DRB III Does Not Power Up
If the LEDs do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage (data link
connector cavity 16). A minimum of 11 volts is required to adequately power the DRB III. Check for proper ground connection at DLC cavities 4 and 5.
If all connections are proper between the DRB III and the vehicle or other devices, and the vehicle battery is fully charged, and inoperative DRB III may
be the result of faulty cable or vehicle wiring.
