Question Sierra RS Saphire 4 x 4 2l 1990 DOHC Relays/Fuses

Hi all, first time on this site, hope someone can help. This cossie spends most of its life tucked up in garage (yes I know it's a crying shame) and usually only comes out for a run or two a year and for the MOT. I would hasten to add that it's not mine - I'm just researching for the old fella who keeps it going and isn't internet savvy.
Well anyway this year it has presented problems with electrical connections or perhaps relays on the lighting circuits.
As you will probably know there isn't much length of wiring under the fuse/relay board to enable the connections to the relays to be played with or probed. What I would like to find out is what each relay's function is so that I can isolate the probable problem areas. Any help would be much appreciated.

If talking about the fuse box relays(there are others!!), the legend is on the underside of the lid, just invest in a haynes manual for a std sierra of that age, cossie was based on ghia spec car loom wise.
Do you have any specific problems ?

Hi Tabetha, thanks for the info. I gather that there are only numbers on the underside of the lid with no info. Will try the Haynes manual Ghia spec as suggested.

What lights are you having problems with, it is unlikely to be a relay problem as it's only headlights etc that have them, do the side lights work?

Thanks for the interest Martin, it's the side lights that are causing the problems. Realise they're probably on a fuse but would like to get a handle on what does what.

Yes they do have a fuse the number is on the legend on the underside of the cover. The panel lights are protected by a different fuse this fuse also protects the number plate lights so these two should still work?

Thanks Martin, but there are only numbers on the back of the lid so will have to get the Haynes manual as suggested.

No problem, I can let you know what a relay does though if you give me the number?
