Acivat and Decov Voyager Board markers

Ola Friends of Menuals Demecanica I have problems with the brandodres of the board of a Grand Voyer they get and cool with the ignition engine

How can I solve the problem? Well I leave you

and I hope they are concession to me.

It depends on the markers that are, because they will defer the problem if it is the Check's battery oil marker, when they are like the handbrake, it may be lack of liquid if it is Power's notice can see a problem in the transmission box, also do not tell us if the truck fails that is to say some symptoms with the teaching light, that would be useful.
