is my battery or charging system broken? O.o By racerx125 (Read 2,318 times)

I just finished checking all conenctors and the harness itself and found nothing as for the R/R I am not sure how to check it using multimeter

Before my harness got fried my lighting was perfect and bright after my harness got burned and my motorcycle was left parked outside opened up for nature to play with it and when I finally fixed everything my lights where not as bright as before and my headlights are just bright enough to lights 1 meter in front of me on the darkest streets, but before replacing my R/R I will check it because my pockets are currently running low until next month

what did you fix after  it got fried ,the whole harness, I have not had to do that ,but I hear of doing a voltage drop test ,,someone else can chime in for this test ,but once its done you should know then move on to stator  if needed ,JR allyoop a wealth of knowledge ,try the private message if its urgent ,they will know

Yes Scot I fixed up my harness as I could not find a replacement harness so I replaced harness wires using wires from the harness
My headlights are not really important as I mostly ride on daylight but fixing my headlights would be a nice win

[scot]

you will get there ,in my state Newhamshire go figure still no helmet law,but working headlights to pass inspection,an some have the kinda light that flickers right at your eyes legal ,it a good thing for being seen,helmets I wear couse wind on my eyes makes them water ,.just don't like to much wind on my face .

Have you looked at the wiring diagram of this scooter in the tech section? If not get it and we'll go through it and get them going again.

I have tried looking for the wiring diagrams and haven't found anything for this motorcycle even finding parts is hard so I just go with the flow and what seems to be right.

Even at my humble level of knowledge, if your harness burned and you didn't COMPLETELY replace it, the chances of either a bad ground or a completely unintended bare-wire-because-of-melted-insulation ground somewhere seem pretty high.

As to testing the R/R, I'm just parroting what others have told me, but on mine the stator, the #1 producer of juice when engine is running, connects to the R/R via three yellow wires. Testing for **** A/C **** voltage across those three wires -- first A to B, then A to C, then B to C -- should produce pretty much the same voltage in all three cases. On mine, around 22v AC at idle, up in the 70v AC range at high revs. That is the "IN" side of the R/R. If those readings are bad, look at your stator and all the connections between it and the R.R.

Assuming all those are good, next question is what's coming OUT of the R/R. On mine, that involves three different-colored wires. ONE of those wires goes to a gizmo called the blocking diode, which determines how much voltage gets through to the battery for charging purposes. (Some folks, me included, replace that diode with a simple relay, same general purpose.) In any case, if you can find the R/R wire going INTO the blocking diode or relay, it will show some amount of DC voltage -- hopefully, something greater than 12v! Frankly I'm not sure what the other wires coming out of the R/R are for, JR or somebody will have to help there.

So anyhow, if the R/R is sending 12V or better to the diode/relay, look on the OUT side of the diode or relay and see if all that juice has made it that far. As I understand it the diode or relay are pretty simple gizmos, not likely to find a problem there, but if what comes out is more than a fraction of a volt different from what's coming in, time to look closer.

EVERYTHING I wrote above is based purely on my experience with my 2011 Roketa, so when you get under the plastic of your bike you may find things completely different. Number of wires, color of wires, etc. No guarantees, just passing on stuff I've picked up on this forum.

well ellpee the only wired that got burned was the positive cable for the harness but only where the key switch connects while the other cables did not get burned. the other 3 wires are colored red, green, and black.
I pretty much familiar with my motorcycle as I have been repairing it from bare frame I'm pretty good on disassembling and assembling anything that needs to be fixed just not much of an electrical person but I can still hold my own.

Does the regulator have a black wire ?
This is an important question !!!! Remember I sell parts that I test prior to placing in inventory . There is a quick test you can make to rule out a few things or circuits in the harness .

Yes 3 yellow and 3 other wires with colors red green and black, also something just came up it seems my battery only has 11 volts and motorcycle wont start it started fine in the morning and rode it for round 1 hour and now it has not enough charge to turn my engine over

[scot]

sounds like your not getting power back to the battery if the RR checks out good ,then its over to takeing off the crank cover ,an the stator ,,check everything make sure its clean ,an do what ellpee said ,pictures allways help for a bike we may not know as well as our own ,though we are all learning from one another ,if you have what I think you have its pretty easy to get to things everything is open ,its like a sportster ,

Sounds like me last spring; on any kind of an extended run, battery would go down, down, down until it hit 10v, at which point the CDI goes on strike and won't send a spark to the plug. And even in the 11v range the starter motor cranking speed suffered, thus hard starting. Replacing the R/R fixed that, although my charging system is still on the wimpy side and I did a lot of other minor things since then to limit voltage demand as much as possible. (LED bulbs, lower amp cooling fan, etc. -- see some of my other threads for gory details.)

So by all means check out that R/R as thoroughly as you can. I have a how-to PDF somewhere, I think, will attach it if I can find it.

Oops, it's over 1mb, attaching won't work. If you want to PM me your EMail address I can shoot it to you that way, or it's probably somewhere in the tech library here.

Scot it might look like a clone but only difference is only 5 gears and a 229cc engine and a single cylinder
