It`s a confusing one, it seems as if your system is designed so that DC voltage from the battery powers sidelights, horn etc. and the headlight would be powered by AC through the yellow wire. However as there is no voltage through the yellow wire that seems odd. The pink wire to the ballast resistor won`t have voltage coming from it, only to it. it`s there to take away unregulated voltage from the yellow stator wire and dissipate it in the form of heat into the atmosphere. The unregulated voltage would otherwise cause a few blown bulbs. If you are happy with your current DC set up and everything is working, then as long as you have at least 13.5-14.5 volts at the battery when the scoot is running, then it shouldn`t necessarily go flat with proper use.

I always covered my bikes up overnight if they were outdoors, mainly to keep the damp from getting to the electrics and of course to prevent corrosion. Even in summer there is a certain amount of damp both at night and early mornings. It also a form of deterrent from thieves as they can`t see what is under the cover and are normally too lazy to find out.

If as JR states, the yellow is a 'helper' feed from the stator which will give voltage when the engine is running. Then the pink could be connected to a ballast resistor somewhere, this would take away excess voltage fed by the yellow wire. It`s quite a while since I came across a similar circuit so could be wrong, but I seem to recall the pink having voltage feed with the engine running and the 3 position switch in the off position.

Yes the switches are a bit flimsy. You could pull the plug off the back of the 3 position switch and find which one of those wires is the feed from the ignition. The pare a short piece of wire at both ends, pop one end into the live feed terminal of the plug, and then pop the other end of the wire into each terminal on the plug in turn. You should be able to find out which wire feeds which lights. Once you`ve located the wire which goes to the hi/lo switch, you can work from there.

Do the side lights work just by turning the ignition on or do you need the engine running ? I`m presuming the on off switch is a 3 position off/side/head, if so then there should be 3 wires going to it, one feed to the switch, one feed from switch to sidelight, one feed from switch to hi/lo switch. When you run a feed from the battery are you putting that to the hi/lo switch or direct to the headlight bulb ?

You shouldn`t need to as the red wire won`t be live until the starter button is pressed. However as a general rule of thumb in instances where you are not sure, then just disconnect the earth lead from the battery, that way there is no possibility of a circuit being made. With any live lead on a scoot there isn`t much possibility of getting a big shock, the main worry is touching the lead accidentally to the engine/frame and shorting the circuit which would burn wires or blow a fuse.

I suspect the battery is shorting the system out, have you got a mate`s battery you could borrow just to check ?

It could be running lean, have a look here on how to adjust your mixture link

The exhaust - there's a metal pipe coming out of the engine that goes to the muffler. It's solid. There's too much stuff in the way to tell how that pipe is connected, and I'd never be able to get a tool on a bolt, even if I could see it. I'm not going to take the whole moped apart. I went out to see if I could just take the muffler off, but it's welded to that metal pipe. The muffler/downpipe is one piece, pop some cushions on the floor on left hand side of the scoot and tip it onto the cushions, should give you a better view of the front of the exhaust. The downpipe is held on by two nuts to the cylinder. The muffler should be held onto the engine with two bolts. This is all that holds it on, five minutes to remove at most.

Does the engine rev freely when the bike is on it`s centre stand ? I`d consider taking the airbox off completely and having a look down into the carb to make sure there are no shards stuck in there. Then take it up the road, it should still run faster than 5mph even with the airbox off. If still no joy then remove the exhaust and give it another run to see if that makes a difference. Accidents are weird things and can dislodge the most unusual items which don`t even warrant a second thought normally. The secret is to physically eliminate certain items to try and find the problem, it`s no use saying "I don`t see how...." as you have to get your hands dirty to get things sorted.

Most of our fleet bikes count in km, the main dial of the speedo is also in km, with mph in small figures around the inside. Nothing unusual in it. The only ones on our fleet which have the odometer in miles are the ones with digital dashes which you can flick between miles and kilometres at the touch of a button.

I`m with Alley, even though you say the battery is new and fully charged it sounds like it`s got a bad cell. We had loads of Jet Euro 50`s on our fleet and they used to eat batteries and regulators for a pastime. Part of the problem was the lights working on a DC circuit, in that they came on with the ignition switch without the motor running. There was no separate on/off switch for the lights, just a hi/lo switch. The standard battery is a ridiculously small capacity 12v3ah. Get the battery drop tested, and/or try another battery from a mates scoot which you know is good. Once you have a battery in there, connect a multimeter to the battery terminals to make sure the regulator is working. You should get a reading of around 13.2 to 14.7 volts depending on whether the scoot is idling or revving.

We had a similar problem on a Sym Jet 4, turned out to be a loose pin on one of the multiplugs behind the front panel. Took us a few goes to fix it as the damn fault kept recurring when we thought it was sorted. Here`s a pic with the location of the regulator/rectifier, the plastic box under the seat is I suspect the CDI. The reg/rec should look like this or very similar (note the fins for cooling) This is what the cdi will look like (or very similar)

All our fleet are Syms, they are a lot more expensive than the Chinese scoots but they are, by and large, a lot better quality, We have had reservations about the paint thickness on the grab rails, wheels and exhausts unfortunately, which seems to wear off very quickly. We have been offered the possibility of running a dealership, which the boss is weighing up at the moment. Good to see a review of the 300, I`m also looking forward to having a look at the new 600cc scoot they are offering.

Does the engine on your bike need to run to make the lights work ? Trace the wire which feeds your dip or hi beam up to the hi/lo switch. On that switch will be 3 wires, one each to feed the hi and lo beams, the other will be a feed from your on/off light switch. Check the feed on that wire at the hi/lo switch, if there is voltage then the switch could be faulty. If there is no voltage then you need to trace the wire back to the on/off switch. Here you will find another 3 wires, one to feed the side light, one to feed the hi/lo switch, the other will be a feed from your stator or battery depending whether it`s an AC (lights work only with engine running) or DC system (fed from battery). Check that this wire has voltage.
