GL1500 idiot/screen light issue

Postby bjatwood » Tue Oct 21, 2014 9:44 am



Good morning folks,
Rode the bike to work today, 1998 GL1500 SE. When I went to start the bike the only "idiot lights" that came on were the neutral and side stand lights. The display screen and the cruise on/off, R light, did not come on. I rode the bike to the gas station and the "lights and screen" powered up and worked. When I restarted it after fueling up same issue. 2 or 3 miles down the road the lights checked themselves while riding it @ 55 mph and the screen came on, and idiot lights went off and the LCD screen display worked.
What do I look for to trouble shoot this recent issue? Only issue I've had with this bike EVER...

Intermittent functioning lights can be hard to track down,so be patient....
You most likely have a poor ground that operates the display....This can be at the harness plug,ground lug or the display connections...
The power for all of this is from a relay #3 but it does feed the side stand lamp which works...thus the reason to suspect a bad ground....
Where to look....Here's a link to some more info..http://www.goldwingfacts.com/forums/2-g ... emlin.html

You may find this...


If you locate the problem,post pictures of it.

Relay #3 ...try checking Relay #3 Remove...clean re-install or try with a similar relay...Tearing down to get to those ground plugs require removing a lot of the tupperware from the bike...there is one on each side of the bike.

If it was a bad ground issue..you would have seen other things possibly..like your turn signal indicators glowing..not properly working...loss of brake lights...I really suspect its relay #3

bjatwood -

I've just had the exact same thing happen on my '97 (like, a 1/2 hour ago!). Turns out that on '97 & '98 wings the circuit boards behind the LCD panels weren't properly cleaned & sealed at the factory, and moisture (in the air - actual wetness is not required for this to happen) can cause them to shut down. When the temperature gets high enough to dry them out (after, say, riding for 10-15 minutes), the LCD panel will reset, making several of the idiot lights cycle (while the engine is running), and the normal display will return. The clock may need to be reset. Apparently, another symptom is the clock starting to lose or gain time, even while the display is working. I've noticed this over the last couple of months, although daily riding seems to stop this from happening.

There are threads out there showing how to remove/clean/seal/reassemble the LCD panel's connectors, circuit board, etc.

Conversely, several out there have chosen to simply ignore the problem, finding that when it happens, everything consistently returns to normal once the bike is warmed up. I haven't decided yet, on mine...

In my case, I let the bike run up to temp in the garage, shut it down, left it for 20 minutes or so, and when I tried it again everything was back to 100% functioning again.

Just thought I'd let you know, in case the relay test doesn't fix it for you...

Thanks for the input. Mine does this in the mornings, but after work when the bike has been sitting in the sun all day it does not "mess" up when starting it. So I believe that the LCD screen is probably not sealed correctly any longer and taking it apart cleaning or sending it to Sierra Electronics this winter will be on the to do list for sure.

I just recently did the remove, clean, reseal of the PC board for the LCD panel...and although it's better...its not prefect. On really humid days, the display will still blank out until it get warmed by the engine or sun. I'm just going to live with it as I had previously...it's not THAT big of a deal...unless I need to add air to the rear shocks.

Okay, that's weird. Does the screen come on again at the ACC position?

On another note, mine's gone out again already. It's raining so hard here the last couple of days that the roads are flooded, and my garage roof is leaking in several places. Cardboard in the garage is turning to mush because the air's so damp. Unfortunately, I can't afford to heat the (uninsulated) garage. Don't like the idea of long-term dampness problems with the Wing's LCD (in case it becomes permanent), but I don't have any options.

What I think about this news is that you have a faulty ignition switch that has a worn ACC contact inside of it, and the LCD is not the cause of the problem, it's just a symptom.

Does your radio shut off when your LCD shuts off?

Not sure about the radio Scott. I do not use the stock radio as I use Slacker Radio via my Android phone sent BT to my Sena SMH10 unit.
I will try the radio to see if it goes out when the LCD does. I do know that my C-Control will come on but not set when the LCD is out tho.
With the screen working in ACC mode wouldn't the "RUN" contacts be worn instead of the ACC contacts Scott in the ignition switch?
