.The 3400-B instruments, while complex, can generally be
repaired in the field by isolating problems to one or two
modules by the process of elimination. The following list
provides some troubleshooting hints for various situations.
Instrument fails to display when power is turned on.
 Batteries are discharged below cut-off voltage. Plugging
in the charger will turn on the instrument.
 Check the receptacle into with the charger is plugged.
Power may not be available to operate the charger. On
older models fuses located on top of each battery back
should be checked and replaced with Bussman type
GMW 2 Ampere fuses, if necessary.
Charger lamps come on but unit still does not indicate a
powered on condition. (Older model 3411 gauges have
charger lamps.)
