Why do all the lights stay on and the Motorvac 500-1125B unit gives a steady tone when connected to a battery?

This issue could stem from several factors: * Verify that the battery voltage is at a good level (12.5 volts) and properly connected. * Note that the unit isn't designed to operate using a booster pack. * Try connecting the unit to a new, fully charged battery. * Inspect the wiring for any signs of damage.
