lights on with ignition

Postby daicochlin » Fri Jul 18, 2014 12:53 am



Hi All, I'm from the UK but have a 1998 1500SE US spec goldwing. I would like to be able to run the bike without the lights on. Is there any solution out there for this. I'm pretty swithced on so should have the skills to tackle this myself with some instruction.

I'll double check but in the mean time,pull the cover off the relay box and look for a 5 amp fuse just below the relays.If you pull it,I think the headlights go off.
If so,you could extend the fuse contacts and wire in a "kill"switch to open that circuit and still have the fuse for safety.

I shall give that a go when I get back to the UK. Thanks

This would only kill the headlight.Are you wanting to go completly dark?

Yes I would like to be able to start and run the bike without any lights. it is not against the law in the UK to have no daytime running lights. I would always drive with them on but sometimes if I'm working on it and I need ignition on the battery drains real fast.

I'll dig into the schematic to see if I can find a break point.

I believe you will find it is the Blue/White wire coming from the starter switch. After a LOT of various trouble shooting, a break in this one wire was determined to be the cause of my headlights not working on my 96. I ended up adding a new wire (bypassing the factory wiring harness) to solve my issue. In your case, I suspect adding a simple single pole switch into the wire as it leaves the right hand control group will provide the outcome you seek. Virgilmobile will be along shortly with some good circuit wiring diagrams (he was very helpful in helping me get my issue resolved) and he should be able to confirm my assumption concerning this Blue/White wire.

That will kill the headlights buthe wants to go completly dark on a throw of a switch.
I'm getting to it soon.i think there's 2 seperate circuits involved.
I'll know more later when I can get off the phone and back to the computer.

I guess I misunderstood what the OPs was trying to accomplish. Thought he was looking for the ability to kill the headlights only. Well if anybody can figure it out, I'm sure Virgilmobile can. Will keep watching to see how this turns out.

It seems that the "Tail/Main/Meter/Position" relay is the primary feed for the lighting....However it also spreads all over the bike...
Pulling #8(15 amp) fuse will kill all the marker/running lamps,but it also will kill the turn signals,fuel gauge,temp gauge,all dash indicators,etc,etc...
Suitable for working on the bike but not driving...

There's 2 circuit wires involved...brown and brown/white....The gauges are fed with a black/green tied to the brown/white wire at point( S123 )This black/brown also feeds the indicator lamps..(side stand,rev,oil,OD...

If you cut a brown wire at a plug under the seat,you would loose some rear lights...cut the brown/white and loose some more but the front markers are still on...yet another wire to interrupt.

So as far as going completely dark and driving..No..there isn't any single circuit to break that will do this and still keep the gauges and turn signals..
There would have to be multiple cuts to just get the lighting to go off....

I do like the idea of being able to reduce the load should one have alternator problems on the road...

Should this happen...(OH NO..MY BIKE HAS A SUDDEN VOLTAGE DROP>I"M 50 MILES FROM HELP>>WHAT DO I DO>??) You do have a volt meter on the bike don't you???

One could pull 2 fuses (#8 and #5) killing all unnecessary drain from the battery and keep the bike running as long as possible....Just to get to a safe place...

I do have a voltmeter on the bike, normally reads about 13.5v when running.

That's about right.if it suddenly drops to 12.5 while your riding,you know it quit charging.
Personally I think everyone who rides any distances should have some type of charging monitoring on their bike.

Just got back from the middle east, The battery on the bike completely drained, even though I keep an optimiser plugged in. Bought a new Yuasa Battery, went for my first run in ages and my voltmeter was showing in excess of 16v. After a while the bike started spluttering and stopped. The battery was quite warm. I put the ignition back on about an hour later and started the bike it ran with only 10v showing on the meter and slowly ran down to 5v until it stopped again. (1) did the new battery do anything to my system? (2) Can the alternator overcharge and then stop completely. It will start again now with a boost, but will not charge. HHHHEEEELLLLPPPP

Your alternator failed.Possibly caused by a very prolonged attachment to a charger.It may have damaged the regulator circuit.
This possibly was caused by a relation to the original dead battery.
Why was it dead.?
Either the original battery failed or the charger failed.there both tied to the alternator
