GPP ELECTROFISHER
USER’S MANUAL
2016
IMPORTANT!:
High voltages are present when
generator is running. Only qualified personnel should
attempt high voltage measurements. We suggest
forming a barricade around the test area and posting
!
!
Check all the connector pairs resistance to Generator ground.
2.5 and 5.0 GPP:
1 & 2 / 3 & 4 (See Fig. 2.1)
7.5 GPP:
1 & 2 / 3 & 4 / 5 & 6 (See Fig. 2.2)
9.0 GPP:
1 & 2 / 3 & 4 / 5 & 6 (See Fig. 2.3)
All of the pairs should show open or high resistance (>0.5 Meg-
ohm).
• Next, check insulation between winding pairs. If resistance
measures low, the wire or generator insulation is bad.

PROCEDURE 2:
TEST FOR CONTINUITY AND HIGH VOLTAGE AC OUTPUT
Fig. 2.1:
2.5 & 5.0 GPP
Fig. 2.2:
7.5 GPP
Fig. 2.3:
9.0 GPP
PROBLEM: NO OUTPUT FROM GPP ELECTROFISHER (CONT.)
If the Voltages are LOW or absent go to procedure 3.
If the Voltages are OK, go to procedure 6.
If low resistance is measured, go to procedure 5.
• With generator running, check for High Voltage on generator
connectors. (See wiring diagrams at the end of this document).
• 2.5 and 5.0 GPP: Check each of the High Voltage terminal pairs on
the output connector for aprx. 360 Volts RMS AC. Pairs: 1 & 2 and 3
& 4 (See Fig. 2.1). 7.5 GPP: Check each of the Voltage terminal pairs
on both of the output connectors for approximately 115 Volts
• RMS AC. Pairs: 1 & 2, 3 & 4 and 5 & 6 (See Fig. 2.2).
• 9.0 GPP: Check each of the Voltage terminal pairs on both of the
output connectors for approximately 67 Volts RMS AC. Pairs: 1 & 2,
3 & 4 and 5 & 6 (See Fig. 2.3). Also, check for
• 115 Volts RMS AC on the smaller 2-pin connector.
SHUT DOWN GENERATOR!
