Emergency Stop Switch Test; Tachometer Circuit Tests - BRP Evinrude E-Tec Series Service Manual

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).

1. Purple lead
2. Black lead
3. Gray lead
STEP 1
Connect the red meter lead to the tachometer pur-
ple wire and the black meter lead to the tachome-
ter black wire (key ON, outboard NOT running).
If meter shows battery voltage, go to STEP 2.
•
If meter shows less than battery voltage, check
•
the purple, red/purple, and black wiring circuits,
fuse, key switch, and battery connections.
STEP 2
Disconnect gray and black wires at tachometer.
Set Fluke 29 Series II meter, or equivalent, to Hz
scale. Connect meter between gray wire and
black wire. With outboard running at 1000 RPM,
meter should indicate 90 to 105 Hz.
If meter reads 90 to 105 Hz, replace tachome-
•
ter.
If meter reads low or no signal, confirm output
•
on gray wire at pin 16 of EMM J1-A connector.
– Reading OK – Check condition of tachometer
circuit (gray wire). Repair as needed.
– Reading not OK – Check connection at EMM;
replace faulty EMM.
