Trouble with indicators

[offroadrob]

The persoon i am working for has a land rover, not sure what model can find out is needed, and has found that when he breaks and indicates at the same time the right break light flashes and the right one does but only dim and not as bad. He works on a farm and the vehicle is used off road a lot and so can get very wet and muddy. Someone working on the farm told him that the engine may be short circuiting so we checked all the earth cables and cleaned all the muddy off wear the concectors touch the vehicle and chassis. Someone said the live might do this as well. I would be great full for any help advice on this topic,

Many thanks Rob

Hi Rob, try the earths for the rear lights. Has it got a tow bar? If it has,check the wiring at the trailer socket for corrosion etc.
