RainyEye Posted June 25, 2009 Share Posted June 25, 2009 This is my 2nd Alumacraft and the first time I've encountered a problem of an inoperative gas gauge on the console panel. Before I start looking for the solution I thought I'd just ask for any suggestions anyone might have. Thanks! Quote Link to comment Share on other sites More sharing options...
Wish-I-Were-Fishn Posted June 25, 2009 Share Posted June 25, 2009 The gas gage on my 165CS is weird too. I never really know how much fuel is in the tank. Quote Link to comment Share on other sites More sharing options...
RainyEye Posted June 25, 2009 Author Share Posted June 25, 2009 Mine has always been hard to read because of the long and shallow tank, but now, it's dead, it just stays below empty, no matter what. Quote Link to comment Share on other sites More sharing options...

RainyEye Posted June 26, 2009 Author Share Posted June 26, 2009 Marine Man- this looks really helpful- thanks for this information! Quote Link to comment Share on other sites More sharing options...
RainyEye Posted June 27, 2009 Author Share Posted June 27, 2009 Marine man or anyone else: I followed the diagnostics down to the jumper wire, the fuel gauge didn't respond so I'm assuming it's a bad gauge. My question is, if I replace the guage does it need to be compatible with the sending unit or doesn't it matter? Thanks again!!! Quote Link to comment Share on other sites More sharing options...
boatfixer Posted June 27, 2009 Share Posted June 27, 2009 Gas guages are pretty standard as far as function, but try to find one that will match your existing guages. Did you verify that you have 12 volts going to the guage on the purple wire? did you verify you have a good ground? Quote Link to comment Share on other sites More sharing options...
jason007 Posted June 28, 2009 Share Posted June 28, 2009 I also have an issue and was wondering if there are any safety concerns to take into consideration when removing the sending unit from the tank with gas still in it? I am a little nervous about connecting and disconnecting a source of voltage on the sending unit to troubleshoot. Quote Link to comment Share on other sites More sharing options...
boatfixer Posted June 28, 2009 Share Posted June 28, 2009 A very ligitimate concern. When removing the sending unit itself from the tank, disconnect the battery and secure the cable leads. To toubleshoot the sender, you can run separate grounding wire to a safer location. Quote Link to comment Share on other sites More sharing options...
RainyEye Posted June 28, 2009 Author Share Posted June 28, 2009 Thanks for the info, I will check out the voltage and grounding before I purchase a fuel gauge. Quote Link to comment Share on other sites More sharing options...

RainyEye Posted July 5, 2009 Author Share Posted July 5, 2009 Problem solved- I opened up the dash from the console and tightened all wire connections on the back of the fuel gauge and it works! Thanks again for all the suggestions! Quote Link to comment Share on other sites More sharing options...
