1998 GL1500A Position Lights/LCD Display

Postby djlundwall » Wed Apr 25, 2012 6:46 pm



When I purchased my ride I didn't notice that the "position" lights were not working. I replaced them with 194 LED's, and they are still not working. I am wondering if this is part of the problem I am having with the LCD display... When I turn on the bike the display will ALWAYS have the time of "3:20" or soemthing like that. When I change the clock setting it works as long as I am running, but when I turn the bike off I loose power to the clock, resetting it the next time I start the bike.

I am wondering if these two issues are really symptoms of the same underlying issue.

Any ideas?

Many thanks!

I'll look at the schematic as soon as I can download it.In the meantime,look at all the fuses.There has to be a "hot all the time"wire to the radio to keep the time set.It should be fused.This dead circuit MAY also involve the cornering lamp circuit.Don't know yet.

This is the quick find.I can keep digging if the fuse is not all your problems

I will check the fuse on 13. Many thanks.

I will post my findings.

Alas... :cry: Although the fuse was blown... which accounts for the clock issue, the front position lights still do not come on. :cry: :cry:

This is a bit more involved, however on my 88,neither would work.I found that both the relays that are strapped to the harness above the lights were bad.pull the plastic off and test probe there first.as soon as you turn on the key,both relays should energize.there used to keep the lights OFF until the cornering circuit kills the relay and then the contacts apply power to the lamp.I'll compile the schematic ASAP.

Here's the schematic.I found the relays up just under the faring.In front of the radiator opening,There small,maybe 1/2" x 1' x 1 3/4' long.They have 4 terminals on them.I used a relay from a ford car.Does the same job.Mine would click,but no volts came from the contacts.If you notice,with the key on,2 terminals will have 12 volts.One is from the switch and the other is main power.When the turn signal is activated,one will go dead and the wire going to the lamp should get power.

I'm wondering if we are talking about the same thing ;)

I'm not having issues with the "cornering lights" per se, but the "position lights" which I have always assumed to be the lights between the headlight and the signal light. I think the light is a "194" base.

SO... my dilemna is that these two lights (again, right between the L and R turn signals and the two headlights) do not turn on. I have replaced the original bulbs with LED's, to no avail.

Any ideas :?:

Yup,your right of course,but you now have a overload of information about cornering lights too. :lol: Darn potato..or is it potatoe???
Well here's more to look at...So there.
Are the LED's reversible in the socket? LED's are polarity conciseness.They do have a plus and a minus terminal.

Thx for the reply. I will check the polarity, but I seem to remember that there are many LED's that are not polarity sensitive. I believe I purchased these types of LED's (non-polarity). But I've been known to have been wrong before (just ask my wife :D ).

A lot of the larger LEDs that have wedge-type bases have rectifiers inside so that they are not polarity sensitive. However, I've found that the majority of the smaller wedge-type LEDs (such as 194) are in fact polarity sensitive, and will not light up if installed backward. Worse, they have a shunt diode in them that provides almost a dead short if the LED is installed backward, to protect the LED itself from the reverse bias that would otherwise destroy it. Those shunt diodes will heat up and burn out after a while, which then allows the reverse bias through to the LED and kills the LED.

Ask me how I know. :)

Who am I to second guess an Electrical Engineer (or the like) ;)

I will take out the bulbs and turn them around... I will come back with my results.

Thanks all!!!!

Let's just say that I might have let some of the magic smoke out of my LEDs. :)

Besides the fact that electricity is just compressed smoke......I have learned that lights do not "give off light"....
In fact they are a darkness collector....
Look at any lamp that has failed or gotten "dim"..you will see the darkness has collected inside the lamp.
I personally saw this in florescent lamps.When enough darkness has collected in the ends of the tube,they will cease to collect any more.

Haven't you seen a marker lamp that you would call "dim"? when you examine it.a bunch of darkness has collected in side and is restricting it's ability to collect much more.

Just the observations of someone that really needs to go for a bike ride....and soon. :)

I agree with you - better go for that ride - right now!

Ahhhhhh,the sweet smell of the chemical plants.Just what I needed to cloud up my thoughts. :) Chlorine,dimethyl,toluene,all mixed together with Exxon mobile and BASF into a mind numbing concoction of aromatic something or other......Yup ..It's working :lol:
