* Owner's Manual: The most likely place. Check the owner's manual's index or table of contents for a section on fuses or electrical diagrams.
* Inside the Fuse Box Cover: Sometimes, a simplified diagram is printed directly on the inside of the fuse box cover itself. The fuse box is usually located under the dashboard, often near the steering column or under the glove compartment.
* Mercedes-Benz Service Manual: A service manual for your specific year and model will have a very detailed fuse diagram, often with explanations of each fuse's purpose. You can find these online through various sources (often for a fee), at auto parts stores, or from specialty Mercedes-Benz repair shops.
* Online Resources: Websites like Mercedes-Benz forums (like the MBWorld forums) might have members who have scanned and shared their fuse box diagrams. However, always verify the accuracy of information found online. Searching for "1987 Mercedes 560 SEL fuse diagram" on Google or a similar search engine might also yield results.
If you cannot locate it in the owner's manual or on the fuse box cover, using a service manual is your best bet for a complete and accurate diagram. Remember to always disconnect the negative battery terminal before working on the fuse box.
