Good evening Foristii, I’m currently having a problem with the on-board electrics of my sprinter cdi211 from 2003. In regular irregular intervals the fuse No. 8 drives me crazy. It supplies the interior lighting (both front and back in the loading zone) , the cigarette lighter and in my case also the radio. I can’t yet understand what circumstances make the fuse burst, sometimes it lasts three days, sometimes all is good at night and the next Morg What have I done? First of all, I can tell you that I have installed a shelf for my tools, but cable calls have not been hit by my fittings, which I have already checked before. I dismantled, cleaned all the lamp bodies and provided me with new pears. I removed, cleaned and installed the door contacts. The cigarette lighter serves as a charging station for my phone. my question to the current freaks: can I, even if there is no electricity, measure somehow whether one of the current-conducting cables has a mass closure? As a carpenter and organ builder I have at least a basic understanding of (of) electricity, but the low-voltage range is, I often heard, like a book with seven seals. A rather daring thought drives me around, because somehow I have the feeling that if the Outside temperatures are high, as in the last two days, then I can almost expect the fuse to fly at some point. What do you think, how can I limit the error, what can I measure how, how can I proceed to get things on the edge? It greets Johannes from the north of Hesse
