Bench testing Suzuki gauge for power up

[PatS4p]

IMG_3511.JPGIMG_3512.JPGIMG_3532.JPG I have 2 SMIS/C10 suzuki gauges, not sure of model, off of twin 2013 DF300AP's that were submerged. Can they be connected on bench to NMEA to see if they power up? Just want to find out if they are toast or not. Yamaha gauges have been good in the past with being under water, not sure of these.

Thanks

Yes, If you connect the C-10’s to a powered NMEA2000 network, they should power on and run thru a startup procedure.

Of course once they complete that they will show dashes where engine info should be if the network isn’t connected to an engine.

That's what I was afraid of. There is a yellow cased wire running to the backbone with red and black conductors. I applied 12V to the red(+) and black(-) wires with cable connected to backbone and connected the gauges, no joy. Could I be missing something else?

Thanks

C-10 only has one connection wire, its the cable that runs to the NMEA2000 backbone and takes both power and data. Plugs directly into a N2K T piece.

Anyway the later photos you posted show the gauges having started up as they would be expected to. So that looks good.

The interface cables have two white plugs at the engine end - one 4 pin, the other is 2 pin. For AP 300’s they should have come with a twin engine adapter cable and from memory they have orange connectors. The 4 pin interface plug connects to the adapter cable that is then connected to the gauge harness for the relevant engine behind the dash.

Usually on later engines you dont need to connect the 2 pin plug because trim data comes via the main 4 pin, but if it doesnt then it gets connected to the 2 pin plug that would normally be used for trim gauge.

I assume (always dangerous) that the same gauges interfaces were previously used on these engines? If so, you could be lucky and it all works without needing to be set up/configured again. But anyway if it does, that is pretty easy, come back and ask if not sure and I can run you thru how to do that. One thing to note is that at the engine end, the main harness from engine ecu to dash needs to be connected to the SDS plug. It should already be connected up there.

The most common method of powering the N2K network for this system is by connecting the + wire to a spare bullet connector in the gauge harness and the - simply to the neg busbar behind the dash. Doing it this way, the network is powered on and off with the engine key. And it follows that the C-10s will turn on and off when the engine key is turned on and off, and will go thru their startup procedure every time. including that fuel reset thing.

If you want to avoid that, you can power the network from a separate switch that you can turn on and off as you choose. All that means is that while that switch is turned on, the C-10’s will also be on, and when the engines are turned off, they will show dashes the same as your bench test. This arrangement also has the advantage of meaning that if you have other devices networked that need to communicate all the time, they can do so without needing the engine key to be turned to the on position.

This is the adapter cable to connect the interface cables to the engine harness on AP models.
