1975 gl 1000 wire color codes

Postby Roblittleone » Sat Mar 06, 2010 11:36 am



I removed the wiring harnes and replaced it with another one which wasn't burn. Now traced all the wires for break with a contnuity test that all shows good but when put the battery put on it only has the turn signels working but nothing to the starter. The 10 amp.fuse has no power to it.
What I'm looking for is the color code and which wires are hot or a picture of the wire at the neck which runs the coil and everything else. I used the the chart which you have on your site but didn't help. I have been at this a to long time never had this trouble before.

Thanks

Slip over to NGWClub.com and visit Shop Talk, wiring pic's there.
you can go exactly .4 miles with the petcock turned off.

Hey Rob
Haven't seen the actual one you are seeking.
I changed the harness on GL 1000 bike, found i did not find good ground for the coils and the battery--i grounded the coil to the frame , found a good ground for the battery under a motor mount , then went through the system cleaning connections etc
My 30 amp wishbone fuse was a little wonky, so i swapped that out with a car 30 amp fuse , found at the local CTC store (automotive) and soldiered it into the circuit
Maybe this will help, maybe not !--Let us know how you are doing
Cheers Terry

Thanks checked that out tried it didn't work but thanks. I found the color code for the wires. Thinking of trying another wiring harns. I cleand all of the connections. the doesn't seem to be any power coming out from the diode to the starter. The other thing problems with the controls. turning signal work but don't blink change the flasher no change. and so on.

Let me give you a bit of history of the bike it was parked for around 10 year it came in from a farm yard. It is weather beaton I also have a parts bike too. I'm try to get it running again, last fall had it running for about 20 min. The last motorcycle I own was 1951 airel 500 twin 30 years ago the goldwing is so different from that. Thanks again. If you could think of any thing else I sure could use the help.

Rob
i changed a GL 1000 back to standard and had trouble with the blinkers ,try grounding each one individually
If the bike has been outside for ten years , i would consider inspecting the wiring on the handle bars IE the starter switch , if you are switching wiring , i would stay with the 75,76,77 -The 75 wiring would be ideal if you can source

If you can find replacement diodes, replace all four of them.

Take one out you know is good and stick it in the curcuit that isn't working to see if the problem goes away.
Does the reserve lighting stuff work?

Update
Found a broken wire on the handle bars this morning it was on the on off switch and a problem with the head light hi low beam switch. I fix them by a cleaning and a bit soider I have to reinstall the bars now.
But list night I jumped the silinode got the starter going I have spark at the points which is a good sign. I did a lot off auto electical and this had me stumped. Oh I found out the wiring harness was of a 82 Goldwing remember this is a 75 a few changes in color code. What fun to figure out. Thank for listining to my rants.

The '82 has stuff wired in that you don't have. They have electronic ignition, that runs of the rear of the crank, (I think, I hope someone will correct me on), you have points. I think the wiring to the coils is may be different, but don't quote me. My bikes are both GL1000's. A '76 and a '78. The '76 is my parts bike..

The '78 does not have the ignition and lighting diodes like the '76 does, so those circuits are gone.

On the other hand, if you don't mind doing up your own wiring diagram, you could possibly get it to fit. Just have to write down what goes to which.

Well I tried the switches that I fixed, but the starter button still doesn't work that control came form my part's bike. So I'm back to square one for awhile. I think I might sit down and airbrush flame on it so it looks fast just standing there. I guess I'm a bit teed off with the start control. Oh I do some airbushing as a hobby and I real flames.
Thanks Rob

Does some one else have a copy of the wiring diagram?
The copy I have is 556kb and we can only upload 256kb here.
Not sure I can downsize it and still have it come out readable.

Oh, you're just talking about the full schematic. It's already online here - just click on the "Manuals" link at the top of the page, and you'll see it near the top of the list - "Honda Goldwing GL1000 75-77 Color Schematic"

Rob
glad you have it running, did you find a 75 wiring harness.
Make sure you check the gas tank for rust , after sitting so long there is a good chance it requires attention
