If the engine stops running, but the key
switch remains on, the unit will
automatically go to “Diagnostic” mode.
Diagnostic mode: Simple diagnostics can
be done with the key on, engine off. The
in
tent is to aid the service technician in
troubleshooting wiring or sensor problems.
It can also be used to verify a system when
th
ere is no engine on the boat.
In this mode, the following assumptions
are made:
1) The key switch is on.
2) There is no tachometer signal (the
engine is not running).
3) When the key switch is turned on, the
self-test will be performed as usual.
After the self test is completed, the
technician can ground any sensor input
lead. The system will immediately display
the fault condition associated with that
input. The audible alarm is not sounded in
this mode. In the event of a wiring error, it
would be possible for multiple inputs to be
grounded. In that case, the unit will display
th
e multiple messages.
