Turn Signals on GL1500 do not work.

Postby Kemoloney » Tue Jul 30, 2013 10:58 pm



Hi everyone. I am in the process and near completion of converting my Interstate to an Aspencade SE. I know that sounds a little goofy but I wanted all the goodies such as reverse, cruise and air suspension and also wanted the lighted controls of the SE. At the moment I am having an issue with the turn signals. Neither left or right come on; not on the dash nor on the front or rear signal lights, but like many others have mentioned, the hazards still function properly. The left combo switch is brand new so I have ruled that out. All other lights including headlight, taillights, dash lights, side marker lights and reverse light function as they should. The other strange issue is that my after market cornering lights stay on all the time when turning on the key. Maybe they are driving lights and are supposed to do that.

I have scoured the Internet for answers and although there are some who have had similar issues, none really seem to apply to my problem when it comes right down to it. It has been a long project and now I'm down to figuring out all the little glitches before putting all the Tupperware back on. Oh, did I happen to mention that I repainted every single piece on my goldwing minus the saddle bags? Yep! I stayed with the original Candy red spectra color and had it mixed in aeresol cans at a local automotive paint store. Tri coat colors are fun to work with and the results were very pleasing for being my first time working with automotive grade paint. The paint matched my saddle bags nicely. I didn't paint those because they were in near perfect condition with no fading of the paint like many of my other parts. Wow, talk about becoming really intimate with sandpaper as well as with my wing.

So anyway, I hope someone out there can lead me in the right direction. Amazing how something that appears so simple can prove to be so complicated. Btw, all fuses and relays are fine. I will post this same topic on the other site with hopes that all minds can come together and help ease my pain. Thanks in advance for the help.

I can't help you with the signals. I would start with checking to see if I have power at the switch and go from there.

On the later years of Goldwing the "cornering lights" became driving lights and were steady on with the ignition switch.

What would be the best way to check for power at the switch? Is there a written procedure for this, maybe with photos? I want to make sure I'm testing the correct component properly.

Have you got a wiring diagram?

Yes. I have the big three ring binder which includes the service and electronic troubleshooting manuals. Parts of it I can understand while other parts are like studying nuclear physics for me. I can understand and test components if there is a troubleshooting section for my problem but unfortunately there isn't one for turn signals. And reading the schematics is like learning Braille for me. I may just cough up the big bucks and take it to a Honda shop to fix. Up until now, I have been able to figure everything out but this one has me stumped :cry:

I'll dig into the schematic...Keep in mind that the auto canceler operates the lamps...I think it's powered separately from the flasher...I'll get back soon.

Oh,by the way...does your horn work???

Another question...Did the original bike have auto canceling turn signals and in your conversion,did you also change the wiring harness.
There maybe wiring changes.I don't have the schematic for your bike,just the next year and I would need to know what model and year your fitting to it.

Hi Virgil. Yes the horn works. Everything works except the horn. After I get this figured out, I'll move on to the reverse and cruise options which are hooked up and may work but are untested.

Honestly, I don't know the answer because I have never ridden the bike. I bought it as a project and because a couple of gears were out in it, I swapped the motor with a low mile Aspencade motor and since it had the reverse gears, I decided to convert it over. Yes I have swapped all the harnesses as well as the cluster and the carburetor and and...lol. There are A LOT of parts needed in this conversion that the interstate does not have. All the way down to the bracket that holds the cruise rear brake cancel switch underneath the bike. It's definitely not for the faint at heart. As for the harness year, I believe it was from a 96 or 97 Aspencade. I don't believe there were much in the way of changes in harnesses over the years after 1990. Thank you Virgil for jumping in to help me out. You have no idea how much I appreciate it. Even we can't figure it out.

Oops. Sorry. Yes the horn works. Meant to say everything works on the wing except for the turn signals.

The turn signal relay and the hazard relay are under the trunk, near the front, and can be interchanged. Try swapping them and see if the problem moves with the relay.
On my 1500 the cancelling switch below the steering head was bad. I didn't find it, my mechanic did.

