Just a few i couldnt find the answer to?

Technician A says a battery with an open-circuit voltage of 12.40 or


higher can be load tested. Technician B says an OCV of less than 12.40


means the battery must be charged first. Who is right?


a. A only


b. B only


c. both A and B


d. neither A nor B





Technician A says to replace the brushes if they are worn to half or


less of new brush length. Technician B says to replace the brushes if


they are worn to 1/4-inch (6-mm) or less in length. Who is right?


a. A only


b. B only


c. both A and B


d. neither A nor B





Technician A says the spark occurs when the contact points open.


Technician B says the spark occurs when the coil magnetic field


collapses. Who is right?


a. A only


b. B only


c. both A and B


d. neither A nor B





Technician A says a Hall-effet switch uses the presence or absence of


a magnetic field to switch a supplied voltage on and off. Technician


B says the Hall-effect voltage switches on when a steel blade


enters the air gap of a Hall-effect switch. Who is right?


a. A only


b. B only


c. both A and B


d. neither A nor B


To determine if the primary circuit is opening and closing, make a


a. triggering test with a digital logic probe


b. spark test at the ends of the spark-plug cables


c. voltage test at the battery


d. test of the coil primary-winding resistance


In an electronic distributor with vacuum advance, hesitation and


stumbling during acceleration may be caused by


a. an inoperative vacuum-advance unit


b. an intermittent open in the pickup-coil leads


c. an inoperative centrifugal-advance mechanism


d. a defective electronic control module (ECM)|||you need to answer these questions your self/these types of thingys always show up and you need to search the answers and do your homework yourself
