WARNING NO STARBOARD ENGINE (a)
Informs you that the Instrument does not see the starboard engine computer. Usually indicates
that no data is being transferred from the engine’s computer to the gauge. (Check wiring, also
make sure both terminator resistors are installed in the bus). Make sure both ECM’s are not
configured for port location using a DDT or Quicksilver Diagnostic Tool.
WARNING MULTIPLE STARBOARD ENGINE (b)
Informs you that the instruments are recognizing multiple engines as starboard.
In multiple engine applications, each engine must first be assigned a position (starboard, port,
starboard2 or port2) with a Quicksilver Diagnostic Tool before the system will function properly.
If you have a dual engine application, you must first program the port engine with a Quicksilver
Diagnostic Tool.
