Rev counter & clock not working

[AustinAR]

Hi kids and cats,

I brought an S16 with dodgey electrics, the rev counter half of the dials doesn't work, lights up but needles don't move ?ideas?
The clock is showing all the characters available, again is this an easy fix?
And finally the radio isn't working, everything lights up but doesn't seem to power up not fussed about the radio as I'll be putting my own HU in it at some point

Thanks in advance
