Technician "A" states that Deep-Cycle batteries should only be used for starting batteries on large
outboards because of the large amounts of current that they can provide. Technician "B" states that
Deep-Cycle batteries are designed to discharge repeatedly but to a very low voltage and are commonly
used as house batteries. ---ANSWER-----Technician "B"
When checking and refilling a lead acid battery's electrolyte level only_______ should be used. ---
ANSWER-----Distilled Water
During the actual _________, the electric current becomes very hot. This is sometimes referred to as
______. ---ANSWER-----Ignition Event, Spark
_________ refers to the timing, relative to the current piston position and crankshaft angle, of the
release of a spark in the combustion chamber near the end of the compression stroke. ---ANSWER-----
Ignition Timing
When a cylinder's normal combustion event does not take place, the result is referred to as a _______, -
--ANSWER-----Misfire
Whenever a magnetic field is moved over or though a coil of wire, an electric current will be produced.
The direction of current flow will be based on the amount of winding's of wire which pass the magnet. --
-ANSWER-----False
,Understanding the phenomena of electromagnetic induction and stating the current flow was suddenly
interrupted or stopped. inducing a pulse of electrical current back into the coil of wire would be an
example of a self -inductive type circuit which is commonly used on the secondary winding's of an
ignition coil pack. ---ANSWER-----False
Technician "A" states that when troubleshooting an outboard starting system, the first step is to
preform a voltage and load test on the battery and make sure it meets the MCA (Marine Cranking Amps)
required to start the outboard. Technician "B" on the other-hand states that the first step should be to
check for 12v power at the battery side of the start solenoid then while the key is in the cranking
position then check for 12v on the starter side of the solenoid. ---ANSWER-----Technician "A"
Using the wiring diagram above answer the Following.
1. What color wire connects the overheat temperature sensor the engine terminal block? [ Select ]
["Orange", "Red", "Yellow", "White"]
2. What color wire connects the ignition coil to the points on the breaker plate? [ Select ] ["White",
"Red", "Orange", "Yellow"]
3. If the White wire running from the breaker plate to the engine terminal block were to fail which
circuit would be affected. [ Select ] ["Starting circuit", "Choke circuit", "Ground return circuit",
"Tachometer circuit"]
4. How may stator leads are utilized on this model charging system? [ Select ] ["4", "3", "5", "6", "1", "2"]
5. Jumping power across Neutral interlock switch would in turn by-pass the key switch and start the
outboard. ---ANSWER-----1: Orange
2: White
3: Tachometer circuit
4: 3
5: Starter Solenoid
Select the Correct Response:
A. Voltage is the actual movement of electricity.
B. Current can be compared to water pressure.
C. Resistance is the force that opposes the flow of current.
D. The size of the adjoining pipe and the restriction it presents to the flow of water can be compared to
electrical current ---ANSWER-----C. Resistance is the force that opposes the flow of current.
, Technician "A" states that alternating current switches back and forth, (negative to positive and back
again), in a cycle of 120Hz in the United States. Technician "B" claims its actually 60Hz for the common
frequency used for utilities in the United States. ---ANSWER-----Technician "B"
One Limitation of AC (Alternating Current) is that with today's technology, it's not possible to store AC
current for late use. AC produced voltages must therefore be converted to DC before storage in a
battery is possible. ---ANSWER-----True
Voltage is referred to as electrical pressure, if compared to a reservoir of water, the less water in the
reservoir the higher the pressure or electrical voltage it contains. ---ANSWER-----False
Current is the actual movement of the electric charge, this is referred to as? ---ANSWER-----Amps
Technician "A" states that electrons flow from negative to positive in an electrical circuit. Technician "B"
states that although that is widely accepted, factually electrons flow from positive to negative in an
electrical circuit. ---ANSWER-----Technichian "A"
Resistance is the force which works to stop the flow of current. The unit used to measure resistance is
Ohms. ---ANSWER-----True
Using the Ohm's Law equation (I=V/R), an electrical circuit with 12vdc (Volts DC) and 5ohm's of
resistance, what is the current flow? ---ANSWER-----2.4 Amps
One of the most common problems in outboard electrical systems is corrosion, keeping contacts and
terminals clean can make all the difference. ---ANSWER-----True
Technician "A" states that since the fuel pump is accidentally grounded after the load it is a textbook
example of an open circuit since the current will not stop flowing not allowing the fuel pump to shut off.
Technician "B" states that since the fuel pump circuit is grounded after the load its actually a textbook
example of a grounded circuit allowing the fuel pump to run indefinitely. ---ANSWER-----Technician "B"
A bridge rectifier is used to convert AC current to DC, so the outboards systems can use the generated
power. This rectifier utilizes a set of diodes to achieve this goal. the byproduct of this action is the
generation of heat and most bridge rectifiers can be identified by? ---ANSWER-----Being packed with
silicone
