This is a complete set of replacement fuses for a Datsun 240Z. This contains six 20A fuses and four 10A fuses. Fuses are a great place to start for resolving any electrical issues. Even if a fuse has not yet blown, corroded endings can cause a poor connection which can lead to general electrical issues. This complete replacement kit will allow you to replace all fuses with brand new equivalents or have a full set handy just in case.
