Electrical fault finding on a motorcycle can be challenging and if you're new to it the problems can seem daunting or insurmountable. However, with some care and patience it should be possible to navigate your way through the obvious faults. With a basic multi-meter, a notepad, seme time set aside and a modicum of common sense it should be possible to at least diagnose what the prcblems are. Buoyed up on the success of some elementary fault diagnosis repairs shouldn't be too irksome but if you're all at sea give Ferret a call. Oik test bike is now fully operational in the electrical department and is undoubtedly better wired than when it left the factory. As the man says, "Do it once, do it right!

As Ferret points out after we find this electrical mayhem, it's impossible to predict how long a wiring job or overhaul will take when you hit something like this. We'd actually factored in ar eight hour day to sort out the bike's electrics but we overran by a full four hours on the back of the issues discussed. Don't expect to be able to troubleshoot a bike's wiring in a couple of hours as it simply cannot be done.

Severed and partially melted - replacement is needed
