Guage wiring

[fish4life]

Okay guys we have been having trouble with our Yamaha Guages,there are a couple things we are not familiar with these digital guages,both turn on and get voltage,and trim shows,but the gas is odd it looks like it has 2 things that show gas and one says its almost full the Green tank with arrow above it?(not sure if its for gas)?and the actual gas meter just stays the same even when filled up it always stays at the bottom blinking,were not sure if its the float in the gas tank,but we fixed a trim problem in the throttle control box,and now the tachometer doesnt work,it turns on and the trim guage works but not the tack itself.wecan work on electrical to an extent but when it comes to 40 or 50 wires lol we kind of get lost.were not sure if theres a fault or what but some input would be nice,that speedo connection im holding was just free nothing connected to it,not sure what it was?

anybody have these guages so they could tell me what some of the bottom symbols mean?i understand oil and overheation but what about the tanks?

I have these gauges and trying to figure them out myself. On the tach make sure you are powering it with the starting battery. It will not work if its getting it power from another battery.

they are all getting powered by cranking battery,but the wiring is just such a mess,It did work at first then we messed around in the throttle control to get the front trim working and now the tack doesnt show its rpms anymore
