Zeg mij maar een s na in jou taal ut
vertaal het eens.

seeing it only shows up for a second the sensor harnsess might have a loose or dirty connection although im not sure how that hyster would be set up
im imagining it has an ev200 system like the 1 i have in my area

a few english corrections (as im sure its not your everyday language) just to help
cable not cabel
brush not bruch
"1 second end is gone." should be "1 second and is gone."
"some wone their they can help" should be "someone there that can help" there, their, and they're can be very tricky to use correctly when english is a second language
im part dutch too but i can speak maybe 3 words lol

speaking of good english translations
"have a good luck"
