Fuel Gauge connection for G2 icon.

I recently re powered with a G2 250 HO and my fuel gauge wouldn't read. Upon investigating I found the parameters were not set for fuel tank 1. I input the tank volume and set 2 points- 0% and 100%. I get erratic readings. Sometimes it says 100% or 0% or 35%.......etc. I checked the sending unit ( 10" reed contact type ) and it reads good. Does the sending circuit need a voltage supply or does the icon provide the voltage source?

Please further describe your fuel level setup & rigging.

 

Sounds as if you are using a WEMA style sender.  What is the fuel gauge you are attempting to interface with?  How is the sender wired into the system?

When you went through the calibration procedure, did you pause for about a minute between each entry? Sometimes the gauge due to its dampening system does not accept the input instantly.

I went to the dealer and they had to connect to the engine with the computer to calibrate the gauge. Also had to disconnect the fuel sending unit on the tank and get one out of their stock to calibrate the gauge then reconnect to the one in the tank before it would read.

Re: Fuel Gauge connection for G2 icon.

I repowered with a 225 G2 2 seasons ago. My digital icon gauge has not worked properly since the day I got it. I have brought the Boat back to the dealer 3 times to get it to work. The sender has been changed (brand new) the wording has been changed (brand new) and it has been recalibrated 3 times. When I leave the dealer it is working. The next time you start the motor it will read 0%, two hours later it will read 80% , a day later it will read 100%. I have not been able to get it to work since I had the motor installed and the dealer doesn’t have answers. Good luck, if you receive any info on your problem please let me know, maybe it will resolve my problem

9 times out of 10 it is the fuel sender or the wiring connections which are at fault. I know that doesn't help you at the moment but that is what most technicians experience. 

 

It is also advisable to run a separate ground wire, uninterrupted, from the sender to the control head ground for a secure connection.

 

The one thing that is important is when calibrating the unit, wait a minute or two for the readings to stabilize and record in the memory. In some cases connecting a battery charger to the electrical system making it run at 13V or above can make a difference during calibration.

 

Your dealer should double check everything and can call Evinrude dealer support services it they are having a problem getting the system to work.
