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...

    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.

Gear Indicator Lights

I took off the covers on my left side for polishing awhile back and since then my gear indicator lights have not been working. All connections are correct in the bucket so the problem must be in the case. Has anyone maintenance'd this before? I'm not sure where to start. All other lights are working correctly and my charging system is great.

Thanks,
GSP
 
There's another connector between the bucket and the case that may have come unplugged. On mine it's a square plug and a bullet connector.

How about the netural light, does that work?

THe netural swtich is in the same switch as the gear selection swtich (like netural is a gear shift position).

If netural light does work but the gear numbers don't, I would suspect the connector up on top, because the gear positions are in a multi connector, but netural goes thru a separate single conector.

If netural doesn't work either, then I wouold suspect the Org/grn wire in instrument panel (that powers all of them) ... or the ground wire to the switch.

Yeah. I have no neutral either. I double checked the sensor under the left cover and reinstalled it to make sure it was set properly. Still nothing. I haven't taken the tank off yet to follow the wires but I just - very thoroughly, I might add - inspected the wiring on the bike and I'm pretty sure the issue is not a loose ground. I didn't realize the sensor was so sensitive and admit that I had it out and exposed to rain for quite a few weeks while I was polishing the cover up. My hypothesis is that the actual sensor is bad. How likely is this?

Will take the tank off and touch base on all connections when the weather permits again. In the meantime I will start shopping for the sensor.

Do the horn, brake light and turn signals work?

No, this is not just a general electrical check, all of them, and the gear indicator lights, are powered by the same fuse.

.
 
When you removed the switch, did you perhaps misplace the little spring and/or steel nubbin living inside the shift drum that contacts the switch?
 
Did any of the wires get pinched when putting the cover back on? You could have pinched and killed the wires replacing the case cover.
 
The lights work by grounding a little button against the engine and on each little contact in the engine connection. As you shift gears the button moves in a clockwise direction moved by a shaft in the gearbox. 12 volts arrives in the dashboard on an orange wire and powers all the light bulbs at once. As each bulb gets a ground connection from the transmission they light.

I replaced my bulbs with LEDs because they are 4 dollars a piece. I used a 2,2K resistor in the number 6 position to lower the 12 volts a bit and limit current. This is a popular mod.
 
Ew, Steve has a good idea. Anything else work that is on that fuse: instrument lights, horn and such?


Or..
Next time you are at the switch: test things by grounding out some of the wires/contacts down there.

.
 
For anyone that might read this with interest in the future: There is a spring and contact that ground onto the gear sensor. I was missing both of these. Upon further inspection the sensor was not the problem. Hope this helps someone else.
 
While we're on the subject, I've got four gear indicators for my 1982 1100e. All of them show the correct info during the day.

Anyone got one that actually lights up?
 
There is a diff bulb for each gear indication? I ask b/c only 3rd isn't lighting up for my GS550...
