If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

What is the Stator/Generator Output

Does anyone know what the generator wattage output is for the early 550 bikes ('77 to 79)?

Thanks
 
Don,
I could not find any official figure anywhere. Hopefully someone else has something.
My best guess would be 180 - 200 Watts. The bike has a 12AH battery, but not sure if this played a role at the time the 550 was built. Then again the OEM stator may differ compared to an aftermarket or a stator that fits off another type of bike. The 12 pole stator would put out less current than the 18 pole.
You may need to measure it, AC ammeter on one phase multiplied by 3 should give you a fair indication. Never tried it myself yet.
Hope this helps.

Power in a balanced three phase ac generator is P= 1.73 V I where V is voltage between any two phases and I is current coming out of one phase. So, if a typical suzuki stator has a V=14 volt and an I = 8 amp, then power is 194 watts. The 18 poles versions were probably a slight improvement over the 12 pole models, especially at low rpms.
Be careful measuring ac currents at high frequency, they can bite!
