Voltage/Current/Resistance/Amps
What is resistance
The opposition to the movement of electrons
What is V-1, explain
Checking your power source
What 3 things should a tech look for when reading a wire diagram? Draw on the board and explain
Power, Ground and Load
What does DC mean on a Multi-meter
Direct current
What does CCA stand for and what does it mean
Cold cranking amps, how many amps the battery can put out at a certain temp
What is amperage
The flow of electrons through a conductor
What is V-4 explain your answer
Checking the positive side of the circuit draw on the board
What is a splice, draw it on the board
a point in the circuit where several wires come together
Draw a ckt on the board using the meter explain where you would do a voltage drop on the positive side of the load using the meter.
Was it correct????????
What is a voltage regulator
Voltage measured in?
Volts
Explain what what you are checking and where you are checking, when you are checking V-2. Draw it on the board and explain.
Voltage drop across the load. Power coming in and power coming out.
When reading wire color and what would B/r
Black with a red stripe
Draw a CKT on the board and do a voltage drop on the load. Setting up your meter and showing your work on the board.
Was that correct??????????
What part of the Alternator has current induced in it and is the output for the Alternator
The stator
Draw a circuit and show where you would check for voltage loss through a battery cable. Where would you make the checks. What is an acceptable voltage loss in this wire?
.2- to .5
Why is checking voltage drops important?
You are checking the resistance of the part or wire.
Explain the difference between a 12 gauge wire and a 3 gauge wire
The higher the number the smaller the wire
You are doing a OHMs test on a motor that is suppose to draw 10 amps. Draw the ckt on the board and show us how you would complete the ohms test using the meter. We are looking for the correct meter setting and sequence for doing an ohms test.
Was that correct?????????????????????????????? The part must be removed from the ckt before it can be tested.
What is the job of the Ait brushes
To provide battery current to the alt rotor
Show how you would check the resistance/ohms of a part using Muti-Meter on the board
The part needs to be removed for the circuit before testing
Define voltage and draw on the board voltage moving through a circuit and show and explain the voltage loss
ckt and losses being shown
Draw on the board a wire diagram with a switch, fuse, 5 gauge wire, a relay, load. Control the load from the GND side of the circuit.
Lets seeeeeeereeeee!
Do a ohms test on the relay on the desk. Using the meter explain in detail what side of the relay you are checking and what is happening while you are checking the relay.
You should be doing a ohms test on the control side of the relay ckt
What is the name of the charging system that allows the computer to control current flow to the Alt brushes. Also you have to correctly repair the wire at the front of the class
Smart charging system........................
