I’ve got a Windshield wiper delay kit (K2599). In the test, only accu power and no wiper motor, the kit works correct. When I install al the kabels than is the 15 sec delay only 3, 4 seconds and some times it whipes one time in these 4 seconds, some times two times or three. In the other settings it works also not correct. It looks like there are more signals in the time the whiper go over the screen. What kan be the solution for this problem? I already tried to switch the + and -
Probably caused by interference generated by the wiper motor. Try connecting a 4700µF cap in parallel with K2599 power supply connections as close as possible to K2599.
works perfect, thanks
