Section 04 ENGINE MANAGEMENT (SDI)
Subsection 03 (COMPONENT INSPECTION, REPLACEMENT AND ADJUSTMENT)
Connect a switch (in OFF position) between a 12 V
battery positive post and the capacitor positive
post. Connect the battery negative post to the
capacitor negative post. Turn on the switch for 2
seconds. Disconnect the capacitor from the bat-
tery. Note battery voltage.
WARNING
Always respect the polarity when connecting
the capacitor.
Connect a switch (in OFF position) and a 300
5 W resistor to the capacitor. Turn on the switch
for 12 seconds ± 1 second of discharge.
Residual voltage after 12 seconds ± 1 second of
discharge must be above 5 volts.
Installation
Connect a 12 V test lamp to capacitor terminals
during a complete minute to discharge capacitor.
Make sure 30 A fuse is removed.
Install the capacitor.
Make sure to connect BLACK wire to negative ter-
minal and RED/WHITE to positive terminal.
WARNING
Always respect the polarity when connecting
the capacitor.
Install the 30 A fuse.
ENGINE START/RER SWITCH
VERIFICATION
Refer to STARTING SYSTEM and Rotax Electronic
Reverse (RER).
DESS POST VERIFICATION
If 2 short beeps are not heard when starting the
engine, refer to DIAGNOSTIC PROCEDURES.
The following continuity tests can also be per-
formed using an ohmmeter.
Disconnect DESS post wires.
Tether Cord Cap Removed
Connect test probes to post BLACK/GREEN and
BLACK/WHITE wires. Measure resistance, there
should be NO continuity (open circuit).
Connect one test probe to the WHITE/GREY wire
and the other test probe to the switch top ter-
minal. Measure resistance, it must be close to
0ohm.
Connect one test probe to the BLACK/GREEN
wire and the other test probe to the post ring.
Measure resistance, it must be close to 0 ohm.
Tether Cord Cap on DESS Post
Connect test probes to switch BLACK/GREEN
and BLACK/WHITE wires. Measure resistance, it
mustbecloseto0ohm.
