 min., all seemed ok. At end of day, completely dead. Do not have battery maintainer installed, thought the LEDs wouldn’t draw enough to faze it in daytime driving. Guess I was wrong.
Not responding to charger, at a loss. Stuck.
