20 Most Recent 2002 Yamaha YZF-R6 Questions & Answers


Hi, Graeme and the usual suspects are:
1. Severely discharged or a damaged battery must have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
2. Faulty alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.

6. Faulty ignition coil, ignition/electronic module.
7. Faulty CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.

Hi, Selfds a motorcycle starter relay is an electronic mechanical switch that has a small coil winding around a piece of metal that requires low amperage and thin wires to be activated. When you turn on your ignition switch power 12 volts is sent to the relay coil which in turn becomes a magnetic contact point that pulls a spring-loaded contact point to itself completing an electrical circuit that allows more amperage necessary to be accessed by the starter solenoid which in turn acts in the same way as the relay but on a larger scale with its stronger heavier contacts making available the necessary amperage to turn the starter motor. If your battery has low voltage it, in turn, makes the magnetic contact point weak in trying to pull its counterpart to make a connection. These relays are usually encased in a plastic housing that may or may not be sealed depending on the quality of the product. When activated they will produce a small amount of heat to their metal components which in turn can create the perfect environment for condensation to form depending on weather conditions and how careless you may be with a water hose or sprayer while washing your bike. After a period of time, several months to several years depending on circumstances this condensation is the start button for electrolysis and the slow build up of corrosion which ends by preventing the magnetic contacts in making a solid connection and alerts you to this situation with the customary greeting "CLICK". The relay is inexpensive and needs to be replaced however in a pinch they can be forcibly opened cleaned and resealed with silicone. In a nutshell, motorcycle starter relays take in low amperage and send out higher amperage when activated and for curious minds, the voltage remains constant at whatever your battery reads at the time, this is why a fully charged battery 12.5 volts or better is the best insurance on preventing starter motor problems and increases the longevity of all the starter circuit components.
