    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. 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...

  • Returning Visitors

    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.

stator problems

I was wanting to advise everyone of a problem i had with mine. wasn`t charging enough to keep the battery up. got the manual out and READ IT! it said to disconnect the 3 wires coming from the stator and crank the engine and at 5k you should get around 75v. AC between any 2 of the wires. i did this and found that i only had power coming from only 2 combinations but not the third even though i read the same ohms which ever way i connected it. the stator was bad and i replaced it. i`m saying this because i noticed that ya keep saying to ohm it, but i dont think that it will tell anything exept short to ground. but even with a new stator i only got around 25v or 30v. hope this helps.
 
Re: stator problems

My factory manual states disconnect the stator from the R/R. Run the engine at 5K rpm. Stator output should be at least 80 volts AC between each of the three legs.

Resistance will not indicate if a coil is bad, because it can burn up and still have continuity. Residual carbon traces left over from smoked wiring will read resistance but not conduct electricity. Do the A/C test.
 
This would appear to be the boat I'm in now. Ohm'd out fine but no recharge. I'll be doing the voltage test this weekend and most likely going to Electrex.com and plunking down $155 on a new one.

you can do a conuty test to ground, if its open or shorted you will get a beep.

on the ohm test you can have a crack in the coating and still show good ohms. but it will show shorted to ground.
