The fact you said you rode it a little before the fuse blew makes me thing arcing at bad or loose connection, damage wire. May look for a spot where rubber insulation around wire is cut and may be arcing off metal somewhere. The diagram show battery + goes through main fuse to regulator and then ignition switch. I think I would start out checking wires and connection from battery to ignition and regulator.

Hi, Randy 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. The following is a list of usual suspects that will cause your bike not to turn over.
1. Ignition Switch is in the "OFF" position.
2. Ignition Switch is faulty.
3. Engine Run Switch in the "OFF" position.
4. Engine Run Switch is "FAULTY" or corroded.
5. 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.
6. Bank angle sensor needs a reset or is faulty.
7. FOB battery low or dead.
8. Faulty ignition switch.
9. Faulty starter button.
10. Faulty kickstand, clutch, neutral safety switch.
11. Security alarm needs a reset.
12. Starter relay, solenoid, starter motor or circuit wiring faulty.
13. Starter armature or field coils have failed.
14. Main fuse or circuit breaker may be blown or faulty.
15. Faulty ignition relay.
16. The electric starter is working but starter clutch has failed.
17. Check for engine trouble codes.

Hi, Leslie you need to repost your question under the Yamaha ATV engine number decoder category, not Motorcycles. Thanks, Gregg

Hi, Petglow and the usual suspects are:
1. Oil tank/system overfilled.
2. Faulty breather valve.
3. Engine breather hose bent, pinched, kinked, etc.
4. The air filter has too much "pre-oil".
5. Crankshaft seal failure allowing transmission fluid to migrate.
6. Blow by drain tube cracked/split or filled to capacity.

Hi, Alihomar23 yes it does for this scenario you will need your service manual that has all fastener torque specs and a wiring diagram on the back pages, parts fiche, and owners manual if you can not find the best tool you ever bought for your Yamaha, despair not, for a mere zero $0 you can download another one.

Hi, Mike I would love to help you with your engine or chassis noise but I just loaned my brand new pair of listening ears to your local dealer's chief technician so he could take your bike for a test ride and give you his professional opinion and estimate about your noise and repair cost.

Hi, Charles before testing any electrical component in the Charging System 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. Check 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 if necessary.
2. To check the regulator unplug it from the stator. Take a test light and clip it to the negative terminal of the battery and then touch first one pin and then the other on the plug that goes to the regulator. If you get even the slightest amount of light from the test light the regulator is toast.
To do this with a meter: black lead to battery ground, red lead to each pin on the plug, start with the voltage scale higher than 12vdc and move voltage scale down in steps for each pin. Any voltage is a bad regulator.
3. On the other part of the disconnected regulator plug. Set the multimeter for Ohms x1 scale and measure for resistance across the pins of the stator. You should read something around 0.1 to 0.2 ohms for a 32 amp system.
4. Then check for continuity between each pin on the plug and frame/engine ground. The meter needle should not move (infinite resistance)(digitals will show infinite resistance) if the meter needle does move (indicating continuity)(digitals will show some resistance), recheck very carefully. If the meter still shows continuity to ground the stator is shorted (bad).
5. Set the meter to read A/C volts higher than 30 volts (the scale setting for voltage should always be higher than the highest voltage you expect or you may fry the meter). Start the bike, and measure from one pin to the other on the plug (DO NOT cross the multimeter probes! - touch them to each other). You should read roughly 16-20 vac per 1,000 rpm.
6. If the battery was good under load test, if the stator is NOT shorted to ground, and the stator is putting out A/C voltage, then the regulator is bad (most likely even if passed step 2)
