Circuit tester

The circuit inside the diode rectifiers is as shown in the chart above.

Check continuity between each terminal by using a circuit tester.

The rectifier is normal when continuity is as follows:

Checking table for degital circuit tester

Degital circuit tester			Apply red		needle of the circuit tester
			Yellow	Yellow		Orange	Gray
		Yellow	-	No continuity		No continuity	Continuity
Apply black	needle	Yellow	No continuity	-		No continuity	Continuity
of the circuit tester		Orange	Continuity	Continuity		-	Continuity
		Gray	No continuity	No continuity		No continuity	-

NOTE 1 : Because of the difference of measuring method between the analogue circuit tester and the digital circuit tester, polarity of tester needles should be reversed.

NOTE 2 : "Continuity" means forward direction characteristics of the diode, and different from short circuit condition

(in which a pointer of the tester goes out of its normal scale), shows resistance to some extent. When results of the checking indicates failure even in one section, replace with a new one.

NOTE 3 : Some analogue testers like "Simpson" brand operate as some as digital testers.

(4)AC RECEPTACLES

Check that no live part or wire or plastic part is burnt.
