    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.

Ricks Electrics in NH. I think I paid $100 for my r/r from them. Keep in mind that 9 times out of 10, the reason it fails is due to a fault in the wireing somewhere else on the bike. Better plan on a long date with a multi-meter and a wireing schematic before you put the new one on.

They were Electrex, the original sponser of the GS Resources many years ago. At one time they were the people to go to for regulator/rectifiers and stators but I've heard that their quality is now suspect but I can't personally attest to that.

One of the major wiring faults that can cause this is an inadequate ground wire from the r/r to the battery.

In the process of regulation, the r/r momentarily shunts the excess power straight to ground. If there is not a good ground, it has nowhere to go, causing problems.

I see they have applications listed for 79-82 GS750L but not the regular non-L model. Does the L matter or will this work for the plain old GS 750?

what about the pre 79 bikes? Will a 78 E model work with this?
 
Some of the earlier bikes had separate rectifiers and regulators.
Not sure what years or what models, but it is right in that '76-'79 timeframe.

It will work for the plain old GS750.:)

It will work. Your bike came with a separate rectifier and regulator. Later models use a combined R/R in one unit. To install on your bike, remove the old parts and rewire it to use the combined R/R.
 
the 79 L model GS750 is different than the other gs750's that year. The 79 L model shares the recifier/regulator as one unit as seen on following years tscc models. The 77-79 GS750 and GS750E have seperate rectifiers and regulators.
