Stator Problem?

[meloabreuu]

When I took my scoot to the shop the last time to fix multiple issues, they said the solution to my starting problems was a new battery, and sure enough, the electric starter was fine. Eventually,the electric start wouldn't work after my very very short ride to work, but I could kick start it, I would take the long way home, and all was fine. Then my electric starter stopped working completely, and my gauges wouldn't light up until I kickstarred It and the engine was running. This morning, there wasn't even enough juice for a kick start, I had to hook it up to an electric jump. I let it idle for a half hour after I got to work, and it kickstarted fine, but I obviously need to resolve this issue.

I believe the stator is the equivalent to an alternator in a car, and it sure seems like that is the problem.

Any ideas on a troubleshooting procedure? I'm pretty sure I have none of the measuring instruments I'm probably going to need, so I you could be specific with those that'd be great, thanks in advance.

Get a cheap Volt meter and check the voltage reading on the battery (DC) with the engine running. It should read between 12.8 and 13.5 at idle and go up to 14+ when revving the engine. Anything else means that your battery isn't charging right which points to a bad connection at the stator plug or a bad stator or a bad regulator. Sometimes a reg and stator are both bad.

Could be a bad ground wire. (broken, burnt)

By the way you describe it, you may be dealing with a DC CDI system there. Make sure you get the correct stator for your scoot!

I just wanted to add that when I hooked it up to the charger, I still had to kickstart it. Could this be an indication that it's a bad voltage regulator?

The regulator should have no effect when the engine isn't running. If it goes bad it can cause the battery not to charge so you can't start the scoot if it is a DC CDI.

I have a question. Just because I was the cheapest possibility, I bought a new voltage regulator and just installed it. If that was the problem, how long will it take for the battery to recharge itself and start working properly again?

Scooter charging system is very weak. Your best bet is to charge the battery with a battery charger and then run it in the scoot. I have seen a fairly dead battery charged up enough to e-start the scoot again within a 20 minute ride, but it really depends just how dead the battery is.
