What are the first two things you do when preparing to troubleshoot an electrical fault?
Verify the fault.,
Check battery power at the battery.
If the vehicle is having a no crank no start issue which one of these will you need to check?

Can searching for voltage drop in a circuit damage your multimeter?
No, the test is done in parallel of the circuit.
Can checking resistance damage your multimeter?
No, but the meter can damage sensitive equipment on the vehicle.
As wire size numbers get larger how does that relate to the size (diameter) of the wire?
Wires get smaller when the wire size numbers get bigger.
What is a coil winding?
A conductive wire wrapped in a loop to create a magnetic field.
What are two ways of telling which post on a battery is positive?
Size of the post, Marked in the plastic of the battery.
What is voltage drop?
Difference in electrical pressure between two points in a circuit.
Can an amp test damage your multimeter?
Yes it puts your meter in series and can blow the fuse.
When testing the alternator to see what kind of condition it is in, where do you put the two probes of the multimeter?
Between the positive post on the alternator and the case of the alternator.
What is the difference between fuses and circuit breakers?

Fuses are a one time use item.
Connecting batteries in series parallel doubles what?
Voltage and Amperage
What is a fuseable link?
A piece of wire that is four gauges higher (smaller) than the rest of the circuit to protect it from heat and shorting out.
