GPP Electroshers 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).
If the Voltages are OK, go to procedure 2.
Flash generator (Follow procedure 8).
Restart procedure 1.
If 12 Volts AC are still not present, go to
procedure 3.

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 signs.
