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).
