Two technicians are diagnosing a failed horn circuit. Technician A states that connecting a fused jumper lead from terminal 86 to terminal 85 in the relay box should sound the horn. Technician B states that resistance between pin 85 and 86 on the relay should be 40 - 100 ohms. Which technician is correct?
