Hey dear community! For some time now we have the problem at our company LT 35 of the 2nd generation that the turn signal on the left of the trailer does not work. Additional turn signal module has already been changed, without result! Oddly, however, that the light concerns when I break the module and close the contact switch by hand in this. So there is electricity from the part to the plug socket, so somewhere something has to be wrong from the turn signal lever to the module! Before I break everything up here and find me a wolf, where can I best start, measure or test anything else? Safeguards seem to be I.O! Which would be responsible for this?
