GPP ELECTROFISHER
ADVANCED TROUBLESHOOTING

• Construct a test load using a plastic bucket with the
metal handle removed (Fig. 9.1).
• Connect the test load to the GPP Electrofisher as shown
(Fig. 9.2).
• Add tap water to the bucket.
• Set the “Mode Switches” on the GPP Control Box to AC
& 120 PPS/ 60 AC.
• Start the generator.
• Control the GPP output with the “Emergency Shut
Down” switch or Foot switch.
• By turning the “Percent of Range” control up to 100%
and checking the amp meter on the GPP Control Box,
the correct load can be determined. See below:
• The amp meter will increase to the maximum as you
turn up the “Percent of Range”.
• The load may be increased by slowly adding table salt
to the water in the bucket.
• If the load is too great for the range selected, the GPP
will operate erratically.
• If the amp meter starts to show a decrease in amps
or is erratic as the “Percent of Range” nears 100%
the generator is over-loading. The water may need to
be changed, or decrease the portions of electrodes
immersed in the water.
WARNING:
keep all personnel clear of test
load while generator running.

IMPORTANT! Danger!
High Voltage is present during test load procedure.
Every effort should be made to keep all personnel away from test load
bucket. It may be necessary to form a barricade around testing area and
post appropriate signs warning of High Voltage.
