Thanks guys, I figured it out.
I took the harness from the switch to the loom out, and someone had connected the power feed wire to the headlight and parking light wires inside the harness.
Which means the lights come on as soon as the key is turned on. Since this scoot has two of the 35/35 watt bulbs, at $15 apiece, I would just as soon not have them running all the time, so I may put a switch in the circuit to turn them off during the day, and use the parking light to satisfy the law.
Thanks again, CZ

ok I reread your first post , check at the dimmer switch for ac and dcv . The old owner may have had a problem and altered the wiring . John Thanks for the reply. The right hand light switch, (off, park, headlight), does not change anything when I ohm the wires, except in the off position. There are six wires going in, and continuity between all of them in all positions, except in the off position, which disconnects the pink wire. Since the schematic referenced does show a pink wire in that switch, going to a resistor, I looked, but can not find one on this scoot. Also, since the switch is supposed to CONNECT the pink wire in the off position, and this one disconnects it, I am wondering if this model had a non standard wiring diagram. Thus my search for a model specific diagram. Another anomaly is that when the key is turned on, the lights come on, powered by the battery. This scoot does not seem to have been cobbled, with only 885 km on the clock, so I don't know if there have been any major changes to the wiring. It doesn't look like it, judging by the condition of the wiring loom and connector condition. A model specific diagram would answer a lot of questions. I e-mailed the manufacturer asking for a diagram for this model, but have not heard back after a week, so that is probably a dead end. Anyway, I will check for AC/DC at the switch, but am certain it is DC off of the battery. Thanks again, CZ |

Can we see the diagram ? John The diagram I am going off of is at .scootusa.com/wiring_diagram_for_ts50qt_with_4.htm" rel="nofollow" target="_blank"> .scootusa.com/wiring_diagram_for_ts50qt_with_4.htmThe headlight switch shows an off position, and when the switch is in that position, the current from the alternator coming in on the yellow line gets shunted through a 30W 7.5 ohm resistor. I assume that is to keep the voltage coming from the alternator down so that the rest of the components fed by yellow line do not get to much current due to high voltage.. However, the headlight switch on this scoot does not have an off position, which is why I am trying to find a wiring diagram for it. Was it set up that way from the factory, in 2004, to abide by the headlight on at all times rule of the DOT? Or is it a malfunction of the switch, in which case, where is the resistor on this scoot? That is why I am trying to find someone with this model of scooter. Any info would be appreciated. CZ |

I recently bought a 2004 Blacktiger TH50QT-3C, without an owners manual. Odd, huh?  Anyway, it looks like a Tank Sporty as far as the bodywork goes. I figured that the wiring would be close. However, I can not find a ballast resistor for either the choke or headlight circuit. The choke was cobbled into the yellow wire out of the alternator, and seems to work without a resistor. The headlight switch does not change anything, with the headlight being on at all times that the key is on, no matter what position the switch is in. Was that some sort of EPA safety arrangement back then? Does that negate the need for a resistor, since the resistor is only in circuit when the switch is in the off position, according to the generic wiring diagram for the Sporty Does anyone have a wiring diagram specifically for this Blacktiger model? Thanks for any thought or info. CZ |

Has anyone experimented with exhaust enhancements on the 50cc 139QMB engines? Not the "I'll buy whatever I can get" kind, but more the "what happens if I increase or decrease the head pipe diameter, and the length", and then the expansion chamber size and shape, the effect of megaphones, w/wo reverse cones, perforated baffles, etc.
Do they race 50cc scooters, and where would info for that be found?
Thanks, CZ
