Emergency Stop Switch Test
This switch can be incorporated into the key switch or installed as a separate switch. Either style effectively connects the “M” terminals of the key switch.
The emergency stop switch function grounds the stop circuit wire (black/yellow) when the lanyard clip is removed. One “M” terminal is the ground wire (black) and one “M” terminal is the stop circuit wire (black/yellow).
- Lanyard and clip assembly
- Emergency stop switch, separate from key switch
- Stop circuit wire (black/yellow)
- Ground wire (black)
Install the clip on the emergency stop switch or key switch. Start the outboard. Pull the clip from the switch. The outboard must stop running.
ELECTRIC STARTER TESTS
Starter Solenoid Test
Disconnect the B+ (POS) battery cable at the battery.
IMPORTANT: Disconnect all wiring from solenoid terminals before proceeding with this test. Use an ohmmeter to measure resistance.
STEP 1
Put one ohmmeter lead on the starter positive (+) cable terminal and the other ohmmeter lead on the battery positive (+) cable terminal:
- Ohmmeter must not show continuity (high reading).
- If ohmmeter shows continuity (low reading), replace the solenoid.
- Ground wire (black)
- Starter positive (+) cable terminal
- Battery positive cable (B+) terminal
- “A” terminal (yellow/red)
- “B” terminal (black)
STEP 2
Apply B+ to terminal “A” of solenoid and ground (NEG) to terminal “B” of solenoid. Measure resistance between the starter positive (+) cable terminal and the positive battery (+) cable terminal.
- The solenoid must close with an audible click.
- Ohmmeter must show continuity (low reading).
- If ohmmeter shows no continuity (high reading), replace the solenoid.
After re-installing the solenoid, coat all wires and terminals with Black Neoprene Dip.
No Load Current Draw Test
Securely fasten starter in a vise or suitable fixture before proceeding with this check.
Use a battery rated at 500 CCA (60 amp-hr) or higher that is in good condition and fully charged.
Use an inductive ammeter or connect a 0 to 100 amp ammeter in series with a heavy jumper
between the battery positive (+) terminal and the starter positive (+) terminal. Fluke model 334 or 336, Snap-On model MT110 or EETA501, and various other ammeters should be available through local tool suppliers. Attach or hold a vibration tachometer, such as a Frahm † Reed tachometer, to the starter.
TYPICAL
Complete the circuit with a heavy jumper between the battery negative (–) terminal and the starter
frame. Monitor the starter RPM and current draw.
• At 10,500 RPM the ammeter should show a maximum of 30 A.
