Exam 28: Starting System Fundamentals

Cars built before the early 1960s that were equipped with a remote starter relay MOST-Likely had:

All of the following statements are true EXCEPT:

Which of the following is LEAST-Likely one of the basic parts of a motor?

What is the purpose of brushes on the commutator?

The ___________________ between the pinion and ring gears provides the starter with the leverage needed to turn the crankshaft against engine compression.

Which of the following is LEAST-Likely a starter driver part?

While having a discussion, Technician A says that a solenoid has contact points, whereas a relay uses a movable iron piston attached to a contact disc. Technician B says that a relay has contact points, whereas a solenoid uses a steel piston moved against a contact disc by magnetism. Who is correct?

All of the following statements are true EXCEPT:

The starter motor must spin at ____  rpm in order to turn the engine at normal cranking speed to start the engine, which is about 200-250 rpm.

The armature core is wrapped with many loops of heavy insulated copper wire called ____________________.

What is the relationship between starters and electromagnetism?

The ratio between the pinion and ring gears is about 8:1.

____ are made of heavy copper ribbons wound around soft iron cores called pole shoes.

Multiple loops make up an armature.

What is the relationship between loops and the armature?

A(n) ____________________ disengages from the engine at startup, preventing the engine from driving the starter.

What is the purpose of the starter's relay?

While having a discussion, Technician A says that most solenoids are mounted on the top of the starter motor. Technician B says some solenoids are mounted in a remote location. Who is correct?

Some starter motors used since the mid-1980s have no field coils but have permanent magnets instead.

If the starter is forced to rotate at speeds above 1,000 rpm, it could be destroyed by centrifugal force.
