Slimothy: Forgive me if i'm wrong as this is from memory. If you look at the sonsole under the speedo, to the left you have a battery and oil pressure light. Symetrically to the right of the speedo (across from the battery and oil pressure) you should be able to make out two displays that dont light up. One is for the engine check light (on NATS fitted cars) and the other will be the low fuel light.
Even further to the right you should move onto the main beam warning light. Hope this helps.
BIG101: Big help there with the capacitor, any further info will be gratefully received, many thanks
