Can somone help me with fuel sending issues. I have 2 new 2017 G2's 300 and a Icon 7 " head unit. Dealer is telling me that the ICON head unit will not work with the analog senders that are installed on my 2002 fountain center console. Boat was brought to the dealer several times and kept for months and I still have no fuel readings. The dealer has then told me that they need to have custom NEMA fuel senders made to install in my tanks. This does not seem correct to me especaily after reading posts on this site. The dealer told me back in Jan that the senders should be done any day but still do not have the phantom custom NEMA senders. Now the service manager says he does not have answer for me that the owner of the dealership is working on it. At this point the dealer is just trying to get rid of me. Called BRP they tell me to call to call the dealer. So frustrated. Can anyone help point me in the right direction as to how I can get my analog fuel senders talking with my 7" Icon head unit. Thanks

Most senders are just a variable resistors to ground. The voltage fed to them for the most part is irrelivent . The control head (the G2) is just reading the resistant through current flow. However those Centroid senders are very unique, they have no moving parts and use Capacitance to determine the fuel level. This would mean that voltage is important for these gauges. I would find it odd that 5V is used to "power" those gauges on a G2, the control head is powered by the ignition voltage of 12 v. Would be kinda silly to step it down to 5 V. I suspect the output of those senders is not what the G2 is expecting. If you read the link below you will see the output is programmable and this may not be compatible with the G2. I suspect the reason it works with the exiting gauges in your boat is they are matched to those senders, not the 12 volts. If it were me I would leave it as it is, I would rather have thove analog gauges then hunting through menus on a panel display.
