Twin motors, Optimax 150s ser nos 1B222..... 2006 model year
Two Smartcraft tachs and one smartcraft speedo. all SC1000 models
A master reset was performed on all 3 guages. Port tach has 'lost comm' message, Starboard engine not found. ECU (555 style) was shipped out for testing and no trouble found. After much head scratching, I tried configuring port engine location in ECM as STARBOARD using Rinda Techmate terminal running latest firmware. The starboard tach and the speedo works correctly after master reset.
The port tach now establishes comm over Smartcraft CAN bus but I need the motor to be recognized as PORT. Right now this config looks like two separate single engine boats. I removed the Dual Engine harness so that Starboard does not see conflicting engine data. Speedo is connected to Starboard bus.
The wiring has individual harnesses each with terminating resistors and junction boxes at the helm. Note that the port tach did see the port engine which was programmed as port before the master reset. I can not tell if the port tach for whatever reason is only looking for a starboard motor or if the Techmate DDT has some sort of problem configuring the port engine as PORT. When I select that option, shut off and power back up the motor , the Techmate terminal does list location as PORT.
Any clues as to why the Smartcraft gauge only sees the motor when it is optioned as STARBOARD
It's driving me nuts
