I've done some pretty questionable things in order to get home before
Not by choice, but rather out of necessity.
1. Patched a hole in a petrol tank by jamming a wet bar of soap over the hole to form a patch.
2. Packed a tire that slashed the sidewall badly with long grass to fill the void where air should go, drilled holes and cable tied the cut closed.
3. Braced a snapped leaf spring by cutting thick branches and lashing them to either side of the spring with ropes and straps to form a makeshift split.
4. Charged my friend's Land Cruiser battery in my Nissan Hardbody because his alternator died in the middle of the mountains. Started mine, then took battery out (engine still running) and swopped with his battery so my alternator charged the dead battery and he used my charged battery to start and drive home.
When you don't have any other options, you quickly make a plan to get home.
Electrical issues are my kryptonite though. If I can't see it physically doing work, I haven't got a clue how to fix it.
