the fuse is good.

Concentrate your search to the cables in the starter system then. If there's a short in most other components I'd think the fuse would blow when you turned the ignition on at least. Maybe try putting a multimeter on the power wires and see if there's any continuity with ground.

Did a little more inspection of the ignition system and found a couple pinched connections on the kill switch.  Also don't like the looks of the wiring on the ignition switch. I've read that some use four or three but not two. I ordered the origional switch or one close to it. I bent the Bracket back into position so I can mount the new switch back like it was. This switch locks the front fork which is nice. I'll need to dig up a schematic of the ignition system to figure out how to wire the switch in.   |

Well i found out the starter motor that was installed wasn't the current one. Its exactly the same as my other two scooters have. The splines on the gears are slightly different and need a starter motor with smaller splines. So it was binding and not turning. I stripped some parts off my spare motor and got it installed and working when I jump it from the battery. which is the best I can do until i get the relay replaced that got burnt up. Thanks to some help from Brent I got the ignition wired in correctly. So now i have spark and it cranks if I jump it. But it still doesn't start. The plug gets soaked just after a few cranks. Oh well. I'm happy with my progress for the day. Thanks again Brent..  |

Glad it worked! Won't fire if you hold the throttle wide open? Just thinking maybe it's flooded from the cranking before with no spark.

I did take the plug out and dry it off between attempts to start it. I didn't get that much of a chance to really mess with it much the wife was demanding attention. I'm going to work on it more tomorrow.

Well they way i figure it the first time the front wheel leaves the ground she will either hate it or love it. |

Got the new starter relay in today. Pushed the start button a few times and she fired right up. And nothings melted yet so coolz.

so I got all the lights working on my scooter finally after sorting out a few problems. I noticed my headlight comes on with they key and not after i kick it over. Plus the CDI is wired directly to the battery. So i am assuming it's a DC system? So if the battery is totally dead i can't kick start the bike to get it running? Also whats the best way make sure its charging the battery?

Yeah, that's DC. I've never owned a DC scoot. I always thought they don't start with a dead batt, but others have said theirs will.
Hook up a multimeter to the battery. Check VDC at rest. If it's charged up, hopefully it'll be reading 12.5V+. Start the scoot and watch the meter. The V should increase when it's running and get up to about 15V revved.

Here is the readers digest of how a CDI works
In all cases there is a magnet that passes a magnetic coil and induces a pulse in that coil which then is wired to the CDI and causes the small induced pulse to fire an electronic device (there are more than 1 type but this all happens inside the CDI) Which discharges the larger pulse stored in a capacitor. This larger output pulse is wired to the coil where the large pulse is able to make the coil function as a voltage increasing transformer thereby producing the very high voltage necessary to create a spark across the gap of the spark plug.
Now for the 2 main type of CDI used in the 49 cc scooter market, AC and DC Both function essentially the same. With the AC unit, alternating plus and minus varying voltages are used to charge the capacitor described in the paragraph above. The DC unit takes 12 volts more or less DC from the battery and that voltage is used to charge the capacitor described in the paragraph above.
Pros and Cons:
AC unit allows the engine to run without the need for a battery or charging system of any kind.
DC unit was created to allow higher RPM ranges due to the instantaneous availability of the Charging current. Where the AC one has lots of complex and difficult to explain things like coil flux density and residual decay etc.
an excerpt from scrappydog...doesn't sound like it will run or start without a battery....

Put all the body panels back on my scooter then realized i never installed my TTO tach. Went to take a video of my scooter running but apparently my phones needs a memory card first. Phones have memory cards now? Man I'm getting old...
