SWITCH SPECIFICATIONS: Case to Ground: 2 AMP,

SWITCH ADJUSTMENT:

Switch adjustment is not recommended. Improper setting
may result in damage to engine. Switch is factory set at 1/2”
below center of sight window. The test button must be
removed for switch adjustment.

Removing the test button assembly for switch adjustment:

• Unscrew the test button using a deep 5/8” socket.

Make sure the socket completely covers the test
button, not just the rubber boot. If the rubber boot is
inadvertently removed, care must be taken to ensure
the return spring and actuation pin are not lost.

Actual Switch Adjustment: Refer to figure 2 and follow these
instructions:
• Remove the cover of the condulet housing (A) by

unscrewing the 6 screws(B).

• Rotate the slotted set screw(C) counter-clockwise to lower

the switch trip point.

• Rotate the slotted set screw(C) clockwise to raise the

switch trip point.

• Attach the wire from the controller to the low tension

terminal on the magneto.

Replacing the test button assembly after switch adjustment:

• Before reinstalling the test button, check the O-ring

for any damage. If damaged, replace O-ring.

• Re-install the test button using the 5/8” socket.

Do not

overtighten! A snug fit is all that is required to
retain the test button and provide a water-tight
seal.
