muddy4x4xfar Posted November 2, 2011 Share Posted November 2, 2011 hi all my discovery head light has been dull for some time now . theres nothing wrong with the unit itself or the earth cause that was my first thought so i changed that . i was wondering if there is a relay or somthing could be a bit dodgy if so does anyone know where it is , or does anyone have any other thoughts . the terminals are all ok as well by the way many thanks everyone chris Quote Link to comment Share on other sites More sharing options...
ChrisW70 Posted November 2, 2011 Share Posted November 2, 2011 There's no relays, feed comes off the battery, through a fusible link hidden in a 'cloth sleeve' along the wing to the switch on the column stalk and back out to the lights. Usual culprits are either the fusible link or the switch itself. Fusible link can corrode over time (look for green coating on the solder inside the cloth sleeve) or the switch can warm due to the current flowing (think this can be quite susceptible if you run on main beam for prolonged periods). A good modification to do is run fused supplies from local relays under the bonnet directly to the headlamps and use the existing wiring to switch the relays. This also reduces the volt drop on the circuit a little so you get a little bit more light output. Quote Link to comment Share on other sites More sharing options...
