Nope, I'm not going anywhere. If I could I would go back to see the Pyramids being built. Or better yet...go back to 2014 to the Jonway plant and and make sure they build my bike right. As I was letting it warm up this morning, before going to work, I heard a rattle coming from what sounded like the air box. After getting back this afternoon, and working on the charging problem... AgAiN, I pulled the cover off.

 

Are you kidding me?  Broken into four pieces, along with a bunch of pieces of expandable foam(?). I went ahead and ordered a new one. But I did try to use some JB Weld, then realized it wasn't going to be ready by morning. So I pulled out my trusty glue gun and went at it.




I used a whole glue stick on it, then, put it back in. May not look all that pretty, but, it's better than new. This sucker isn't going anywhere.  

Well apparently my fix the other day on the charging didn't take. So I looked at it again today and used a pair of toothpicks to push the wires toward each other inside the connectors. I'll see how that works out in the morning when I can see what the lights are doing. I did receive a tracking number for the Caps and its looking like early next week for delivery.  

Thanks Guys,

Ok yelloscoot it's time to stop the electrical gremlin with the plugin system on the R/R toothpicks aren't going to cut it and you're going to be on the road with a dead battery or a burned up R/R

So let's go over what is wrong with the plug other than it's Chinese and how to fix the problem. First thing to do is watch this video from the video tech board on how to remove the pins one at a time from the male and female plugs, the plug is a little different in the video but the removal is the same on your plugs:

itistheride.boards.net/thread/8326/remove-single-wire-electrical-plug

As you can see the pin will pull out easily and by prying the little locking tab out you can put it back in easily and lock it back into place. Now I've seen two things on these pins that make the plugs lose good connections and this one may be your problem and it's simple the pin male or female may not be locked in good because it is not locked into the plug good and when you push the plugs together it is actually moving the one back while making a temporary connection when plugged in after a little riding it moves more and loses connection. Since you are using toothpicks this may be your case. Another thing is on the female plug I've seen the female part spread open and not make good connection with the male when it's plugged in.

By inspecting each pin you can see if there is a issue with the locking tab or a problem with the pin making it lose connection. You can also use a tiny eyeglasses screwdriver instead of a paper clip to remove the pins. I do one at a time and lock each pin back before I move to another one.

Now here is another problem I've found with Chinese plugins. Each wire has a locking pin connector for the plug and the Chinese are famous for not removing the wire rubber insulating at the end of the wire well sometimes and when they crimp the metal pin on the wire is actually not touching the metal properly and simply put it will pass no current. Here is a picture or a pin connector that is being installed properly:



You can clearly see how the wired is peeled enough so when the pin is crimped on there will be a quality connection to the wire. The red arrow is where the wire should be uncovered from the wire insulation but sometimes the Chinese will not peel the wire and just crimp the connector on and that will make a bad connection. The blue arrow is where the wire is crimped to just add support to the wire and generally is just crimped on the wire with the insulating rubber on too. If I find one that isn't making good connection like in the picture I simple take my pocket knife and peel the top insulation on the wire off right at the pin and solve it like this:



I know this takes a little of time but I soldier every single plug pin male and female alike in the electric charging systems on my scooters. One little spot of soldier and lock it back in place and never have a issue again. I soldier mine good connection or not.

Now if you get in this and find a complete mess don't worry, this is a great company that can sell you a complete new plugin kit that you can rebuild the entire system with:

Get the plastic off out of the way......again and fix this before it leaves you stranded out on the road.

Thanks for the links JR . This would be a good weekend project. I need to watch some videos on soldering. I have a little cheapo iron from H.F. which does pretty good (actually four of them), but keeping the tips clean has always been my problem. Maybe I need to get the sponge and copper cleaner thingamajig . (that's actually a real word...hmmm).  I did pick up their rolling stool with the tool tray. That did come in very handy during the PDI. Being able to scoot around and have my tools handy was a huge convenience. 

I checked the connector link you provided and have it bookmarked now. That's a good resource to have on hand. I also see the tape around the alligator clips, in the photo, when soldering to keep them from deforming. I hadn't thought of that, and, am guilty of that in the past. 

This should be enough to keep me busy for a while this weekend. I really want to get the bugs worked out of the electrical system. I can't help but feel I did something that caused the Gremlins to appear by working around so many wires and connectors. Even when being careful there's always a chance of pulling something loose. But, soldering all the connections and checking the integrity of each clip should resolve the issues.

Okay Leo, at least, think about it. You know how much fun you could have every weekend. I enjoy tinkering with the scoots. Gives me something to do. I'm learning something new with every little issue that comes up. There's just so many. 


That's most of them at the start of this adventure. Thankfully most of which have been taken care of. But others have come up since I started that list. But I enjoy the challenge and solving problems. That's one thing I like about Chinese scoots.

Come on Leo...think about it.

