If the spark line is totally flat, is longer than 2 ms, and is less than 500 volts, there is a good chance that __________ .
20. Technician A says that an ignition
system must generate sufficient voltage to
force a spark across the spark plug gap.
Technician B says that the ignition system
must time the arrival of the spark to
coincide with the movement of the engine's
pistons and vary it according to the
operating conditions of the engine. Who is
correct?
O a. Technician A
O b. Technician B
c. Both A and B
O d. Neither A nor B
A spark plug is examined and it is notice that the plug is fouled with a stick black substance. Tech a says that the engine is running too rich (too much fuel). Tech b says that the plug is oil fouled and that a proper burning plug would be light in tan color. Who is correct?
