Wiring Diagram for 3.5 V8 twin carb 110 SW

Bought a 3.5v8 twin carb, but previous owner has had some dodgy wiring done to it.

My fuel gauge, temperature gauge and wipers all have suddenly stopped working?

I'm sure it's a connection or faulty wire (unless it's the fuel tank sensor unit).

Oh, I'm a newbie, any help will be much appreciated. Here to learn.

First check that there is no fuse or a broken common earth / power that feeds all the gauges..
