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.

  • 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.

I may be from B.C., but no it's not me thats fried...

So it seems my charging system om my 78 550 is kaput. Slow crank led to no crank led to kick start, led to almost no start. I took a look at all the electrical things and a wire had come off the black thing with the heat sinks (r/r?). I got a nice new multimeter for christmas and will be doing a stator paper job on it shortly, just wondering if anyone wants to hazard a guess on what, if anything (haha) I've cooked...

If there is not enough there to work with ,your looking at a new r/r.Around 60 bucks from www.z1enterprize.com
 
Older ones (like 77, 78 ?) had separate rectifyer from the regulator. After that the regulator and rectifyer are in one unit. But I dont specifically know about your 78 550.

What wire is loose? And did it get broke off? Or is it burnt-melted-fried off?
Then maybe we can guess weither someting has failed or if maybe reconnecting the wire might get it charging again.

Well before you dive into the R/R and stator, check your battery. Recharge it, make sure it's fully 'up to snuff' before you jump to any conclusions or make any heavy bets.

I'm new to this motorcycle stuff, but it seems I do have a separate regulator and rectifier. The wire looks like it just broke off the middle of the rectifier. I jammed it back into the connector and squished it with some vice grips, and it still isn't charging, so there's a pretty good chance the connection sucks. I'm going to redo the connections and hopefully that will do it.
