Electrical control devices include a variety of:

A single pole, double throw switch will use how many wires?

Tech A says a headlamp dimmer switch is a good example of a single pole double throw switch. Tech B says a SPDT switch has one input terminal and two output terminals. Who is correct?

Two types of relay designs are used, the normally open and normally closed. Tech A says the normally open is the most popular type used in automotive applications. Tech B says that current will flow through the contacts out to the load when the coil is energized in a normally open type of relay. Who is correct?

Tech A says that a relay is an electromagnetic switch, which uses a small amount of current to control a large amount of current. Tech B says relay construction contains an iron core, an electromagnetic coil, and a movable armature. who is correct?

Which of the following is an electrical control device (LOAD)?

Tech A says that an ignition switch is an example of a multiple pole multiple throw switch. Tech B says a momentary contact switch can be either a normally open or normally closed contact switch. Who is correct?

Tech A says that a Bi-metallic switch is temperature sensitive and contains a bi-metal element that bends when heated. Tech B says a time delay switch contains s bi-metal strip, contacts, and a heating element. Who is correct?

electrical controls are needed to start, stop, or redirect current flow in an electrical circuit.

The open circuit voltage test indicates the:

Tech A says when disconnecting a battery always disconnect the negative cable first. Tech B says when reconnecting cables always connect the positive cable first. Who is correct?

battery corrosion may be cleaned with:

what test instrument would you use to check the open circuit voltage of a battery?

what test instrument could you use to check the specific gravity of a battery?

a battery with a cold cranking amp rating of 600amps would be load tested at:

the cold cranking amp rating of a battery indicates the available amperage of the battery at what temperature?

A battery capacity (load) test discharges the battery for:

an automotive battery is being repeatedly and severely discharged before it is recharged. Tech A says that this deep cycling shortens battery life. Tech B says that this will have n effect on battery life. Who is correct?

A fully charges 600 CCA battery is load tested. With proper load applies after 15 seconds the voltage reads 10.2 Volts. What does this indicate?

The temperature corrected specific gravity readings of a battery that has been charged for 8 hours are: 1.270, 1.265, 1.270, 1.270, 1.265, 1.265. According to the readings the battery:
