Tdci 2.4 electrical fault

My 110 was running fine pulled up outside shop for 5 minutes when I noticed the Rev counter go to 0, no dash lights only a dim ABS light.
driving home only in limp mode and no power windows
I have side lights but no main beam
I’ve looked at fuses under steering wheel and under seat I will look at earth straps tomorrow as it points to one broken as only dim abs light
It starts up ok but no dash lights
has anyone had this problem
Thanks

When lots of electrical things go wrong at once I usually suspect alternator. Did you find a bad earth?

All earth straps good even put jump lead to chassis engine and body as it’s starts without any problems starting to think it’s fuse box or wiring
