This comprehensive retrot guide is for replacing the ignition coil on
Westinghouse’s iGen2500 and iPro2500 inverter generators. The purpose
of this retrot is to limit the overspeed of the engine. This will eliminate
overheating issues due to engine overspeed.
Instructional videos for how to properly replace the ignition coil
are available at the links below:

Step 1: Using the power drill, remove the top two Phillips
head screws on the pull cord side of the generator. It is
recommended to use a bit extension to help reach deep
set screws.
Step 2: Turn the generator to the mufer side and remove
the 6 Phillips screws holding the mufer grate in place.
Step 3: Turn the generator to the non-pull cord side and
remove the top three Phillips screws. Next, remove the
spark plug access cover on the top of the unit.
Step 4: Turn the generator to the control panel side and
remove the 4 Phillips screws indicated in the image to the
left. Then remove the Phillips screw holding the OFF-
RUN-CHOKE switch in the upper right hand part of the
control panel. Once these screws are removed, pull from
the bottom of the control panel assembly to detach it.
NOTE: Be sure not to remove the 2 screws at the bottom
edge of the control panel.
Step 5: Pull back the rubber fuel collector under the gas
cap and remove the clip with a athead screwdriver. This
clip secures the side panels together.

Step 6: On the bottom of the pull cord side of the
generator remove the 3 10mm bolts that hold the side
cover on.
Step 7: Detach the pull cord side cover. Start by pulling
the mufer side of the cover and work towards the gas
cap side. There is a groove under the gas cap that can
be detached by pulling upward and outward. Once the
panel is removed let it lean outward so you can access
the engine. The recoil does not need to be removed to
perform ignition coil replacement.
Step 8: In the center of the unit lift up on the gas tank to
access the ignition coil assembly. Remove the 8mm bolt
that holds the ignition coil to the engine.
Step 9: Pull the spark plug boot off of the spark plug on
top of the engine.
Step 10: Unplug the three wire connections to the ignition
coil assembly. Once the ignition coil is detached, discard it.

IMPORTANT
Step 11: Check to see that the connection from the
alternator to the inverter board is connected and secure.
If it is unplugged make sure to plug it in. This connector is
a two wire located behind the inverter module.
NOTE: If there are any connections to the control panel
or inverter board that are not connected, make sure to
connect them.
Step 13: Route the ignition coil wire under the gas
tank and then reconnect the 3 connectors that you
disconnected in step 10. There should be a 4 wire
(orange, blue, red, black), 3 wire (brown, white, black)
and 1 wire (yellow).
Step 14: Once the wires are connected take the 3 wire
connector (brown, white, black) and 1 wire (yellow) and
wrap them around the mount where you will screw in the
ignition coil. See image to the left for proper placement.
The 4 wire connector will stay loose at the bottom.

Step 15: Secure the ignition coil assembly with the 8mm
bolt that you removed in step 8. NOTE: Be sure not to
overtightened as the plastic will break.
Step 12: Take the new ignition coil provided and install it
by rst pushing the spark plug boot onto the spark plug
until you hear a click.

Step 16: Reattach the pull cord side cover. Start by
guiding the top right of the panel around the groove under
gas cap. The back side of the rubber fuel collector has a
plug that needs to be guided into place before the sides
are reconnected.
Step 17: Screw in the Phillips screw at the front right of
the case to help reattach the clip that was removed in
step 5.
Step 18: Using a at head screw driver reattach the clip
under the rubber fuel collector that was removed in step 5.

Step 19: Screw in the 2 Phillips screws removed in step 1
from the top of the generator on the pull cord side.

Step 20: Reinstall the mufer grate by tilting the bottom in
rst so that the tab lines up. Push in the top two tabs so
that the panel is ush. Then screw in the 6 Phillips screws
removed in step 2 that hold the mufer grate in place.

Step 21: Turn the generator to the non-pull cord side of
and screw in the top two Phillips screws. Next, install the
spark plug access cover that was removed in step 3.
Step 22: Turn the generator to the control panel side and
reinstall the control panel assembly by tipping the top
forward so that the tabs line up. Screw in the 4 Phillips
screws removed in step 4. The two longest screws go on
top of panel. Reinstall the OFF-RUN-CHOKE switch in
the upper right hand part of the control panel and secure
with Phillips screw. IMPORTANT: Make sure the switch is
installed in the correct orientation with the off state being
vertical.

Step 23: Replace the 3 10mm bolts at the bottom of the
pull cord side of the generator.
Step 24: Make sure to take the generator outside to a
well ventilated area and run it to conrm there are no
issues with installation. Switch the economy mode on and
off and check for major RPM changes.
