Technician A says that a shorted diode in an alternator can discharge a battery. Technician B says that dirt on the battery can cause it to discharge. Which technician is correct?
a. Technician A only
b. Technician B only
c. Both Technicians A and B
d. Neither Technician A nor B
c. Both Technicians A and B
Both technicians are correct. Technician A is correct because a diode should block the flow of electricity from the battery into the alternator and if a diode were shorted, current would be drained from the battery. Technician B is correct because dirt combined with moisture in the air can cause some electric current to flow between the terminal posts of the battery. Answers a, b, and d are not correct because both technicians are correct.
