Round Command Link fuel gauge just dissappeared

[behmer]

My Command link fuel indicator on the right side of the round command link system just dissappeared. When I initially start up the self test shows all 8 bars light up but then those 8 bars dissappear and I cannot tell how much fuel I have. I looked at the wiring briefly just to verify that they did not come loose some where, but so far I cannot locate any visible issues that just pop out. The command link is hooked up to my 2009 Yamaha HPDI VMAX series II 250 HP.

Thanks for any help on this matter

test continuity from the white wire on the back of the guage to the fuel sender and test the sender and the sender ground.
