Overview & Operation
If you need assistance during this installation call
Tele ex Marine Technical Services at 610-495-7011.
Ignition Interrupt Switch Overview
This switch includes a lanyard clip which holds the plunger of the switch in position to allow engine operation.
A lanyard extends from the clip and is connected securely to the operator. If the operator moves away from the
controls, the clip is pulled free, releasing the plunger and stopping the engine.
Operation of the Ignition Interrupt Switch
Before each motor start, ensure the Lanyard Fork Clip is properly seated over the switch and that it rotates freely. If the
lanyard is cut, worn or frayed, it must be replaced.
Start the engine and test the switch by pulling the lanyard fork clip free from the switch. The engine should stop.
Installation Instructions
All wiring, connections and terminations should be done in accordance with ABYC Spec E 11-03. Before drilling, check
behind the gunwale or panel for suf cient clearance and space around wires, tubes, pipes and other obstructions.
1. If installing the switch as a retro t, remove the 4 mounting screws that retain the bezel. Remove the bezel. Ensure the
cutout is large enough to allow the interrupt switch to pass through the gunwale when mounted. (See Exploded View on
page 3 for switch location.)
2. If installing the control for the rst time, use the template (supplied with the control) to cutout the gunwale.
3. Insert the switch from the rear of the gunwale or from the front. Your choice will depend on the design of your boat
and access to the cavity between the hull and the gunwale.
4. Orient the switch according to the Exploded View diagram before inserting the switch into the space provided in the
control mounting plate, the cutout and into the bezel.
5. Insert the 4 mounting screws through the bezel cutout and into the control mounting plate.
6. Assemble the bezel Insert onto the bezel and add the Interrupt Switch retaining nut. Torque to 40 50 inch pounds
(3.5 to 4 foot-pounds)
7. Insert the lanyard clip under the Interrupt Switch plunger. Pull rmly on the lanyard to verify that the clip snaps free.
Ensure the nut remains tight, re-torque if necessary. Reattach the lanyard clip to the switch.
8. Complete the Interrupt Switch wiring into the engine electrical circuit according to the instructions below.
9. Complete all testing of the Interrupt Switch function according to the instructions on the following page(s).
If the engine fails to stop, recheck all wiring. Should the
engine fail to start or stop, or resume running with the
lanyard fork removed, consult your local marine dealer
for assistance. Do not change the length of the lanyard
or use another manufacturers lanyard on this interrupt
switch, as either may affect switch operation. CH1700 Ignition Interrupt Switch Installation Manual

I/O and Inboard Wiring
(basic wiring; no speci c manufacturer)
Exploded View
I/O or Inboard Use ONLY (Normally OPEN)
1
Disconnect all batteries and any auxiliary on-board or dockside power supplies.
2
Locate the purple ignition switch-to-coil wire; See Diagram A below.
3
Cut the purple wire, strip the ends and install two (2) insulated crimp-on 1/4 inch female disconnect terminals. A
crimping tool designed for insulated terminals MUST be used.
4
Attach the female disconnects to each of the male terminals on the Interrupt Switch
5
Recheck all connections.
6
Install Lanyard with the Fork Clip seated on the Plunger.
7
Reconnect battery.
8
Start engine. If engine does not start: disconnect battery, recheck all electrical connections, reconnect battery, restart
engine.
9
Remove Lanyard. Engine should stop immediately.
Use 16 AWG Purple stranded, insulated marine
quality wire for I/O or inboard applications.
(Type HDT, THW, UL 1426 or equivalent.)

Be
sure this wire goes directly to the coil and not to
the instrument or alternator circuit. Selecting
the incorrect wire will result in improper switch
operation which could lead to serious injury.

Use 16 AWG Black stranded, insulated marine quality wire for all outboard applications. (Type HDT, THW,
UL 1426 or equivalent.) This interrupt switch is designed for use with outboard motors that are equipped
with grounding-type emergency stop circuits only.
Outboard Use ONLY (Normally CLOSED)
1
Disconnect all batteries and any auxiliary on-board or dockside power supplies.
2
Remove Engine Cover
3
Locate the correct color emergency stop wire for your motor. (See Reference Table 1 below.)
4
Measure and cut two lengths of black 16 AWG marine quality wire of suf cient length to connect one Interrupt Switch terminal
to the Emergency Stop Wire and the other terminal to a System Ground. (See Diagram B below.)
5
Strip one end of each wire and crimp on an insulated 1/4 inch female disconnect terminal. A crimping tool designed for
insulated terminals MUST be used.
6
Attach the female disconnects to each of the male terminals on the Interrupt Switch.
7
Attach the other end of one wire to the Emergency Stop Wire, using a suitable insulated wire connecting device. (See
Reference Table 1 and Diagram B.)
8
Attach the other end of the second wire to the ground point, using a suitable insulated wire connection device as shown in
Diagram B.
9
Recheck all connections. Install the Lanyard with the Fork Clip seated over the Plunger
10
Replace engine cover and reconnect battery.
11
Start engine. If engine does not start: a) disconnect battery; b) remove engine cover; c) recheck all electrical connections;
d) replace engine cover; and e) restart engine.
Remove Lanyard. Engine should stop immediately
If the engine fails to stop recheck all wiring. Should the engine fail to start, stop, or resume running with the
lanyard fork removed, consult your local marine dealer for assistance.
