A.V.R.

AVR
4-8. CHECKING A.V.R.
(AUTOMATIC VOLTAGE REGULATOR)
1) Features
This A.V.R. operates to control the field
current in order to maintain the output voltage
for the AC current, which generated by the
magnetic flux by the field coil.
2) A.V.R. trouble may be identified by simply
looking at the A.V.R., or by the inter-lead
resistance with a tester, or actually mounting
it in the generator and operating it.
Replace the case where the resistance is
significantly deviated from the measured new
one.
