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, Ken for this scenario you will need your service manual, parts fiche, and owners manual if you can't find the best tool you ever bought for your Can-Am, despair not, for a mere $15 you can download another one.

Thanks for the details, they do help. Is there a way you can disconnect different electrical circuits from the battery? Like Disconnect the lights, horn, or other components then start adding them back until you find the circuit or group of wires that causes the short. Because it seems you have a short somewhere, or something really putting a load on that 30 Amp fuse. So I'd break the circuits down to smaller pieces so that when you reconnect the lights, or starter, or whatever....that the fuse pops and you know the circuit causing the issue. You may have to open engine components like a magneto to isolate the circuits. But it shouldn't cost you anything except time.

Hi, Surat and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
3. 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. Loose connection at ignition coil or plug between ignition sensor and CDI box.
5. Spark plug cables in bad condition, shorting / leaking, spark plug cable connections loose, check for spark leakage in the dark.
6. Faulty ignition coil, pick up coil, trigger coil or CDI box testing needs to be checked with an ohmmeter at 70 degrees Fahrenheit
7. Faulty safety switches clutch, kickstand, neutral, off/on etc.
8. Faulty ignition switch.

Could be bad fuse.
Bad ignition switch
Wire connector
Bad or broke wire/connector
Start by checking fuses. Then trace wires to see if they're burned out. Replace ignition switch

The TaoTao 50cc mopeds I have seen advertised are gas powered requiring an electric starter battery. There are TaoTao scooters which are electric. The one at this link has a rechargeable battery. The last link below may be of interest as well.

There are a set of 4 steel springs that press the clutch plates and a heavy pin that pushes the plates apart. You need to engage the clutch to check. If the clutch will not disengage then it is the pin. If the clutch slips while riding, it's probably the springs.

Hey Mike, I did a generic search for electric bicycle batteries, then searched specifically for Timco electric bike batteries. $150 seems the price-point break near the bottom of the new batteries on up into $300+ ranges (and sometimes much more). It may be based on your specific needs and requirements tailored to your particular model of electric bike (which was not stated in your question).

Pay particular attention to your battery voltage and ampere per hour needs as determined by your bike's requirements, or simply look it up in your manual (if available). You can find some cheaper batteries (used and new) on ebay, but if looking for a good quality new battery with a warranty I would probably search Amazon for a new replacement battery. Batteries in bikes last about two years before they start to lose their abilities to hold a full-charge. Best of luck to you & happy biking! ~Andy K.

It should long as you got the right chain and the same size sprocket on the new motor as the one on your back tire. Also make sure the motor Wil mount proper .

Cylinder not firing. Remove plug and verify spark. Also verify fuel to cylinder.

Unable to test. Must verify other components in system, if they are all in spec. Than it's down to cdi.

Make sure plates are seated and not loose when assembled. There should be no slack in plates.
