Tao Tao Quantum 150

[andyj812]

I got up early this morning to troubleshoot the horn and headlight. when I took the fairing of I found the horn on its bracket laying in the plastics inside the bottom of the scooter. In installed it an now the horn works but still no headlights. There in no wiring diagram in the owner's manual not even the generic one size fits all diagram that comes with other china bikes. I'm not if and where the headlight relay is, I checked all the wiring connections in the front. It looks like a royal pain to get the plastic off in the back because it appears for the most part to be on big piece.

Since I bought this scooter locally and even though I opted to put it together I believe I have a warranty. I am torn between dropping in off for them to fix it and fixing it myself and gaining more knowledge about how to fix it from the great people on this forum

Does the headlight not illuminate when the engine is running?

Does this scooter not have a spec plate showing which oil to use?



Regular 15W40 works fine for GY6 break-in, but change at around 50, 200, 500 miles to keep the suspended glitter flushed out. One option is to change to Delo at around 1,000 miles, which has a little more slick stuff (Zinc & Boron).

[QUOTE=tortoise;201462]Does the headlight not illuminate when the engine is running?

The headlight does not illuminate when the engine is running, not does the highbeam indicator light come on either. I checked all the connections on the front of the scooter and everything is good. I did not check the light switch with an ohm meter yet. All other lights: Tail, brake , running, and turn signal lights work fine. I suspect a loose connect at the headlight relay or the relay is bad if I can find it. I suspect it is somewhere on under the seat on the right side of the scooter. There is a lot of plastics to take off in order to view the wiring where I suspect it is.

It probably does have the spec plate. Last year for Christmas I bought the family 2 Tao Tao quad runners and Will 250 (I've since traded "Will" in for a CRF250L). "Will" used the Rotella since in didn't have the friction inhibitors and I somehow came to believe then That Rotella was best for the Quads. Since the scooter had the same engine as the Tao Tao 150d Utility I thought that Rotella would be the engine as well. Weld set me straight about the friction inhibitors. I'll look for the plate when I get home from work tonite

To be clear, I'm only offering another option. You should use the oil that you wish to use.

All of my bikes and quads drink Rotella 15W40, with the exception of my GY6 quad; it drinks 10W30 syn. My thinking is that since there is no clutch in a GY6, no firction modifiers are needed.

Just thinking out loud here: have you tested the headlight with a battery?

Thanks Weld for all the advice. I really appreciate it. I found time this morning to pull headlights out again and they are both burnt out. I checked voltage with engine running at headlight connector the headlight apparently run of ac because I was able to the get around 11 volts ac at idle. voltage goes up based on rpms. I ordered new headlights on amazon but will probably take a couple of week to come in.

[andyj812]

I got the new bulbs in and installed them. The scooter now has working headlights. When I installed the horn bracket (previous pictures), it appeared to have the voltage regulator on it as well. Although the lights are ran off ac voltage, I have read that not having the voltage regulator (dc) hooked up makes the whole electrical system do funny things. I am assuming and hoping that not having the regular hooked up caused the headlights burnt out.

Did that fix the high beam indicator?

The high beams and low beams work. I'm not sure if the high beam indicator is of ever was functional There is red light on the dash that is always l it and not marked what it isand what I assume is the high beam or just lights on indiacator (don't have option to turn headlights off) is faintly lit. These lights don't change with high beam or low beam switch position. The high beams are just a little brighter than the low beams. The headlight consist of 2 25/25 watt bulbs. Currently the headlights are working so I am happy, if I have to change them again I will look more closely at the indicator dash lights to determine how they are actually supposed to operate since I have to remove the headlight assembly to replace the bulbs. I ordered 10 bulbs on Amazon so I still have 8 spare.

[andyj812]

The one size fits all owner's manual does not have any documentation on the dash or indicator lights or how they function
