Hi, Anonymous there is no such thing as a weak spark even though dozens of riders will swear that's what they have and are dying to show you, the bottom line is either you have spark or don't have spark there is no in between.
You won't see a dirtbike spark really well, and people only look at it when they have a problem. It is designed to fire under extreme pressure (13:1 compression) and is very robust, but it is not a 1mm bright blue line jumping across a spark plug. It can be white and very hard to see. If you are confident you have weak or no spark prove it by holding the plug in your hand and stark kicking you will be in for a "SHOCKING" surprise!!!!!
60% of these bikes have a flooding issue and/or a fouled plug. 30% need valves adjusted and most of the remaining 10% are something simple in the electrics like a broken kill switch, bad earth on the battery or dead battery, wiring at the steering head damaged or blown fuse.

If you are gonna work on your own Harley, shell out the $60.00 for an H-D manual. They have a basic wiring diagram inside.

2006 Harley... | Answered Yesterday | 2,839 views


If the stator windings are good, the rotor magnets are good and the engine runs, there has to be an alternating current output from the stator and if the wiring is correct, the combined rectifier and regulator is working correctly and the battery healthy, it must charge.

I think you have missed something...
Do you have an alternating current output from the stator when it is disconnected?

Some older machines, Honda in particular, had a convoluted method of regulating the charging current using the headlamp switch and it took a lot of staring at the circuit diagram to check it through...

Hi, Rfonger and the usual suspects are:
1. Severely discharged or a damaged battery 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. Failed 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.
4. A failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, stator, magneto, ignition/electronic module.
7. Failed 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.
9. Faulty neutral, side stand or clutch lever safety switch.
10. Faulty or corroded kill switch.
11. Accelerator pump damaged or not working.
12. Water or dirt in the fuel system, carburetor or filter.
13. Restricted, blocked or kinked fuel line.
14. Fuel tank empty.
15. The gas cap is not venting properly or fuel tank venting system blocked, loosen the gas cap and go for a test ride.
16. A failed fuel pump, pressure regulator and or fuel injectors.
17. Vacuum line from the intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
18. Needle and seat stuck closed in the float bowl.
19. Petcock clogged or damaged.
20. Lean angle switch is faulty or needs adjustment.
21. Catastrophic engine failure, perform a compression test.

Hi, Tholliman73 before diagnosing your blown fuse issue, check the bottom of your seat, if its metal and comes in close proximity to the positive battery post you need to take the necessary steps to ensure there is no contact (electrical tape, thick rubber insulation, hammer a dent in the seat bottom, etc.) You are going to need a wiring diagram from your service manual, a test light, an ohmmeter and plenty of extra fuses.
If you turn on your ignition switch and immediately blow a fuse you have a hard/dead short and is usually easy to find. With a test light connected to the hot side of the blown fuse holder start stabbing the wire/s that leads away from the fuse holder and towards the ignition switch, you test light will illuminate validating the short. When the test light fails to illuminate you have passed the short and need to back up until the test light illuminates, then look in the immediate area for the short.
If you driving down the road for 30 minutes or 15 miles and blow a fuse you have soft/flying short and may take some time and patience to find.
If the main fuse/circuit breaker constantly blows/trips while riding you probably have a faulty battery terminal connection. Check battery terminals for damage or corrosion, check 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. Any other fuses that constantly keep blowing while riding are usually caused by a loose or corroded ground wire in the circuit, which means you have to check, inspect, test each and everyone with an ohm meter set on a low ohm scale 100 ohms or less . Simply touch one lead to the ground source and the other lead to the battery negative terminal, a reading of zero indicates a clean solid ground. Any reading or infinity indicates a poor ground and needs to be repaired. Poor or weak grounds require excessive additional amperage to complete the circuit which in turn blows the small amperage fuse.

Hi, Anonymous it should be noted that the reasons your FI light stays on constantly or flashes and your bike will or will not start and may turn over or may not and run great or sputter, 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 IE: adding accessories, electrical curiosity/adventures, laying the bike down/crashes, rain storms/bike washings just before FI light issues started can be significant hints/aids into tracking down the gremlin, also carry the appropriate jumper wire to access fault codes to reduce the risk of being stranded or towed. The newer the bike the more sensitive the ECM becomes and will not let the bike start when aftermarket accessories have been installed without being reprogrammed. That being said the usual suspects are:
1. Faulty Fuel Pump, fuse or system relay switch.
2. Battery starting to fail due to old age/damage, perform a load test.
3. A discharged battery, 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.
4. Faulty safety switches/sensors: run/off, ignition, clutch lever, neutral, side stand, tip over, fuel, and or their connections.
5. 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.
6. Installation of aftermarket accessories ie. exhaust systems, mufflers, air cleaners, fuel tuners, electrical component, etc.

Hi, Mark if you have a dash or instrument light that is out and you have confirmed that the bulb is good then you need to do some quick diagnostics all you need is a test light and a wiring diagram usually found in the back of your service or owners manual.
1. Make sure your battery is fully charged with "CLEAN" and "TIGHT" connections and the instrument light fuse is not blown.
2. Inspect the bulb socket for corrosion and clean as necessary, a spray can of electrical contact cleaner and compressed air works the best.
3. Confirm your test light is working properly by connecting one end to the battery negative post and touching battery positive post with the sharp probe, the test light should illuminate.
4. With the ignition turned on to confirm you have power to the bulb socket by connecting your test light to battery negative or ground and probe the center contact, the test light should illuminate if not you need to check the integrity of the switch or sending unit the light represents, if that is ok then you have a short in the wiring between the component and the light bulb, if all is ok proceed to the next step.
5. Confirm you have a good ground to the light bulb socket by connecting the test light to battery positive and probe any metal part of the socket housing, the test light should illuminate, if not you need to find the short and repair as necessary.
6. Inspect the integrity of the spring-loaded positive contact insulation tab by pushing against it with your test light to see if it goes down and springs back fully to it's operating position again contact cleaner and compressed air works best to restore proper function.
7. If your bike has a lot of mileage the vibration can cause bulbs to become loose in the socket by wearing down the soldered contact thus losing spring pressure from the tab and eventually stop making contact this can be fixed by replacing the bulb or putting a drop of solder on the worn-out end to ensure contact.
8. If all of your dash lights are out but are good then you most likely have a faulty connection to the dash wiring harness, inspect the connector for corroded, broken, or loose pins/sockets.

Hi, Ttatum2002 if your carburetor or exhaust is:
COUGHING is usually caused by an air leak in the intake system and will generally have the same telltale signs, a wet or damp build-up of oil/gas seepage at the intake manifold to the cylinder head or carburetor to intake manifold connection and in rare instances a worn throttle plate shaft and or seals.
POPPING on deceleration is usually caused by a lean fuel condition or an air leak in the exhaust system and is generally located where black carbon soot is seen as a flashing build-up from any joint connection. This condition can easily be remedied by removing and cleaning both joint pieces and reassembling with high temp silicone and torquing the exhaust clamp to the proper spec.
SPITTING is usually caused by a faulty accelerator pump and or nozzle, or the float bowl needle and seat leaking and overflowing through the main jet mixing well nozzle, or the air-fuel mixture screw is adjusted too lean.
BACKFIRING is usually caused by a sticky/tight intake valve or a timing issue, 180 degrees out or cam chain off 1or 2 teeth.
