Lighting problems


Can anybody help, the rear lights, side lights and internal dash/gauge lights have all failed on my Fourtrak (2.8 TDX SE 1992). The headlights and mainbeam still function ok and the fuses appear to be intact. A friend has mentioned that it might be a relay?, but how do I check this out?
Any advice would be appreciated.

(Sorry posted a previous request for help under cars)

Don't know about a relay, but

Don't know about a relay, but you might want to stick a multi meter on the back of the mail light switch. Could be it's sending power to the headlight circut, but not the side light cicut.

Any veiws expresed in this thread by me are purely from my own experience, and (sometimes) falible memory. Hope my comments help, but please don't take them as gospel.
