Electrical Theory
V= IR is...
Ohms law
This breaks the circuit in case of excess amperage
Fuse
A starter engages this to turn the engine
The alternator should charge the battery around this voltage
13-14 volts
When a battery is _______ we shouldnt attempt to charge it
Frozen
If one bulb is out this should be checked
Bulb filament
A window motor reverses directions by this occuring
Switching Polarity (Power and Ground)
A starter should never be cranked longer than ____ for testing
15 seconds
When installing an amp clamp to test output from the alternator. We increase load on the battery untill it drops below what voltage to check total output
9.6v
Tests the batteries CCA
Load Test
This is a cause of excess resistance often green in color
Corrosion
This makes the blower motor in the car operate at different speeds by regulating how much amperage/voltage reaches the motor
Blower Motor Resistor
This part moves the starter gear out to engage the flyweel when actuated
Starter solenoid
This part drives the alternator
Serpentine Belt
A fully charged battery is at _______ Volts
12.6
The opposition to current flow
Resistance
RKE Stands for
Remote Keyless Entry
This is how the starter is grounded
Case ground- To the engine
When replacing an alternator. This must be unhooked first
Negative Battery Terminal
A battery uses electrolytes to allow electrical charge to flow between the anode and _____
Cathode
Voltage Drop
A coil of a relay should measure this many ohms of resistance
If a starter motor cannot turn the engine but electrically tests ok what must we check next
Ensure the engine and pulleys can spin by cranking the engine by hand
This converts AC to DC
Diode or Rectifier Bridge
This type of battery requires special charging procedures
AGM
