Fuse panel box on top of the battery made by OEM VW. This panel holds the high amperage blade fuses. This fuse box can melt if any of the fuses are overloaded, most common with a faulty starter (that draws too much current) or a bad alternator voltage regulator.
Only for early style, two-piece battery boxes (up to 2001). Will not fit 2002+ models that use the one-piece battery box.
