Hello

Let me start by saying I'm sorry if I posted in the wrong area. I have a 25' Rhib with a 2014 200HO G1.. the boat came with a pair of I Command Gauges.. recently one of them failed .. its 5 years old..

I never liked the gauges and took it as a reason to upgrade to ICON Pro .. I was told they are plug and play on a nema 2000 network which ran ICommand gauges. I followed the instructions but when I power the boat the gauges dont come on .. in the instruction it shows analog wires and power wires.. this is embarrassing but do I need separate power wire with these gauges when I didnt need one with the I Command ?
My assumption was that the power came through the nema 2000 network as it did with the ICommand gauges ..

Also the I Command both plugged into the network .. this new system leaves one network open .. is that okay ?

This level of tech is new to me and the dealer hasnt got time in the summer for instant service so I am attempting it alone .. the plug and play got my confidence up

Thanks
Rick

The ICON Pro Series RPM gauge must be supplied with its own 12-Volt DC power,

Only very low power consumption devices can operate entirely on NMEA-2000 network power.

ICON Pro Series gauges all use stepper motors to operate their dial pointer gauges, and all are powered by the RPM gauge. This should be clearly described in the installation guide.

Any NMEA-2000 device with a power cord will need that power connected—that is why there is a power cord on the device.

The network is a NMEA network; it is not a “nema” network.

Recommended practices for unterminated NMEA-2000 network device nodes remain the same no matter what brand or model devices are in use. Leaving one unterminated network device node is not recommended but usually is not fatal to network operation.

There is no special forum for this topic on this website. Posts about this topic are scattered everywhere in various forums, often making finding information on this topic difficult,.

I appreciate your reply. The stepper motor explanation is logical. The power wire for the tachometer has an actual connector, as the dealer didnt suggest I also purchase the other end, I dont have one. It's a purple wire and a ground so rather than wait for another shipment i suppose I could just clip the connector off. The articles you have written are far superior to the supplied instructions .. thank you

I concur: cut off the connector and use your own wiring method to deliver power. Although I do recognize that in adding the connector Evinrude made rigging faster for installers in some situations.

The power leads for ICON Pro Series RPM gauges only recently were delivered with a connector. Evinrude shows a Y-cable power-splitter assembly in their newer rigging guides and provides accessory power on a mating connector, more or less assuming that the E-TEC engine wiring harness from the ignition key switch will be the source of power for the ICON Pro RPM gauge.

That you found my technical writing to be informative is gratifying. Thanks for your kind remarks.

Evinrude didnt supply the other half of connector. I dont mind cutting but does this power wire not need a fuse ? If so what size ?


Thanks again for replying ..

In distribution of electrical power, all branch circuits at a power distribution center should be fused. There is no basis to think that a branch circuit feeding power to a NMEA-2000 network would be exempt from over-current protection.

A branch circuit for NMEA network power should be fused at 3-Amperes. This advice is explicitly given in the article I recommended to you as a primer on NMEA-2000 networks.

Fuses or other over-current protection are usually placed close to source of power.

If there are others devices connected to the same branch circuit, you will have to install a second fuse in the NMEA circuit.

I was given the impression hat upgrading gauges was a plug n play event. It's not.

I dont have much experience to be adding fuses to the power line .. I appreciate your assistance but I think I will call for a tech ..

In canada boating season is short so waiting for a mechanic is a disappointment.

RickF - Adding a fuse to a 12V circuit is "almost" child's play.  Get a fuse holder, 2 Heat shrink, adhesive lined butt connectors, cut and crimp the two cut power wire ends into each, and then a heat gun or even a hair dryer can seal those connections against water intrusion.  Add the appropriate fuse such as 3 amp as JimH suggests, and you're back on the water.

I wouldn't give up the season as easily!  If you can cut and crimp, the extra application of a bit of heat to seal out any water shouldn't be much of a problem.  Even if you're not comfortable adding the heat, adding some "Liquid Electrical Tape" around the splices should help.

The IconPro tach is supposed to connect to the violet (purple key on power) wire in the engine harness, this wire is already fuse protected with the engine fuse.

The engine ignition key ACCESSORY circuit (violet conductor) is fused under the engine cowling, where the circuit begins, as Rick mentions. If you plan to use that circuit for the NMEA network power—a good approach—you can add a 3-Ampere fuse to the NMEA circuit (best design) or just rely on the fuse under the engine cowling (10-Ampere) and go boating.

I'm not wiring friendly but a buddy came over and did the fuse and power for me.. I could certainly do it now that I've seen it .. gauges came on but I am getting NO DATA on both.. probably normal.. I will read the entire programming manual .. it looks well written ..

I would first do the gauge SETUP procedure in the Manual.  Then maybe hook up to a hose, and try the gauges while running at idle.  Power "On" does activate the gauges, so a bit of progress there!

The NO DATA suggests a problem within the NMEA 2K network or the connections to the gauges themselves.  Didn't you have an "open end" on the network?  Might not be the solution, but weird things do happen with that.

Looking forward to hearing of Success!

Phil

Here is what happened.. the tachometer self tested .. I chose language.. did the rest if the set up and changed fuel to 48 gallons .. then his save and the screen flashed and now says no data ..

I re attached the data cable .. turned it on and off and it simply displays no data on both gauges .. could it be a faulty fuel sensing unit ? I ask because just before the last gauges failed the odd time it would read zero fuel.. I would power off and back on and it would read the correct percentage of fuel .. would the sending unit crash the whole gauge set hp ? I can ask the dealer to come out.. the boat is a sealegs and sits in the parking pad by the house .. it cant go to the dealer .. no trailer .. so the dealer is usually 3 or 4 weeks to come out..
