Receptacle Panel - Briggs & Stratton 86262GS Familiarization & Troubleshooting Manual

Some portable generators, such as the "XL" and "MC"
series, are equipped with a power regulator circuit board
and a system control circuit board (Figure 2.58).
Operationally, this system is the same as units with an
electronic voltage regulator. However, some of the electronic
regulator functions are handled by the power regulator
board, while other regulator functions are handled by the
system control board.
Operation of this type of system can be described briefly as
follows:
Figure 2.58 — Regulator And System Control Boards
• An actual (AC) power winding voltage signal is delivered
to the system control circuit board.
• Stator excitation (DPE) winding (AC) output is
delivered to the power regulator circuit board.The
power regulator board rectifies this current (converts it
to DC).
• The system control circuit board electronically
compares the actual (AC) power winding voltage to a
preset reference voltage. If actual voltage is less than the
preset reference voltage, the system control board
signals the power regulator board to turn on and
increase current flow to the rotor.This causes the
rotor's magnetic field strength to increase and actual
voltage to increase.When actual voltage is more than
reference voltage, system control board action signals
the power regulator to shut down.

RECEPTACLE PANEL

Some portable generators use the rear bearing carrier cover
plate as the receptacle panel.

Section 2 • Generator Components & Systems
Other models employ a separate receptacle panel.When
electrical receptacles are mounted on the bearing carrier
cover, stator (AC) output leads are routed out of the stator
and connect directly to the receptacles or to receptacle
circuit breakers (Figure 2.59).
Figure 2.59 — Receptacles On Bearing Carrier Plate
When a separate sheet metal control and receptacle panel is
used (Figure 2.60), stator (AC) power winding output leads
will usually be attached to a black connector plug.
Figure 2.60 — Receptacles On Separate Control Panel
The black connector plugs into a 6-pin receptacle on the
control panel. Other units have voltage regulator sensing
leads #11 and #22 and the excitation leads (2, 6, 1 and 4)
attached to a 9-pin connector plug.That plug is then
connected into a 9-pin connector on the panel.
