IGNITION COIL RETROFIT GUIDE

Have Questions? Call 855-944-3571 or email info@wpowereq.com

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:

Tools recommended for this retrot:

• Flat head screwdriver

• Electric drill

• Screw driver bit extension

• Phillips screwdriver bit for drill

• 10mm socket for drill

• 8mm socket for drill

Ignition Coil

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.
