Turn signals act like emergency flashers?

Post by BrockRock »



I have a 1996 GL1500 aspencade with a turn signal problem. when you use the turn signal switch which I cleaned and inspected. the turn signals act like the emergency flashers. checked and swapped all relays. the 2 under the trunk are the same. the one in the fuse box are the same as the others so did the swap there. replaced all bulbs. looked at all wires for shorts. looked at grounds but how many are there? back to the Problem the turn signals act like flashers in left or right position. the auto cancel does not seam to work. I have been wrenching on it for a month.

First Gold Wing Here and bought it in Denver road it back to SLC tach broke, turn problem, criuse only works at 75 mph. radio is a piece of crap. so new speakers. not much better. and it smokes on start up. sure rides nice thought. lots of problems. fixed every thing but the turn whats the deal?

Is this a new problem or did you get the bike this way?
Any aftermarket lighting? That would be the first place I would look. Another thing is people do all kinds of strange things to the stock cornering lights, so things might be cross wired there.
Then get out the meter and start testing.
The switch pod is a prime suspect. Unplug it and test the switches and the bike left and right wiring. The hazard switch has known issues when unused for long periods.
Do you have the factory service manual or other good wiring diagram?

The bike is stock , no lower turn lights. Some one took out the emergency flasher switch when i got it. Road it 20 miles on the way out of Denver and thats then the turn signals turned into flashers. When I got it they worked. Sounds like these bikes have nothing but electric problems.

No idea on the turn signals, but agree you need to check the wiring and look within the handlebar switch to see if something there was messed with or somehow got crossed, and if the auto cancel does not work, look into that module (don't remember the name or location of that though).

As for your cruise control, does it only set at 75 mph, or it will set at any speed above 30 mph up to 75 MPH?
If the second, that is how these things are designed (actually an 81 MPH max speed for the cruise, but speedo error could make it look like 75).
You can bypass it by doing this how to.

I was going to ask what happened when the emergency flasher switch was pushed but then I saw there was no switch. I would recommend getting all of the parts together for the left switch assy and then see what you have. There is no telling how the insides of the switch was left so start there.

Perspective. You have a complex motorcycle that is now an antique, multiple previous owners, possibly left outside at times, chopped and hacked wiring that you've already found. No reason to be surprised or disappointed that some electrical issues will crop up. There are mechanical features that need attention as well (timing belts, drive line maintenance, hydraulic fluids).

What Andy said. Welcome to the forum. If they are treated right and the maintenance is kept up to date, the gl1500s can be very dependable.

It sounds more like your bike has electrical problems. They were installed by a previous owner who didn't know much about electrical work. You already have some good advice about what to check for next. I would start with the missing emergency flasher switch and associated wiring.

Did that got another switch assy off of ebay put that on and the emergency flasher switch worked great. Still same problem with the turn signals. Thanks for your input 👍 at this point ill take any ideas out there maybe I missed something . Looks like shes going to the frame on a tear down . Oh im 61 years old and have been wrenching on cool stuff for years
If any of you guys are sledders, I made BRTECHRACING hoods for 27 years the wing is kicking me a bit so again thanks 😊 for the help

I've been looking at the wiring diagram and I wonder what would happen if you pulled the hazzard flasher out to see what would happen and then the turn signal flasher. The regular turn signal flasher is enabled by the turn signal cancel switch (which you say doesn't actually cancel) and then the resulting flashing pulse is routed to the proper side lights by the turn signal switch and the hazzards (not controlled by the cancel switch) bypass the t/s switch. Somehow we need to seperate the two systems.

well the emergency flasher system does not flash at all at its flasher. its like each side is bleading to the other flasher.

Ok, so no hazzard flasher relay action, that's interesting. Let's see what we know so far and tell me if I understand something wrong. The turn signals operate like they were the hazzards and the hazzards seem to work ok but are somehow using the turn signal relay. The fact that the signals work at all and can be canceled manually says that the signal cancel works at least to an extent. It would be useful to know if the cancel control unit cancels the lights after you drive straight for about 1/10th of a mile as it should. As far as no cancel after a turn, try turning the front wheel to one side or the other and look up under the front fairing above a black plastic cover at the bottom of the steering head, the turn cancel unit is screwed in from the botton with two screws and there is a small lever that goes toward the rear and is fastened with a third screw. That lever is what tells the cancel unit that the bike has turned so if it is not screwed down the cancel unit will never know that a turn has been made and of course the lights will continue blinking. Lastly, that left combination switch. There are actually two parts to the turn signal switch, one contact gives a signal to the turn cancel unit to ground the turn signal relay so it can work (the manual cancel button sends a signal telling it to shut off the turn signal relay and therefore the lights) and the second part directs the resulting pulsed power down a single wire to the switch which then sends it to the correct side turn signal lights. I am thinking that there is an issue with the switch contacts that would cause both sides of the turn signal switch to be powered up or possibly pinched wires that would connect them. Since the hazzard switch is right there next to the turn signal switch and that is not acting properly that switch and it's wiring is rather suspect in my mind.
So, if I have been able to make this any clearer than mud it will give you some things to check out.

Great replie! Going to tare into the turn cancel in the stearing head.. right now on planing to remove the whole upper fairing. Ill be gone for a couple weeks so the wing will be setting all torn apart at BRTECHRACING R&D room. Again thank you guys for all the help. Brock.

Remember that the turn cancel unit may be just fine, it does at least some of what it should and more looking would be needed to say it's bad. The turn sense lever is outside where you can see it and turn it if needed to test. The PO had some kind of reason for taking the hazzard switch out so who knows what you'll find.(or maybe him taking it apart is what caused the whole mess)

I am leaning more and more toward a wiring problem.

Btw, the turn signal relay has a white plastic plug, the hazzard relay has a black plug on it. It will help to make sure that we are working on the correct system.

Sorry, just saw this post now. Been on a 7 week holiday in my van out in the Maritimes. This same thing just happened to me for the second time, turn signals acting like the hazard flasher. I had to look at a previous post I made a few years ago on the same issue. I couldn't even remember where the hazard flasher switch was. Anyway, I blame it on my 2 and half year old grandchildren pushing all the buttons on the bike. The hazard flasher switch had been depressed, and it didn't return. Sprayed some contact cleaner in the switch and worked it back and forth for a while. As soon as it released and worked properly, the turn signals worked properly. Always look for the simplest solution. BTW, the hazard flasher switch is beside the turn signal switch. Now I know.
