my project - re-do the electrical wiring

Postby GillesGLW » Tue Apr 21, 2015 2:00 am



Hi everyone!

Greetings from Switzerland where the snow has melt and the time to ride again has come!
Shortly about me (as it's my first post here), I bought a Gl1500 from 1990 end of last year and I'm currently working on turning it into a "stock bike".
My idea is to bring the GL back to it's intial state where it was a bike made by Honda (meaning with Japanese/American way of working), without cheap accessories mounted.

The challenge when I bought the bike was to remove the windscreen wiper, all the "cheap" switches and connectors.

So it started with that:





After a few hours and a bit of cleaning, I managed to remove this:


Yesterday I received te follwing items from Cyclemax (thanks again to them, they are so professional!):
http://cyclemax.com/inc/sdetail/gl1500_ ... ignals/749
http://cyclemax.com/inc/sdetail/gl1500_ ... ight/85913
http://cyclemax.com/inc/sdetail/gl1500_ ... lights/455
http://cyclemax.com/inc/sdetail/gl1500_ ... /129/23042
http://cyclemax.com/inc/sdetail/gl1500_ ... /129/14364

Now my challenge is to re-wire everything correctly and forget about it for the next 10 years :D

Has anyone done that already? I have the Honda wiring diagram to help, but any advice will be welcomed!

Thanks,
Gilles

Sounds like you have a pretty good "Handle" on your new project. My advice is to solder and heat shrink all connections that you have to make to the origonal wiring. When you get her done, some pictures of the bike and your country would be very nice to see. Good luck on a quick fix so you can enjoy that good riding weather. :)

That GL1500 power plate is a good product - I have one in my GL1500. When you get it, pull the relay out of it and dispose of it in the nearest receptacle, then replace it with a quality automotive relay, at least 30 amps. I had a problem where the voltage on the accessories I was running through that would drop whenever current draw went up, and it turned out to be the cheap relay they used (it would heat up - it said it was rated for 30 amps, but it definitely wasn't).

Also, I ran all my wiring through wiring looms on the bike. It keeps things neat, and prevents abrasion of the wires.

Thanks to both of your for your reply!

Indeed, I have quite a good handle on this project, I know what I'm trying to achieve. But the real challenge will come from the wiring and how to do it.
As turn signal and brake bulbs are all 12V, my idea was to plug the additional turn/brake signal on the existing wiring (with proper soldering!), does that make sense to you?

The power plate looks like a great product, but now that I will install it, I wonder what is the added value of this plate vs. the use of the accessories' box on the left side of the bike, below the seat.
I know, I sometimes buy stuff and then later wonder what it is used for :D

The accessory terminal on the fuse block is limited to 5 amps maximum. The power plate lets you supply considerably more (up to 30 amps), and lets you segment circuits from one another, so that they can be fused individually.

Many thanks!

Now everything Is clear :)
Hopefully for me, I Will only connect cornering lights and trunk lights. I dont have Much accessories for the time being.
I Will start working on the bike on Friday, I will keep you posted!

I will start working on the bike tomorrow, finally!

My idea is to prepare all the cabling first and then connect it later on a rainy day.
I plan to use the Clymer electrical diagram to re-wire cornering lights and back lights. Does anyone have other electrical diagram I could use?
How do you connect a relay? I'm new to this....

Thanks!
Gilles

I'm not sure, but there may still be the plugs for the cornering lights allready on the bike. They would be up on the frame above where the lights are located when installed. You may find the same thing with the trunk lights. I hope so as it will make your project easier. :) It may be that when they make them that they all use the same wiring harness, but not sure. ;)

Good point, I will check that!

From what I've seen, apparently there was no cornering lights nor trunck lights initially. Everything seems to have been done in a cheap way, except for the side lights on the trunck, which seems to be coming from Honda! ;)

If you look under "manuals" at the top of the screen, left hand side, then there are a number of manuals that you can access, and there is one for electrical troubleshooting which could assist you in your work.

I'm hopeing that as many of these lights, etc , are sold as accessories that the wiring may all ready be there. Then it is just plug it in and go. :D Which model do you have?

I have a 1989 Gl 1500 and unfortunately I realised today that nothing was plug and play!

So I spent a bit of time soldering this afternoon to make sure I could wire everything correctly later. So the saddlebag lights should be fine now. I just need to see how to plug, turn lights, break lights and rear light.

Sad thing, the spoiler light does not fit my actual spoiler.... no change to make it fit...

A quick question to those who have "twin" turning lights on the back of their Goldwing, how did you wire them?

I got this from Cyclemax:
http://cyclemax.com/inc/sdetail/gl1500_ ... als/83/749

But of course, no plug for the rear/brake light, so I'm considering wiring them all manually...

Any idea?

I will share this with you, it is a generalized wiring plan for all Hondas. It may not be exact on every wire, but I think it might help answer a wiring question or two as you progress. Keep in mind this a general plan Honda goes by and no means exact to any model Honda makes. Good Luck and keep us all posted.

Thanks Chuck!

I've been able to identify the turn light and the brake one. Now it's a question of wiring them all properly!

By checking the link above, it says that the wiring instructions are included with the lights. The wire should be in there too. I just realized that we never answered your question about a relay. A relay is an electrical switch that when powered completes another circuit that usually carries more current than a normal switch does. (like a solenoid) Most have 4 plugs. Two should show continuity all the time. These are the wires to a coil that becomes a magnet when powered that closes the contacts and completes the circuit on the other two plugs, This allows a switch with a low current to switch on a higher power circuit and not burn up the switch. Hope that helps in a simple explanation. :) There are also relays that open a circuit when energized also, so there are relays for differient applications.
We still don't know what model GL 1500 you have. SE, Aspencade? They have lots of differiences in what is on the bike.

Thanks for your reply, I'm now clear on what a relay is. I didn't understand that is was acting like a magnet generating electricity. For me it was a kind of fuse.

I can see now why I need them for the cornering lights which are both 55W! Do you know if a relay would also be needed for the trunk lights?

About the Goldwing, I can definitively tell you it's a 1989, but not sure which version it is. Is there an easy way to know it?

For the lights, there was a paper with instructions.... saying that I should plug the lights in the existing cables.... that I don't have :-)

Wait a minute, you say that you have no plugs for the trunk lights? They plug in or else you couldn't change them out. Follow those wires back in a little further. All the lights have a plug in the wiring. Look into the existing light sockets and follow the wire. May be under (or above as it is under) the lower trunk cover, should be 4 screws holding it on. Be careful of its front connection (the cover). Green wires are ground.

I do have a plug for the central light which does both brake and light, but no plug for the left and right trunks.
The only plug I have is the one for the trunk side lights.

My assumption is that the bike (for the Swiss model) came with little lights due to Swiss legislation. Normally additional lights other than front and back lights are not allowed. Since the bike is 25 years old, I think all the lights that have been installed, came later.

The problem was that the wiring was not "Honda approved", and looking cheap. Ideally I would like to find a harness which has all the plugs in, but not sure it exists!

I think I'm on the right way now. I made a test and everything seems to be working fine with the rear lights!

Just one question came to my mind: will the rear light support the extra connection I made on it for additional running/brake lights? I know the rear light is a 12V with probably 5 or 10 W. Should I add a relay somewhere so that when I break all the lights are visible? Same when the running lights are on, is there any issue if my saddlebag lights (http://cyclemax.com/inc/sdetail/gl1500_ ... als/83/749) are plugged on the central rear light?