I already tried swapping the relays. Hazards work with both relays. I wonder if the canceling switch you're referring to can be tested before I buy a replacement only to find that it wasn't the problem.

My mechanic, who is very good, could not find a specific test for the switch. I gave him the go ahead to order a new one and it corrected the problem. With all the modifying and wire harness changing you have done you may just have a loose connection somewhere.

I think what I will do tomorrow is disconnect and reconnect everything and while doing that, spraying each connector with electric contact cleaner then add dialectic grease to each connection. Maybe I will get lucky and my signals will breathe new life. As for testing, there must be a test for the cancel switch. Nearly every electrical component whether a fuse, relay, switch etc. should be able to be tested for voltage and/or continuity. I just need to know the procedure. Maybe someone can help me with that.

Okay so I am lying in bed thinking...maybe my 92 interstate didn't have the self canceling turn signal feature, yet my upgraded SE left handlebar switch and Aspencade front harness are setup for turn signal canceling. Could this maybe pose the problem I am having; rendering the turn signals inoperable? Do I need to maybe add a turn signal canceling switch to my triple tree housing that has never had such a switch before, to possibly complete the circuit and make them work? Will my interstate allow such a switch to be installed even though it was never designed to house it? And finally, is it possible to bypass the turn signal cancelling and complete the circuit that way. i could care less about this feature. Can anyone chime in and let me know if this theory of mine makes sense and give me some advice? Are we aware of anyone else who has converted their Interstate to an A/SE?

Okay, after reviewing the schematic, it appears that my empty brown 6-pin connector behind the left front side of the fairing (C90) is supposed to terminate at the turn cancel unit, which I apparently dont have. With that being said, shouldn't I be able to jumper some pins inside this connector to terminate it in lieu of connecting it to a cancel unit? And if so...the million dollar question is which pins should I jumper to, in order to successfully bypass the missing cancel unit...thus giving me turn signals?

In the "C90" plug,there is a blu/black wire....Ground it....It should get the flashers started....They should not stop till you remove the ground....
The schematic shows that the canceler "box" controls the circuit ground to stop the turn signals.
I think,by just looking at the design,It's a latching circuit...When activated or triggered by the pink wire on C90,it holds the blu/black to ground till it's either timed out,angle sensor turned off or triggered off by the cancel button ( lt green/white).
If I'm right,I should be able to come up with a simple relay circuit that can replace the canceler unit.
You would have to manually push the button to turn off the turn signals tho.

I have no problem pushing in the button to cancel the signals. That must be how the Interstate was anyway. That would be great if you could come up with a procedure for a relay circuit. That would help get people by, myself included, until they got their cancel switch replaced. I will test the blu/Blk to ground and report back with my findings.

I think I've got a diagram that would work...It uses 2 relays..One is latching to ground and the other unlatches it....I would need you to do a volt/resistance measurment of the switches to verify the circuit.

While your "testing" things.Can you verify a couple of things with a test light.?Not a volt meter...
Use it in this way....Hook the ground clip to the white/black wire....I know its 12 volts....
Turn on the key...probe the pink wire....it should not light till the turn signal switch is pushed in either direction....When released back to center...does it go off.????

Same white/black connection....probe the light green/white wire...it should only light when the turn signal switch is pushed in...the cancel feature....

If these operate this way,and grounding the blue/black wire does operate the flasher then the above relay circuit should replace the auto canceler box....just no more "auto"

:idea: Well hot damn you figured it out! The blu/blk to ground made both signals work. I can't cancel either signal at this point but I assume that's what the procedure in your diagram is designed to do. As of now, either one of them stays on all the time until I turn off the key.

Congratulations! You've just created a test to determine if a turn signal cancel unit is bad. Take a bow my friend. You have helped many in the future. They just don't know it yet. but will when they search and find this thread :D

I am off to work now but will test when I get home. I don't have a test light, only a high end digital multi-tester. Do I absolutely need a test light or is there a setting on my multimeter I can use?

You know, the more I think about it, the more I'm leaning towards just installing the cancel unit. I found several on ebay with everything needed for under $40. Would this not be a better way to go?
