Recently, during a drive, we had an electrical fault. The switch I use to a security relay for the starter motor blew, meaning the starter would not turn over. This problem, once found, was easily solved by bridging the contacts of the switch with a screwdriver, allowing the starter to turn the engine, and engine to turn on.
Having replaced the switch, I began to think about other possible issues we might encounter. The fuse box, despite never having been the cause of an issue in all the time I've owned it, seemed a likely point of failure. The four glass fuses that the car uses to ensure nothing fries have long been overtaken by modern blade fuses meaning they're unlikely to be purchasable from a service station in the result of a blow.
This leaves me with four options: 1. Replace the fuse box with a modern upgrade with blade fuses 2. Somehow convert the glass fuses to blade fuses 3. Just make sure to carry spare fuses
The first one, mostly due to a desire to overhaul that particularly messy, dirty section of the car seemed to be the best choice.
