Thanks for everyone's help. Problem solved. The part that had originally gone bad was the stator. I tested it with an (old) analog meter, that's all I had. I put a new one in and when the engine revved up the voltage would drop. A friend came by and he had a new digital VTOM. When we connected his meter it was showing it was charging. I guess my meter is either broken or not compatible with scooter electronics

Does it sound like I have a short in the yellow wire/circuit?

Great, thx for the Pics.
The first Pic is yes --- exactly
The second Pic is a NO, I disconnected the plug (separated it)from the R/R and took the (2nd) measurement at the disconnected plug/harness.
Hope I am not speaking a foreign here, lol
thx again...

thanks, I re-did my response, less confusing now.

Frist, Thank you for getting back to me.
What I am saying is when I check the voltage at the R/R, harness connected; then I disconnect the plug from the R/R and measure the voltage at the plug/harness, I get the exact same voltages. Both measurements were taken with the harness was connected to the Stator, engine is at idle.
Hope that helps....
According to the wire diagram it shows wires tapping into the yellow wire.
At the pig tail of the Stator the voltage is 18vac on the yellow and 23vac on the white wire, at idle.
thanks again

Thank you for everyone's input. I think, with some insight from this forum, I think I may have narrowed down the problem to a clue.
The voltages at the R/R is the same whether the R/R is connected or disconnected.
The R/R plug, measured at the harness: RED=12.5 vdc / WHITE=10.5 vac /YELLOW=6.25 vac, at idle, same exact measurement when connected to R/R.
Again, the measurements are the same whether connected or disconnected, at the R/R. This was done with the Stator pig-tail connected to the harness, and engine idling.
Battery 12.5. Under load test - 11.7
Stator @ pigtail yellow to white - 0 ohms / yellow to green - 1 ohm / white to green - 1.1 ohms. It's a new Stator.
Resistance at R/R plug, harness is connected to Stator - yellow to white-INF. / yellow to green 1.8 ohms / white to green - INF
Stator voltage at pig tail @ idle - yellow 18 vac / white 23 vac - voltage increases as revs go up, around 30vac.
Ohms measured at R/R plug, disconnected from R/R - yellow to white .7 ohms / white to green .7 ohms / yellow to green .6 ohms. Stator is connected.
Something is happening to the voltage from the stator to the R/R
hope this info helps -- thanks in advance |

Thank you for that information. It would not be the first time that I bought a new, defective part.
I will check from the beginning, do a load test on the new battery, and go from there. And, record the numbers. BTW, no alarm...

Thank you for your reply. I will take a look again hand get the exact voltages, but one, the yellow was at or a little over 15v, and the white wire moved the volt-ohm meter a lot more, maybe double, around 30v. The old stator had only 5v on one wire. I just installed a new stator and a new R/R, and I still seem to have the same problem. I then reinstalled the original R/R, same problem. The battery is 4 months old, and seem to hold a full charge. I will load test just to be sure..

Hello everyone: I have a Roketa 2007 150cc. The charging system is not working. The Battery was replaced 4 months ago, with a Yasua brandI checked for charging at the battery and it shows around 13v @ idle. When I revved up the engine the volt meter drops below 12 volts. So I checked the white and yellow leg of the stator with one lead on the stator wire and the other lead to ground. One leg only produced 5 volts, so I replaced the regulator. I know, I know, I replaced the wrong part. Rechecked the voltage at the battery and still had the same problem,of course, dummy me. Then I installed a new stator, and now either makes over 15 volts. I reconnected everything and checked the voltage at the battery and it still has the same exact problem, the more I rev it, the more the voltage drops. With a new battery, R/R, and stator, I thought everything would be ok, it's not. Can I get some wisdom this matter. Thank you in advance. |
