Default Battery top fuse box burn...

I've heard some of the most ridiculous explanations as to why a fuse block would melt here in this thread.... Our cooling fans have nothing to do with keeping the fuse block, alternator leads or anything else electrical cool. The fuse block melts and burns because there is an unregulated amount of current coming from the alternator into that fuse block. Our alternators put out about 14 volts when working correctly. If the voltage regulator malfunctions that voltage can climb much higher and cause an over loaded circuit, etc. Normal voltage coming from the alternator should be about 13.5 volts. In our cars and most all others these days the alternator has a built in regulator that can be replaced. It is an all in one carbon brushes and regulator unit that lives inside the alternator... Start checking voltages with any multi-meter and you will be able to find where that voltage spike is coming from and fix it. Just because a garage says they work on German cars doesn't mean that they can fix them! Check your local VW dealers service department and see if they have any kind of recall concerning possible fires and melted fuse blocks that apparently have cursed our cars. This could be construed as a safety issue... Good Luck, JK
