205a 205b short answer

Question 1

What is the purpose of flashing an alternator

Answer 1

Restores residual magnetism b.c if the rotor has lost magnetism the alternator will not charge

Question 2

What is the purpose of full fielding?

Answer 2

Test for faulty voltage regulator

It will bypass voltage regulator

Question 3

Current must be flowing to check for voltage ____ between alternator and batteries/loads and must be eqaul to _______ _________

Answer 3

loss, alternator output

Question 4

Voltage loss on 12V?

Voltage loss on 24V?

Answer 4

12v- 0.5V

24V - 1V

Question 5

2 tests for alternators

Answer 5

Rated output

Regulated Voltage

Question 6

What alternator output must be within 10% of spec

Answer 6

Rated output

Question 7

The regulated voltage for a 12V

For a 24V

Answer 7

12-v 13.8-14.8v
24v 27.6V-29.6V

Remember that a 24V is just double of 12V

Question 8

When performing a regulated voltage test how much (percentage) current (max) should be flowing when checking???

Answer 8

30%

Question 14

the maximum output of an alternator is limited by

Answer 14

inductive reactance

Question 15

the charging system has two major circuits

Answer 15

output and field circuit
