NOTE: When troubleshooting an electrical system, make sure there are no electrical loads ON, except for the circuits or system being tested. This will help prevent false readings and the chance of a dead battery. After the car has been serviced, always visually inspect the battery to be sure the Green Eye is visible in the battery hydrometer.
