With the charger unplugged, if you get the LED's in the fuel gauge, then check the fuse. If the fuel gauge is not lighting up, then there is either a contact problem between the battery and inverter, or there is a bad component in the battery. If you do not normally remove the battery (or did not between when it did and did not work) then I suspect a fault in the battery controller itself.
Other than the fuse, there is not really anything that can be done without sending the unit in for service.
Thank YOU for replying , I checked the fuse and it looks just fine , I will later on today buy a fuse and try to change , and nope I had never removed the battery till last night in order to see if that will fix the problem , the gauge is not lighting up @ all , all I get is the "power" Led amber than green for less than a second , and that is it . . . Is this common ??
And there is really nothing else for me to do , right ?? just sent it to you guys , I still puzzled on how could this have happen I mean I take extra care of my stuff , no bangs , no drops , nothing how can this happen ?? how long does it take for me to receive the unit back if I send it to you guys to get serviced it is still under warranty
