Thanks Stevo2. No, the tool I do not have you 're right, but meter will be used. I am retired electrical engineer so meter I can handle well. You see, my problem started by dead front wipers. Motor is ok and I discovered, that wiper relais does not get ground from multifunction switch and so it does not clik on. I opened the switch and repaired main + contact, which was opened. However, the problem is still there. So I brought artificial ground to the relais and by switch and 2 wires I am able at least to wipe my windshield. While checking the relais, another bad news: my headlights (low and high beam) do not work either. The same problem - ground absent on the negative terminals of relais' solenoids. If I bring the ground, lights go on. That is, why i suspect open common ground wire somewhere or inside, or arround the main fuse terminal. I am in Canada and it is cold here, my van is in the driveway and so before the spring comes, I do not feel like to work on it and I am collecting informations from nice guys like you. Meanwhile, numbers of my inside bypass - switches is increasing and soon I will have to label them to know which one operates what (just kidding). Listen, I realy thank you for your imput. I do appreciate it. Thanks Jan.
