how do i test the regualtor or stator i have a honda clone engine 2440. thae co says since we pull the battery terminal off ahd the engine shuts off it is a staor,would like to knoew how to check this.

Hey Ispoons -
Take a look ast some of the posts on charging systems, batterys not charging, etc. Theuy have some good info on the processesd.

Here is information on testing the stator I've collected from reading various posts and the Haynes scooter manual. Note that I know little of this first-hand so take all of the info with a big grain of salt. To start with, the stator is a coil, located under a cover attached to the right side of the engine (Right when facing forward on the scooter.) Here is a photo of the stator cover:  This is the coil underneath the cover:  Three yellow wires pop out of the upper part of the cover and go to the voltage regulator. There are a couple of other wires that are for ignition coil pickup, I think. There should be a connector for the three yellow wires some where between the stator and the regulator. The tests are as follows: - First check the coil resistance. This should be done with the scooter not running. Disconnect the connector and measure the resistance across each of the contact pairs, i.e., 1 and 2, 1 and 3, and 2 and 3. The resistance should be between 0.1 and 1 Ohm [Haynes manual]. I measured the resistance of a replacement stator Allnewsports sent me, and it was 0.9 Ohms across each leg.
- Second, check for a short to ground. Measure the resistance from each of the three contacts to ground. There should be infinite resistance; i.e., no connection.
- Now, with the scooter running, measure the voltage across all of the contacts pairs (again, 1 to 2, 1 to 3, 2 to 3). The reading should be about 60 Volts AC, give or take a bit. On my Viva, the readings were all about 12 Volts, i.e., way low. There may be a check of voltage to ground as well, but I'm not sure about this.
That's it as far as I know. But again, please take the above with a grain of salt; I'm simply repeating what others have posted or what I've read. Hopefully if there are any major errors, others more knowledgeable than me will correct them. Good luck, Gary PS: The Haynes Scooter tech book (available from Stan Jessup/Oregon Vintage) has a section on how to replace the stator. They rate the job as 'Fairly Difficult' (three wrenches out of five). I'm going to do mine in two weeks, next time I have a three day weekend. |
