Hi all,
I've come across what i think is an electrical issue. My scooter is a TGB r50x 49cc, 2007. Two-stroke.
I know jack about scooter maintenance, but the symptoms I got the other day, were:
1) The scooter was running fine. In fact I had just hit 40+ mph on a local city street.
2) I stopped at a light. When I did, and she was idling, the lights started to dim, and the idle went below 1000 rpms, then the engine cut off.
3) It did not cut off super abruptly -- more like frittered away in rev power (with headlight and dash light dimming), then stumbled to a halt.
4) I was able to get it started up again with the ignition start, but only after a few tries. Before it succeeded, it would not quite turn over.
5) I was actually able to get the scooter going, and strangely enough was able to get the engine gas while going up to high 20s in speed. Mind you, the output was nowhere near as strong as it usually is, and I could tell I was almost kind lucky to get her going at all. But when I had to come to a stop at the light, I could already sense that the scooter wanted to call it quits. The lights dimming issue would appear, but also the throttle clearly wasn't getting juice to the engine somehow. When the scooter hit idle, it immediately wanted to die, and no amount of revving would help. She would just kind of cut out, but more like someone slowly falling into a crawl before lying down, not like someone falling flat on their face, if you follow… it was slightly more gradual, but the result was that she eventually died on me.
I have seen some great vids on here on how to use a Craftsman or other multimeter/voltmeter to test the battery and then test the stator.
I wanted to know if folks could tell me which one I should get (I am on a budget), and also which component I should check first. For example, maybe this is just a spark plug issue? Maybe a wire got dislodged from something or other when I went over a bumpy patch of road, maybe the battery needs a charge from a battery tender, and maybe either the stator or rectifier needs rewiring or replacement?
My knowledge of electronics is rudimentary, and when I see diagrams of how they work I start to feel ill lol. But I am a fairly quick study, so if anyone can tell me:
(1) which part I should test first,
(2) how to use the voltmeter,
(3) which one to buy on a budget, and
(4) where to buy locally since I don't want to wait for shipping..
Thank you!!
