1 A healthy battery is a happy battery. Keep yours in shape by plugging it into a charger - such as this Optimate - on a regular basis. If you have an alarm fitted it's best to plug the battery into the Optimate each night, providing you have mains power where the bike is parked
2 Keep the battery terminals and leads (shown here) corrosion-free. Clean them up with a wire brush, then coat with grease, Vaseline or Würth's battery terminal spray
3 Bulb bases are usually made of cheap metal that corrodes easily, impeding the flow of electrons. Give them a good scrub with wire wool, abrasive cloth or emery paper
4 Fuses are found in a fuse box, usually under the seat. A sticker should tell you which fuse serves which components. If you're lucky there'll be a spare or two, too
5 If broken wires and connectors want fixing you'll need this lot. It's good practice to practise stripping and crimping on scraps of old wire before starting on the real thing
6 First locate your broken wire, which can be easier said then done. Likely spots are around headstocks or under seats where badly-routed looms can get pinched
7 Cutters/crimpers like this are colour-coded - red for big connectors, blue for medium, yellow for small. Be sure only to strip back enough wire to fit the connector, no more
8 It may not be possible to fit the new connector back inside the main loom, so wrap it with insulating tape alongside instead. Make sure to tape up the cut in the loom too
9 If you're digging around in places like this (behind the headlight) to spray connector blocks, make sure the wiring is routed as it should be before putting it back together
10 Rear brake light switches are prone to corrosion and may need lubing or adjusting, but are often hard to get at. Worth checking, though, because you don't want your brake light on all the time. Rear indicator wiring an suffer from the elements too