I've been trying to find some pics of the Red Star Scooter. Closest I've found is Mechanix Archives. I was born in '66, so, I wasn't quite reading yet.   This site does have some Harley Davidson articles and ads though. Also has some pretty interesting stuff as far back as the 1920's too.  

Well, the FluxCapacitors from Opt7, arrived today. From what I can see there is a capacitor and circuit board inside of each heat shrink sleeve 


JR

Thanks for the tip on keeping the tips clean. I have probably four rolls of the small gauge 60/40 solder. Yin has done pretty good,not 100%, the past two mornings after using the "toothpick trick". I checked the battery when I got home from work and it was at 12.85v and charging at 14.2v. But until I check and solder the charging system tomorrow, I wasn't going to put much trust in it, so I just parked it for the night. At least I have a good clue as to what connector to pay extra attention to now. (the one with all the yellow wires)  I also thought about picking up some 1" or 1 1/2" heat shrink to cover the connector like Opt7 used. Right now I have silicone over the clips.....

oldchopperguy , I hope you have a chance to give Minnie some TLC this weekend with the nice weather we have in the forecast. 

Loren, going hunting, for Gremlins.

As far as the radio goes.... these things are junk. I wish it wasn't even there. They look tacky, and now to get rid of it, I have to find something else to go in its place to cover the screw holes it will leave behind.

Just by the way the console is designed, no matter how it's mounted, it would look crooked.
I'll find something to go in its spot, eventually,I don't use it anyway. The new Hawk helmet came with a Kie Bluetooth intercom/phone/stereo kit.

The side stand is dangerous to Yin's well being. I very seldom use it, and when I do for only a couple minutes, I make sure there is a descent lean angle. My little Red bike is the same way. The girl I bought it from had it fall over from the wind. I won't leave it on the side stand for any reason, though, Red is very easy to set on the center stand.

JR

Okay, plastic is out of the way and things are going well. The first photo is the connector I feel was causing the charging problems. The spades look burned in the photo, but, I think they are mostly just discolored. I went ahead and used my Dremel with a wire brush attachment and they still look about the same. No rough spots, just, discolored (photo looks worse than actual appearance). Also maybe some pits, on the bottom edges, from arcing..

 
 

Now, after getting the "problem" connector with the yellow stator wires, I'm getting a reading of 14.8 to 15.3 volts while it's charging. This concerns me.  I don't want to overcharge the battery or take a chance of burning up the R/R.

Am I right to be concerned? With the motor off, the battery reads 12.8v, which sounds good to me. But, charging well over 14v volts, just seems too high.  At least it's charging. 

I still have a to do the connectors for the CDI and tail/brake lights tomorrow. I've done enough for the day.

 

Also,...what is the silver finned component next to the black finned R/R (right photo)?
The only thing that I've found even close is a diode on Scrappy Dogs website under common parts (towards the bottom of the page).

Any suggestions or comments would be appreciated.

Thanks Y'all,
Loren

Hello Guys,
     very interesting thread !!!, JR as always is a genius on scooters, congrats to yellowscoot for the new scoot, now :

   1) I also have a similar model rocketa MC-79-250, mine is skygo executive 250, I would like to install a givi windshield, this model D210ST Will fit my Scooter ?

       
 
2) The tires size on mine are 130/60/13" both, JR mentions that one could one size bigger?? what is this size ??

  change the oil just 4 times on 8 years is first time the I've hear that...amazing , I keep changing dino oil 20w50 every 1500km =).

Bye

Okay, The whole back end is soldered and sealed. After that little chore, the Opt7's had a little bit of flicker while idling, and dimming with the brake on while riding (still much better).

Tonight I soldered the connectors  and installed the capacitors that Opt7 sent. WoW...What a difference. No more flicker, strobeing or dimming. Just bright white light with a faint hint of blue (6000K). Awesome. The high beams will light up every reflective sign you can see.

The battery voltage is a nice 12.75 and charging is looking good at 14.75. The battery is staying cool, so, I'm not too worried anymore about over-charging. I would like to add a voltmeter, just for piece of mind, though.

I've also adjusted the shocks to the softest setting and that has helped even more to smooth out the ride. I had them set to the mid-point, before installing the Avons, to try and get a better ride from the Kendas. 

Leo, I have had my eye on the Opt7 Aura Motorcycle 10 pc. LED Kit. This might bring the charging down some. But I like the idea of having the white plastics that would "GLOW" from behind also. 

Now that Yin is charging properly the motor seems to have better acceleration. Or maybe that's just in my head. By my logic, LOL, better charging equals hotter spark.  I'll give Yin a few more days and see how things are going. I'm still dealing with the trust issue of the starter. I do not feel like pushing again. 

It's been a productive few days and I feel good about the way it's all coming together now. Now maybe I can use my time on Yin for fun and not tinkering.

Thanks Guys,
Loren
