1977 GL 1000 Tail Light.

Postby danielklinger » Fri Mar 04, 2016 9:52 pm



I'm a new Goldwing owner. I was working on the rear lights on my wing. Suddenly the tail light went out. When I turn the switch on the on position the rear tail light and front driving lights don't work. The brake light works. I move the ignition switch to the park position and I get the tail light to work but still no front driving lights. Does anyone have some suggestions? How do I test the ignition switch? Thanks for your help. Dan

The fact that the light works when in the Park position says that the bulb and the wiring is OK. The only difference: when in park, it uses a different fuse. Check your taillight fuse, I think you've burned it out.

Thanks for your feedback. I really appreciate you taking the time to write. I did discover that the diodes didn't have continuity. I also discovered that the headlight and taillight resistor was bad. So I'm replacing both of them.

Thanks again for your help. Dan

I continue to work on my tail light problem. I have replaced the relay diodes and the front and rear light resistor. But when I turn my ignition switch on the run position I still have no rear lights or runnings lights in the front. You suggest I check on the rear tail light fuse. Where is it located? I wasn't aware that I had a tail light fuse. I guess I'll have to look around for it. Thanks for any feedback. I certainly do appreciate it. Thanks, Dan

The 75-77 GL 1000 has a reserve lighting module that is a common cause of these is type issues.
Do a google search on the reserve lighting module there are how to tutorials for jumping around this obsolete unavailable module.

Also the fuse block prongs that holds the accessory fuses can become oxidized within and cause an poor fuse contact and odd or inconsistent lighting issues. I cleaned mine really well with a small round wire brush.

Thank you for your replay. I'll have to check that out. I don't remember seeing the Reserve Lightning Unit. I'll have to check the left side of my motorcycle. Thanks again for your help. Dan

Thank you for your feedback. I did check on that and I don't think I have one. Eventually someone who had the bike before me bypassed the Reserve Lighting Unit. I did wonder what is this? Does anyone recognize it? I was just wondering.

I did a little more investigating and I discovered that where this black box is is where the Reserve Lighting Unit use to be. Mmmmm now what do I do? still thinking. Thanks for your feedback if you have any. Dan

Yep,
someone maybe previous owner has done away with it and done some, um, creative rewiring,
So, I would start at the fuse block then check the bullet connectors that feed the running lights,
It shouldn't have anything to do with your start button switch if your headlight is working.


Since the wiring has been, shall we say modified, I would scrutinize all lighting connections and grounds for them as well.
Check them ahed of the false tank in that wad of wires and under the seat and so on. It might turn into an exploratory project.

Here is a picture of an unmolested 77's electrical component layout including the oem reserve lighting unit.

Thank you Maintainer for your feedback. I figured out what that black box is...it is the relay for the horn. So I'll need to check the wiring and the grounds. Do you think the ignition switch could be bad? Just wondering. I did trace the wires from the tail light all the way to the front wiring harness going into the ignition switch. I had power all the way with the ignition switch in the park mode. Thanks for your feedback.

Thanks, Dan ;)

Well that kind of hard to say acting as an keyboard quarterback. I did replace just the electrical part of my ignition for another reason it's about 30 bucks and easy to change out when in doubt. I did it this way to keep the original key fitting everything.
Personally I would consider the ignition a remote possibility for this.

Thank you Maintainer for your thoughts. I guess I'll just keeping looking and testing. There has to be a bad connection or a loose wire somewhere. Someone told me that it couldn't be the wiring since the tail light works in the park mode. What do you think? Probably there is a fuse blown that I haven't found yet. Thanks...I appreciate it, Dan

Thats true, I must have skimmed over the tail light working. I was going on no running lights.
So lets see now.
Normally on the 1000 the headlight, front signal lights, and tail light stay on as running lights.
The rear ambers are signal only single filament lights.

So with the key in park position illuminates tail light only.
I confirmed this on both my wings.

Hmm, I'll have to think about this.

Hello Maintainer, to clarify what is going on in the ignition "on" mode I have front and rear turn signals and brake light. I don't have front amber running lights and tail lights. When I switch the ignition to the "park" mode I have tail lights and I still have break light. In the "park" mode I don't think I'm suppose to have front amber running lights...although I'm not sure. I hope my clarification helps. Thanks, Dan

Oh I forgot...I do have a front headlight. Someone along the way who did the creative wiring put the front lights on a separate toggle switch.

Tail light only illuminated with the key in park position is correct, it doesn't light the front ambers in this mode.

I'm not sure now that I have your situation facts straight. Square one, keep looking study a good wiring diagram if you have one.
