20 Most Recent 2010 Yamaha WR250R Questions & Answers


Hi, Sergey it should be noted that the reasons your check engine light or CEL stays on constantly or flashes and your bike will or will not start and may turnover or not, these conditions will vary from bike to bike depending on the year, make, and model and you should always refer to your owners/service manual for proper diagnostic procedures. It should also be noted that any type of prior work done to the bike or an abnormal event occurrence such as adding accessories, electrical curiosity or adventures, laying the bike down or crashes, stolen and cut ignition wires, rainstorms or bike washings just before CEL light issues started can be significant hints or aids into tracking down the gremlin, also keep in mind that your CEL comes to life if anything, and I do mean anything isn't 100% with the ECM such as parameter spikes. This means that you could be staring at a major repair, or something very minor, like your speedometer sensor, is contaminated and needs to be cleaned.
And the usual suspects are:
1. Severely discharged or a damaged battery check the terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary, you should 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 charging system.
3. Faulty system sensor some models have up to 40 sensors
4. Faulty safety switches: run/off, ignition, clutch lever, neutral, side stand, tip over, fuel, and or their connections.
5. The engine got wet in places where it doesn't like to get wet.
6. Faulty ignition circuit spark plugs, coils, cables etc.
7. Broken wire or worn insulation exposing wire to a ground situation especially inside wire harness at tight bends around fairing brackets, under dash panels, under fuel tanks over cylinder heads etc. Many harnesses are open on the ends that will allow water to enter and accumulate at v-bends.
Dielectric grease and contact cleaner are your best friends for wire/cable/harness connectors, look for corroded, broken, or loose pins/sockets. Run speedometer diagnostics and check for generated fault codes.

put some fuel system cleaner in it

Yamaha... | Answered on May 20, 2019


Bruce,

Most problems as you describe are due to the connections on the battery or starter being loose, corroded or dirty. Clean your connectors ( the big wire ones) at your battery, starter relay, starter, and ground (just follow the big wires from your battery terminals) and I'm sure you will find one or more connections along the way that are corroded or loose. Make sure the connections are tight, clean and free from corrosion and your timberwolf will crank over just fine.

Hi, Er the vast majority of service, parts fiche, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee of $15 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available and some were never printed in English. The Indian and Philippine markets are usually in E-book format only, for these rare occasions I shall look on eBay and find the cheapest one available. Most of the manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have. If there is no $ sign after the manual link it is free to download.

Hi, Anonymous before testing any electrical component in the Starting Circuit it is "IMPERATIVE" that you have a fully charged battery of 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 type batteries fall into this scenario more so than lead-acid batteries.
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Engine Run Switch is "FAULTY" or corroded.
4. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter.
5. Bank angle sensor needs a reset or is faulty.
6. FOB battery low or dead.
7. Faulty ignition switch.
8. Faulty starter button.
9. Faulty kickstand, clutch, neutral safety switch.
10. Security alarm needs a reset.
11. Starter relay, solenoid, starter motor or circuit wiring faulty.
12. Starter armature or field coils have failed.
13. Main fuse or circuit breaker may be blown or faulty.
14. Faulty ignition relay.
15. The electric starter is working but starter clutch has failed.

Hi, Mark the answer to this question is way above my pay grade for this situation, I would call or visit my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry.
