Haven't had an issue as yet but am building an emergency kit for long trips.
Seems that there are only a few things that can leave you on the side of the road going nowhere that either you couldn't fix at the time cos you didn't know how, or have the bits.
A punctured tyre is the most obvious but not that common, but can be fixed easily enough with a plug kit.
Broken clutch or throttle cable. Either is a friend with a ute/ trailer, or a tow truck if you don't have the spares.
Failed ignition is the one that would be another ute/ trailer job or tow truck, but could be done on the run if you were prepared for it.
What I'm after is a wiring diagram showing what wires to cut/ join and switch.
Once I've got that I'll work out what bits I need and package them up.
Cheers, and thanks in advance.
