My 97 disco has an issue with no interior lights, headlights, or dash lights. The car starts but the dials on the gauges don't work either. I figured it was a fuse but was not sure. Thanks for any help you guys can provide.

 

You can download the factory set of shop manuals, called the RAVE. There is an electrical diagram set and they are pretty easy to follow. Could be fuse under hood (some have bolt in setup) or under dash, loose ground, etc. The 60 amp one under the hood is one place to start (MF3). Fuses can be blown, hairline cracked, loose, corroded, or have wire off on back of socket. If you have to, take each fuse out and inspect plus test for continuity with a meter or such.

Also - when working in fuse box with hood up always use something to hold down the hood alarm switch so immobilizer does not wake up confused.
