5.12 Main Circuit Short Check
Check No.20
Check to make sure that the voltage between (+) and (–) of the diode bridge (DB1) is
approximately 0 V before checking.
Measure the resistance between the pins of the DB1 referring to the table below.
If the resistance is
∞
or less than 1 k
Ω
, short circuit occurs on the main circuit.
