Dead CX-5 battery and related problem

:
mazda cx 5 sport and mazda cx 7 sport
Hi there , after night was unable to start engine . Check Battery voltage shows only 4.8V. Charge battery overnight to 12.6V .Install back and... no signs of life at all .Only notice that speedometer and tachometer freezes at 11 a o'clock. Any ideas what happens ? p.s. gauges remain in same position even when battery removed.

I think I'd start with a known good battery before proceeding to anything else.
 
Maybe, you blew the fuse. In a 2018, the instrument cluster fuse is #41 located in the engine compartment fuse box. It is a 10 amp fuse in a 2018.
 
Problem solved! New battery , and new AT Shifter Switch . Thank all for helping out.
