2. If ohmmeter shows continuity with no resistance, check connector for poor contact. If contact is good, replace computer.
3. If ohmmeter does not show continuity, repair wire for open circuit.
4. If ohmmeter shows continuity with resistance, check for pinched or poorly connected wire and repair as necessary.
