    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.

No headlight/taillight/turn signals - 12.6V at the fusebox

'80 (or '81?) GS550 L, non-running.

The electrics used to work (minus the turn signal, L would flash, R would just stay on). Working on various pieces getting it ready for the road, and decided to take another look at the turn signals to see if I needed to replace the flasher unit.

Well, turned the key to "on" and the neutral and oil dash lights lit. This time though, no headlight, tailight, or turn signals. Can't check the starter since clutch cover is off. All fuses are good (ohmmeter), and have voltage when they're supposed to (voltmeter). Voltage ground was referenced to the frame, not the battery neg post.

I would think the lights would ground where they're mounted. Maybe I undid a main wire or something?

Stuff I have off right now:
Tank
Seat
airbox (not removed, but unfastened)
carbs

PS - the bike hasn't ran since I've owned it, so it's not an over voltage issue.

Any ideas out there?
 
I don't have a wiring diagram for a 1980 GS550L, but I have a color wiring diagram for a 1980 GS1100L. Hopefully, it should be almost the same wiring setup. If you want to try it, PM me with your email address and I will send you the diagram as an attachment.

MINE DID THE SAME THING ONE TIME, I REPLACED THE FUSE EVEN THOUGH IT SEEMED TO BE OK AND THE PROBLME STOPPED.THE HEADLIGHT WIRES ON MY GS 1000 ARE YELLOW BLACK AND WHITE.THEY ARE LARGER DIAMETER THAN OTHER WIRES,PERHAPS ONE OF THEM HAS COME LOOSE.
 
If your getting an audible signal on your ohmeter {if it has it} across the fuses then they're working.
Getting V on both sides of the fuse, then they're working.
Take your fuses out and GENTLY twist them to make sure they are not comming apart-

Take your V/M and check for V at the headlight PLUG-
You should have Voltage on one or the other side
{ones facing like this --> | } depending on if it is on the low or HI setting.
The Horizontal one at their ends is the Ground.
Check V in the Socket {using the Frame as the Ground}, move the switch and check both Vertical Parallel Slots both times while testing.

You may have lost power somewhere in the harness under the tank area {also could have a bad ground}, there are some quick plugs for the left hand controls {for the headlights} running in that area.

GL,
Ron
