Hello, it seems as if the battery at our CHRYSLER VOYAGER IV (RG, RS) 2.5 CRD has given up the mind. On the start there is only a “knock” in the battery area, otherwise nothing does. I will now after I have got a measuring device to check if the battery is really too weak or completely empty the battery is probably replace. Currently is an about 1 1/2 year old “Exide Excell EB741 680A built in. Eiin Mechanischer once at my previous Chrysler Grand Voyager ( BJ 96) said that I could not change the battery myself, because if you would interrupt the power supply, all electronics would be paralyzed and nothing would go on at all. You would always have to “bridge” this between time when switching, so that the power supply is not or only very short. Question, can this really be, and can I not get quite stinkingly the same battery and simply change it? Or do I really have to put the Voyager into a factory for this purpose. te?
