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...

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.

r/r keeps killing battery?

Thats definitely a full short to ground. I actually meant that the yellow wires can be pinched inside the cover. If you are lucky that may save a transplant.
Anyway you have a spare, so good luck!
 
Electrostat opinions?

Electrostat opinions?

Pulled the stator cover off and yep it's fried. A couple coils on it were a nice crispy black and the wires from it are brittle as twigs. Still haven't pulled the one off the parts bike yet. Still thinking about just ordering a new one instead. I'd really hate to be stranded because I put a used one in. I'm steering towards the Electrostat, both the r/r and stator. The cost is worth piece of mind. Any electrostat users opinions about the durability and output?

Pulled stator off parts bike this morning and it looked like new. The wiring also appeared in good shape as well. Tested again with meter, still good. So in it went. Also swapped RR and did a lil fancy wiring. I didn't mess up the gasket so I didn't even need that. Slapped together, start bike... 13.9V at idle and no leaks. Did stator paper checks again. Lucky me! Total cost: $0.00 + headache. Now to spend money saved on that new back tire. Thanks again for the help.

Wow thanks BassCliff! Mine is the one on the left. I'm pretty sure it is either aftermarket or off another brand of bike. I just hope it is not fried from being on all the time. I guess I'll find out tomorrow.

Check the Stator and if it is OK, then try the following...

The Silicon Controlled Rectifier (SCR) is controlled by the Zener Diode below it.

The Zener turns the SCR on and off.

When the SCR is turned on, it sends the output of one of the legs of the generator to ground, thus curbing charging.

When the SCR is turned off, it does not allow the output of one of the legs of the generator to ground, thus the charge is consumed by the battery.

[Edit] I guess I am too late... This trouble shoot tip still holds though.

If you fully charge your battery (for instance) and then hook it to the bike and start the bike, the Regulator/Rectifier should replace the amps that were drawn from the battery by the starter.

So, it charges for a bit and then reduces the charge so that it does not overcharge the battery.

So, this might be what is happening, the SCR is always turned on...interestingly enough this is how a lot of SCR's fail, you cannot turn them off.

A positive voltage on the Zener should turn the SCR off, and thus the voltage at the battery will decrease since only two legs of the generator are charging. To do this simply put jump a wire quickly to the Zener.

You can trace where this wire goes to the wiring harness and unplug it.

To turn on the SCR, simply ground this wire.

The Zener is there simply as a switch. By varying the voltage to the Zener you will be able to control the charge to the battery.

If you do not see any changes in charge voltage, your regulator is whacked out... to put it technically!
