Same problem i have seen others have on here with the charging system not working and battery draining within an hour while in use.

i have replaced the regulator twice and the stator once and am still having problems.

i keep buying new batteries to try and track down the problem further but they keep going dead and then wont accept a charge afterwards.

i did once use a booster pack to jump start the quad and am wondering if that potentially cooked other electrical components perhaps?

google is failing me at this point and this forum seems to be the most knowledgeable that i have found.

help please

side note: i also only have a regular vehicle type battery charger, i assumed it was fine to charge the quad battery with but am now wondering if that is my problem for why the batteries wont hold a charge and wont charge again after being drained?

 

If you charge the battery slowly and as soon as it goes flat, don't wait a day or two with it pancaked and don't leave on charge for too long (3 to 4hrs) the battery should last at least a year. Most common reason for batteries to fail, if you are doing the above, is overcharging. This heats the battery up and destroys it. Reason for overcharging is a faulty regulator. The first thing to do is put on a known good battery, start engine and check voltage across battery, rev engine and see what happens. Voltage should stay between 13v and 14.5v fluctuating a bit, if it goes over 15v it will cook the battery. If it stays about 13v or under and doesn't drop when you switch engine off, it isn't charging. Trouble with some small machines is they don't have a regulator, just a rectifier, and problems with translation from Chinese means the two are often confused by sellers of aftermarket parts. Regulators have a rectifier inside, to change stator output from AC to DC, but they also regulate voltage to under 14.5v. Bikes with a rectifier only, have a deliberately feeble stator, theoretically incapable of much more than 14v output. If you combine a high output stator with a rectifier, you get overcharging.

If it isn't charging, check you are getting power from battery to regulator, using a high wattage 12v test lamp, not a multimeter.

 

Thanks for the info. My charger shuts off automatically when it gets to a full charge, not sure how long after so maybe that has been the problem?

I ordered a new battery but it is a week away. Am i able to use a different battery for testing purposes while its running?

Your also correct, it is actually only a rectifier not a regulator.

The stator also had two white wires coming off the harness when i went to replace it and the plug had a white and a yellow. I hooked them up one way with no luck then switched them around and still had no success. Could that have damaged my stator?

 

If the battery you are using for the tests is good it will be OK, but if it isn't it will throw the readings out. The stators for small quads come in a variety of types, simple two wires from coils to rectifier, or two wires from separate coils which are earthed, or full three wire, three phase types. As I wrote above, you may have bought a high output stator and coupled it to a rectifier, this will boil batteries. I doubt if connecting it wrongly would hurt the stator though it may not do the rectifier any good if one stator was the earthed coil type and the other wasn't.

 

Ok thanks, thats kind of the conclusion im coming too. Are there other rectifier/regulators that i could swap mine out for that would work to reduce the current coming out of my stator or do i need to find a different stator?

 

Not sure if it was Tao Tao but about 2019 one maker sent a load of new bikes out with this problem and owners had a hard time finding a regulator, as all the eBay Chinese replacement four wire "regulators" they tried, turned out to be rectifiers and overcharged. Honda Recons do have a rectifier for a two wire stator but I guess they will be expensive.
