1. Which of the following best describes the primary function of an RV
converter?
A) Converts propane to electricity
B) Converts AC power to DC power
C) Converts DC to AC
D) Stores electrical current
-Correct Answer-: B) Converts AC power to DC power
Rationale: The converter changes 120V AC power to 12V DC power used by RV
systems and appliances .
2. A GFCI outlet is designed to:
A) Protect against power surges
B) Protect users from ground faults
C) Regulate amperage flow
D) Provide additional voltage
-Correct Answer-: B) Protect users from ground faults
Rationale: GFCI detects imbalances between hot and neutral conductors to
prevent electric shock .
3. What type of battery is most commonly used in RV house systems?
A) Lithium ion
,B) Alkaline
C) Deep-cycle lead acid
D) Nickel metal hydride
-Correct Answer-: C) Deep-cycle lead acid
Rationale: Deep-cycle batteries provide sustained power over long periods and
are rechargeable .
4. The term "amp-hour rating" refers to:
A) Voltage capacity
B) Battery storage capacity over time
C) Instantaneous current draw
D) Inverter efficiency
-Correct Answer-: B) Battery storage capacity over time
Rationale: Amp-hours measure how many amps a battery can deliver in one
hour .
5. Which propane pressure is typical after a two-stage regulator in an RV LP
system?
A) 30 psi
B) 5 psi
C) 11 inches water column (WC)
D) 20 inches WC
-Correct Answer-: C) 11 inches water column (WC)
Rationale: The second-stage regulator reduces pressure to 11 inches WC for safe
appliance operation .
6. What tool is used to check LP gas leaks in RV systems?
A) Flashlight
B) Multimeter
C) Soapy water solution or leak-detector spray
D) Wrench
-Correct Answer-: C) Soapy water solution or leak-detector spray
Rationale: Soap bubbles form at leak points when pressure is applied .
, 7. An RV refrigerator typically operates on:
A) AC only
B) DC only
C) AC, DC, and propane (3-way system)
D) Solar only
-Correct Answer-: C) AC, DC, and propane (3-way system)
Rationale: Three-way refrigerators provide flexibility for shore, battery, or LP
operation .
8. When servicing a 12-volt lighting circuit, technicians should first:
A) Replace the fuse
B) Verify power source and ground
C) Cut the wire
D) Bypass the fixture
-Correct Answer-: B) Verify power source and ground
Rationale: Always verify the basics of power and ground before assuming a
component is bad .
9. What is the primary cause of water leaks in RV roof seams?
A) UV damage
B) Dried-out sealant
C) Bird droppings
D) Pressure washing
-Correct Answer-: B) Dried-out sealant
Rationale: Over time, sealant shrinks and cracks, allowing water intrusion .
10. The water heater bypass valve is used to:
A) Increase water flow
B) Isolate the heater during winterization
C) Clean the tank
D) Release pressure
-Correct Answer-: B) Isolate the heater during winterization
Rationale: Bypassing prevents antifreeze from filling the water heater tank .
