I was wondering is some of the GL100 guru’s could help out. I just got hold of a 77 Goldwing. The previous couple owners could not get it started and did not know what was wrong. They hit the start button and it dimmed the light but would not turn the starter. I tried a jump starter box to the old starter that was supposed to be bad and it popped the sprocket out and spun. I tried it straight to the starter and it turned the engine over. I knew it was electrical at that point. I have spent few weeks looking over the info for the diagrams and reading. I finally found a few wires hanging.

There were two green wires and one white/green, they were on the left side of the false tank at the forks wire harness connections.

I was able to pull the two wires out of the top of the bundle and they matched the loose ones coming from the bike wire harness. I followed them back up and they connected the left clutch.

After connecting it I tried the starter button a couple of times and it started turning over. I pulled the spark plugs and now I am getting a spark. I got daring and put car engine starter in the carb and it kicked over but sounded rough.

I have to clean the gas tanks so I had the fuel value turned off. I tried to keep running with ether can and noticed a wire got hot and smoked.

I noticed the wire before and new I would need to repair it when I get the tank off to clean it out. The wire is coming of the Rectifier on the battery cage. It is the second wire down. It is yellow. I think it runs to the ac generator.



Do I just need to fix the connections on the wire harness and rectifier or might there be another problem with the generator or rectifier?

This is what I am hoping someone could tell me or give some suggestions.

Another point is while tracking down wires and looking at things, I found that I had electronic points and I did pull them out look at them and put them back in, since I got no spark earlier. Now I am getting a spark. so they are probably off. I will try to adjust them.

Any suggestions would be greatly appreciated.

I recentlyhad an "ultimate fight" with my wiring system and sent a topic about that, how amazing it could behow the previous owners can mess up the wiring. I also had a "yellow wire" issue which resulted in my bike getting only 2 out of 3 phases from the alternator before I fixed that up.

So here is the point: the yellow wires which go out of the alternator (as you noticed) are actually the phases and there should be three of them. They go straight out of the alternator to theround shapedconnector. From that connector they go straight into the rectifier unit, which is actually abox with 6 diodeswhose role is to transform the 3 phase AC current to the DC current with only two "poles" (+ and -). Out from the rectifier unit there are two wires - green (ground, "-") and red/white (power, "+"). These two wires are multiplied later. One of the three yellow wires (phases) on its way from the round shaped connector to the rectifier is doubled so one side will go to the rectifier while the other side goes to the voltage regulator, which should be under the left-hand false tank cover. It'sa squaremetal box with ribs and there are three wires going to it - green, black and mentioned yellow.

So to make a conclusion about the yellow wires. FIRST: There must be three of them going from the alternator to the rectifier and make sure ALL the 3 are really connected to the rectifier; SECOND: There is an "offset" yellow wire which is separated out of one phase (yellow wire) after the round shaped connector and it geos to the voltage regulator. And that's it about the phase yellow wires. If any of them goes to any other place, cut it and insulate and reconnect right. BUT BE AWARE that there are more yellow wires in the wiring system which are not phases, so be careful! You will easily identify the phases as they go straight from the alternator and they are simple to connect properly.

Now as your wire is getting hot it's maybe shorted to the ground somewhere or there might be some other problem. Just check up everything and make sure that the phases are connected properly. When they are and if the wire still gets hot then you will know which wire is that and what coud be the cause (bad rectifier, bad voltage regulator, etc.) but first of all make absolutely sure that the 3phases are connected properly.

In case you don't have it I attached a coloured wiring diagram.

Good luck!

Thank you NEW OWNER. Thank you very much. A thousand thank you's. I am working on my '75 Wing and may need to do a little rewiring. Although some of the print is small I hope to be able to make enough of it out.
Sorry about your troubles WingforChrist. Can't help but will pray for you. God must be a Wing lover with all the great people on this site.

I resoldered the wires connection and got rid of the connectors at the hot points and it seems to fit. I have it running now but have to use starter fluid to get it started but it keeps going after that. it has pulled me around the yard but dies. I am going to pull the carbs and have them reworked.

The wires you found and connected sound like the clutch safe wire..IE if not connected the starter won't turn over..unless clutch in or bike in neutral.they also go to some diodes on t he left side those little reddish boxes there are four of them one is for the clutch safety switch..which you can just short out at the clutch lever..

I'd pull all the connectors in the charging circuit clean and replace..do solder the three yellow wires from the alternator or at least cut out the plug box and wire them together separately and spread the heat. Also check your ground one where the starter is grounded behind the left side engine tri mount and one at the coil mounting bracket.

Good luck
