Hey everyone. I've got a problem with my Roketa 150cc not charging the battery the way it ought to. I have to pull my battery out every week or so and charge it up on my tender, because it dies every week or so. The battery is less than 6 months old. Here are some things I have done:
-Checked if voltage increases when I rev up the engine. It goes up, but it doesn't go up by more than like .5 volts or so, and never up to 13.
-Checked the regulator with my multimeter. It would increase power just a touch as well when I reved it up, but it wasn't significant.
-Changed out regulators from my Honda to my Roketa, and test it. Still not a big difference.
-My brake light is always on super bright. It doesn't dim when the brake lever is resting: It's just on bright, all the time.
-When I disconnect my brake light (For the test alone, NOT for riding on the road), the volts given out by the battery while turned on but not running (like when I turn the key) are around 12. When I have the light on, Its about 10 or so.
-I haven't checked the Stator because I don't have an impact wrench to pull off the big bolt.
Any Ideas?
Thanks!
-Kreider

Pull the battery from the scooter. Put it on a slow charge better with a charger with auto off. Check the voltage on the battery after you complete the charge tell us what it is. Then let it sit for 8 hours and recheck the voltage let us know ow what you get.
If the battery is bad it will cause all sorts of strange readings under different circumstances.
Keep in mind a battery could be new out of the box and defective. If you do not rule out the battery your not going to sort out a charging problem.
I hope this answer was not too long winded.

So I did what you said. When it was fully charged, it read 12.63 volts, and after a night of just sitting there, it read 12.53 volts. So I'm assuming the battery is fine.
I rechecked the battery, and now when I rev the engine up, there is absolutely no change in the voltage. However, the front lights get brighter, and so does the instrument panel. I'd imagine that this means that the stator is working and bringing power to the front, but when it is getting changed from AC to DC voltage, something happens and it doesn't repower the battery.
So, I'm going to change out the regulator when the new one comes in, and then I'm going to check the wiring and see if there is a wire loose. Hopefully this will be finished up by the end of the week!
Any other suggestions or insights, however, are greatly appreciated.

So I put in a new rectifier, and it still won't charge my battery very well. When I rev up the engine, the voltage increases by like .1 or .2 volts, but nothing in the 14's where it is supposed to be. My front lights didn't work this morning either. It's electrical, but I'm not sure where to look. Help?

4 pin regulator?
Did you add anything electrical or change anything electrical?

Just for info sake, What is the max volts a battery is allowed to drop after a fresh charge that brings it up to lets say 12.5 volts. How much can it drop in a day and still be cosidered good I wonder ? I charged mine up to said 12.5 and just sitting there for a day it droped to like 11.2-4 volts in a day.

I have seen freshly charged battery's read 13.3 then sit for a while and and they drop. if it is dropping below 12.4 not connected I would consider it bad. As soon as you turn things on and put any load on it you will be below 12. John johnathonkreider |

I checked the red wire from the r/r to the battery, it's fine. The ground looks okay, too. Is there anything that causes lights and front dash light to go out, along with not letting a battery charge, that is not the r/r?

I just checked the gaps on the coil of the stator to the flywheel in order to see if the gap was to large, and it was at 0.010", so the gaps are at the right place. I nee to double check the stator itself, but I've gotta get an impact wrench first. What else can I check? anything?

check it by resistance and output voltage. there have been some variations of wiring configurations. on the 4 pin regulators. I'll see if I can muster up some diagrams/pictures.

I'll check it out as soon as I get the chance, I've got a couple midterms coming up and my wife is pretty sick. I'll let yall know, though.

When my JCL MP250A (linhia powered) dash lights all went out it was that 20 amp fuse hidden in the starter solinoid connection plug. Then I found out my coil was bad too.

So I decided that I'm gonna replace the stator. I decided that after checking the connections and the continuity. I haven't yet gotten the flywheel bolt off (No impact wrench and limited time to rig up a system), so I'll be getting that done soon.
