Halogen headlight taillight/brake light turn signals odo/speedo and horn. Here are the problems… Above about 6000 RPM the ignition will intermittently cut out. It doesn’t do it all the time. The higher the RPM the more it tends to cut out. Reducing RPM brings the lights back to bright. Above about 6000 RPM the lights start to dim intermittently. The higher the RPM the dimmer they get to where the lights almost go out. The engine runs fine if the RPM is reduced. The tachometer records some very high RPMS when the system starts to act up. Max RPM recorded is 19999 which is totally unreasonable. I am looking for some assistance in troubleshooting my electrical system and how to isolate the problem(s).,Start by disconnecting the cables from the generator coils and start up your engine. Problem still there? Do this to find out if your problems stems from the power side or the ignition side. If bike now runs fine, I'd look at the voltage regulator. Have you checked that all your connectors are ok? A grounding problem with a somewhat loose connector would be vibration sensitive, hence the problems at higher rpm. Is your stator plate securely fastened? Is your engine grounded to chassis? There might be a loose fastening in one of you engine mounts. Reply With Quote,,,

Can I replace the stock 45 amp charging system on my 2002 FLHTCUI with a 50 amp high output system like the newer models have?


Yes you can, no problem. The battery will (theorically) recharge a little faster but the main advantage would be if you use more electricity with gismos like high intensity bulbs or heating vest. However you should not use a charger more power than 20% higher than the original as then your abttery could overheat or even overcharge.

Hope this help !

Add lightbar to 2006 suzuki c90 stock warning?


As long as the lightbar's power is less than 50 Watts and you secure it with it's own seperate fuse (5Amps for 50 Watts) I believe you don't have electrical issues. Use seperate lines directly from the battery and use a switch to turn it on only when your engine is running. Of course you may have warranty issues with your dealer if you install it.

My '98 900 SS ie misses and backfires at low revs, around 60 k/p/h and slower. Thanks.


The engine misses the firing as there is a faulty electrical issue or a fuel mismatch on the settings.
Now if this happens ONLY on the lower RPM,But there is very good performance at higher RPM then it is possible that the timing is set or is offset. It will best to have the engine tuned with the correct timing using the right equipment. Check the engine firing at low RPM Make sure there is no gasket leak on the manifold/exhaust that would change the firing.

I want to remove the baffels from stock 06 Sportster mufflers


not a good idea unless you upgrade the air cleaner to a high flow or screaming eagle...bike is tuned to run with restricted pipes..if you change one you need to change the other..with the 06 you could also need a download or fuel management system..

Electrical? Carbs? Battery?


Hi, Jeannette in order to check out any main electrical system, you have to start with a fully charged battery 12.5 volts or better, and be able to pass a load test if necessary. "WARNING" never plug or unplug any electrical connector with the engine running !!!
1. 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.
2. Check the voltage drop at the battery when you hit the starter button, anything below 9 volts you might have a faulty battery.
3. Check voltage at the battery with the bike running at 3,600 RPM should be 14.3 to 14.7 volts. If you are not getting these numbers, you might have a faulty voltage regulator.
4. Make sure voltage regulator is "GROUNDED" and functioning properly, watch the video below on how to test a voltage regulator.
5. Unplug the connector to the alternator and hook your multimeter leads to the alternator (pin/socket selection does not matter) set the multimeter to AC volts, at an idle the multimeter should read 16 to 20 volts AC. at 2,000 RPM 32 to 40 AC volts, 3,000 RPM 48 to 60 AC volts. If you are not getting these numbers, you may have a faulty rotor, follow step 6
6. Set the multimeter to OHM'S, connect one lead to the alternator (any pin/socket) and the other to a ground, the multimeter should read infinity. Connect both leads to the alternator multimeter should read 0.1 to 0.2 OHM'S. If you are not getting these numbers, you have a bad stator.
7. Check all wiring in the charging circuit for worn or chaffed spots and all wiring connectors in the circuit for corroded, broken, or loose pins/sockets, which is the # 1 offender.

2006 Bonneville America electrical failure


To start with, your battery was probably already low. You have to be at about 4000 rpm for the charging system to kick in and put out 14v or so. So if you just sit and idle, you will eventually run the battery down. If it is already low, you may have run it down below where there are enough amps to start it again. I know my 2002 BA started having what appears to be charging or regulating problems and the batteries won't stay charged. Try charging the battery with a good trickle charger to begin with. Then, when it is fully charged, run the bike and see if the charging system is keeping things up.

I have an 06 XL 1200 that just started choking out


This could be a variety of issue's from over choking, to bad fuel. Make sure your not leaving the choke on to long, as this can foul the plugs. Bad fuel could cause this, as water or other contaminents get into the float bowl and don't affect the enrichment ports due to fuel bypassing the float bowl. This would lead to the bike running worse as the enrichment knob is pushed back in. Last but not lease, could also be an electrical related issue due to the bike warming up and causing a short or open as stuff expands. I would change your plugs, then drain the float bowl into a clear glass jar to examine contents. if fuel and spark seems ok, you will have to look at electrical. plug wires, crank shaft position sensor, coil. It may take someone with the tools to test these components in order to diagnose the issue. If you see that the tach (if you have one) or lights in your display's flicker, it could also be battery related. loose ground. Many possibilities.

You have a slightly gummed up carb. I would get a can of carb. cleaner that you add to the fuel and hope that running that through the carb in a couple of tanks of gas will solve your problem.
