In the event of an electromagnetic pulse (EMP) attack, you could lose access to things you take for granted like your washing machine or power tools. Before this happens, make plans to repair, rebuild, or re-purpose various items in your home so you don't struggle in a post-SHTF world.
Even if you survive a disaster relatively unscathed, you may need to restart your life by bugging out, especially if your home is destroyed after SHTF. If you're lucky, you may only need to make minor repairs to your home.
However, things won't be as easy, especially if stores close down. If this is the case, you may need to repair or re-purpose items around your property.
If you have a backup plan for your backup plans, you may have a survival stockpile that would cover most of your needs. But even then, you eventually need to repair something that is bound to break down.
To address these issues, you must learn how to repair your car and even your backup power systems. If you can't get in touch with repairmen, knowing how to do basic maintenance can prevent bigger problems in a post-SHTF world.
Make a list of important electrical, heating, mechanical, plumbing, and other systems in your property and the spare parts and tools that you need to repair them. Critical systems could get worn out or stop working, but if you're prepared, you'd have the spare parts you need to get them working again.
Don't get complacent if you already have a stockpile. After all, in a long-term SHTF event, you won't always get the exact parts that you need. Being familiar with your electrical system ensures that you can figure out a workaround and re-purpose similar items to what you originally need to do repairs.

To make repairs post-SHTF, you must have the following spare parts and manual tools on hand:
If you have the chance to bug in, you'd have access to stockpile with the various tools and supplies that you might need to repair and maintain your systems. But what if you have to bug out without most of your gear?
Since you can't just run to the store to buy everything you need, re-purposing items could be the answer to most of your problems. Learn how to scavenge for and recognize multipurpose items.
Learn as many prepping and survival skills as you can and know how to repair and re-purpose items to help you survive in a post-SHTF world.
