Question

before you disconnect the service battery from the discharged battery, it is good practice to place a load on the charged battery by: select one: a. turning on the headlights. b. turning off the air conditioning. c. turning all accessories on then off. d. placing the vehicle in drive.

Explanation:

Turning on the headlights places an electrical load on the charged battery. Turning off the air - conditioning reduces the load. Turning accessories on then off doesn't consistently place a load. Placing the vehicle in drive doesn't directly place an electrical load on the battery.

Answer:

A. turning on the headlights
