Fuel gauge and rev counter stopped working

so ive just got my car back from the electrician, long Story short I fried all the wires in my car. Anyway he fixed it all and everything was working fine but now my rev counter and fuel gauge are acting up. 

They were working fine even after I fried the electrics they were still working but I got it back and now they don’t. any idea why? And is it something I can do myself because I don’t fancy being without my 5 for a week again . 

Assuming MK1?    Room? Fuse 10A in drivers footwell. If I remember correctly 2nd in top left
Kills Rev counter, oil pressure and indicators as well  NOT petrol gauge

You can get trip blade fuses so you can reset next time :wink:

Whilst faulting of course

 

ive checked the fuses none of them seem burn or bust?
