Section 05 ELECTRICAL SYSTEM

Subsection 07 (GAUGE)

If the MODE switch is pressed, 2 diodes are by-

passed. The remaining two diodes in the circuit

drop 1.2 Vdc (at pin B).

If the SET switch is pressed, 1 diode is bypassed.

The remaining three diodes in the circuit drop 1.8

Vdc (at pin B).

The gauge senses these voltages through pin 17

of the gauge connector, and interprets them as

signals that tell it which switch is activated. The

same is true for the UP/DOWN arrow switches,

iS switches and VTS switches on their respective

circuits.

If the command generated by the closure of a

switch concerns another module, a circuit within

the gauge will translate it to CAN protocol and

transmit it through the CAN bus. The applicable

module will react to the command, carry out the

function, and transmit the result back through the

CAN bus.

The information center will use the signals from

the switches and the transmitted information

from the other modules, convert them to an in-

dication, and cancel the command signal it sent

out once the function has been carried out.

Command signals from the MODE and SET

switches are used by the information center

only. VTS and iS switch commands are translate

and sent to the modules. The UP/DOWN arrow

switch commands are used by the gauge for cer-

tain functions and settings only. The UP/DOWN

button command signals will also be translated

and sent out through the CAN bus to be used by

the ECM for the CRUISE and SLOW SPEED func-

tions (increasing or decreasing speed when the

functions are active), and by the iBR for iBR gate

positioning in SLOW SPEED mode of operation.

NOTE: The above stated voltages vary slightly de-

pending on the actual voltage applied to the circuit

and the current flow through the diodes. When

using a Fluke 115 multimeter for testing in diode

test mode, the voltage and current applied by the

multimeter are lower than in circuit. The quality

of probe contact, the actual probes and leads, and

the precision of the meter calibration will all affect

the results, which will most likely be slightly lower

than nominal values stated.

MODE/SET and UP/DOWN Arrow

Buttons Test Using B.U.D.S.

1. Connect the watercraft to the latest B.U.D.S.

software. Refer to

COMMUNICATION TOOLS

AND B.U.D.S. SOFTWARE

2. Press the START/STOP button to energize the

electrical system.

NOTE: You will need to press the START button

every three minutes or the electrical system will

shut off.

3. Select the Read Data button.

4. Choose the Monitoring tab at the top of the

page.

5. At the bottom LH side of the monitoring page,

select the Cluster tab.
