Water and electricity are not the best of friends and you've got to keep a few things in mind, especially now when the level of automotive electronics is on the rise with fuel injection and immobilisers appearing on cars in India.

• Check to see if all fuses are in order and always carry a few extra ones in the tool kit.
• All external wires, if any, (fog lamps, etc) should be properly insulated.
• Make sure the ignition system, CB points and ignition coil terminals are all cleaned properly.
• Make judicious use of a multi-purpose spray like WD40 or a similar water repellent on all critical joints and connections.
• Coat battery terminals with petroleum jelly, not grease, and check that the brackets holding the battery down are secure.
• Ensure that all lights, including the hazard warning, are in perfect working condition for it is imperative that you are seen by others, especially in heavy rain.
• Other than this, you should deal with most electrical problems as you would other electrical components.
