I have a taotao50cc scooter that has about 1,000,476 miles on it. I have done tons of upgrades to it- in all it's served me pretty well, I guess. Anyway- the damned thing isnt charging now and the only thing I think it could be is the diode rectifier or voltage regulator- whatever you want to call it. My conclusion is based on these facts... My bike is AC fired- meaning in order to charge the DC battery some sort of voltage rectification has to occur. My bike runs fine once jumped- the headlight burns bright- no problems. Battery voltage is a paltry 11.5v and BARELY turns the engine over and for only a second or two- not enough to start it without a jump. When the engine is cranked- I have no higher voltage at the battery. I tested with a multimeter- 11.5v KOEoff- 11.3v after I jumped it with the engine running. Normally I think I'm used to seeing maybe 13v with the engine running. Regardless- I tested stator output and am getting output from the stator. Is there anything else it could be? I just want to know before I run out and buy a part I dont need...

If you already tested the stator and it is putting out 40-100 ACv, and when revved the Charging wire from the R/R is not putting out then its your R/R.

Don't put yourself down no question is a stupid question if you don't know. That is how everyone learns and to answer your question Yes, R/R stands for Regulator/Rectifier.

Thanks- I'm going out tonight to go pick one up and will report back my success or lack thereof. =) Thanks for the help! |

How many pole stator do you have?

What year Tao Tao? Some of the older ones have a 4 wire stator. The newer ones have a 3-1-1 (5 wire) but a few have a 4-1 (5 wire). If you are getting less than 12v at the battery when its revving the stator is bad. The voltage should jump upwards of 14v. We've rarely seen an issue with the rectifier on Tao Tao that have charging issues. It's almost exclusively the stator.
