GPP Electrofishers have two 500-watt accessory 12 Volt AC windings.
The accessory output terminals are located on the generator end-
bell.
• Set the GPP Control Box Voltage range switch to off. Adjust
generator engine speed to 3600 RPM using a vibrating
tachometer which is available at most small engine shops.
• Check the 12 Volts AC on the end bell of generator using an AC
Voltmeter (See Fig. 1.1). They should read approx. 14.5 Volts,
60Hz.
2.5 AND 5.0 GPP ONLY:
• Check the 12 Volts AC on the output connector, pairs: 5 & 6 (See
Fig. 1.2).

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 appropriate high voltage warning
