(a) A.V.R. TROUBLE IDENTIFICATION by APPEARANCE
If an A.V.R. electronic part is burnt dark, or the surface epoxy resin melted, it often indicates A.V.R.
trouble.
(b) IDENTIFYING A.V.R. TROUBLE by CHECKING INTER-LEAD RESISTANCE
Check the inter-lead resistance of the A.V.R. with a tester, referring to the following table.
If the tester readings very greatly from the values specified in the table on next page, the A.V.R. is
faulty.
NOTE : Take teater inaccuracy into account in reading the tester.
(c) IDENTIFYING A.V.R. TROUBLE by MOUNTING and OPERATING in THE GENERATOR
SCR or transistor damage cannot be detected by simply looking at the A.V.R. or checking the lead
resistance. Check it by mounting the suspectedly faulty A.V.R. in a normal generator, or mount a
mormal A.V.R. in a generator which fails to generate voltage.
* Checking table for analogue circuit tester.
