1983 GS650L (GLD?) Wiring Diagram

[thadoublej]

Anyone know where I can download one? I have a wiring connector that's smoking and melting under the tank, not sure where to start troubleshooting.

Welcome, check this site out for the service manual and wiring diagrams. Basscliff will be along later with the official welcome.

Greetings and Salutations!!

Hi Mr. thadoublej,

Start by checking, cleaning, repairing, and replacing (as necessary) EVERY electrical connection and ground on the entire wiring harness from inside the headlight bucket, connections on the ignition switch, the fuse box, the battery and solenoid terminals, the charging system, all the way to the tail light and blinker stalks. Your bike will love you for it.

Anyway, let me dump a TON if information on you and share some GS lovin'.

I just stopped by to welcome you to the forum in my own, special way.

If there's anything you'd like to know about the Suzuki GS model bikes, and most others actually, you've come to the right place. There's a lot of knowledge and experience here in the community. Come on in and let me say "HOoooowwwDY!"....

Here is your very own magical, mystical, mythical, mind-expanding "mega-welcome". Please take notice of the "Top 10 Common Issues", "Top 15 Tips For GS Happiness", the Carb Cleanup Series, and the Stator Papers. All of these tasks must be addressed in order to have a safe, reliable machine. Now let me roll out the welcome mat for you...



Please click here for your mega-welcome, chock full of tips, suggestions, links to vendors, and other information. Then feel free to visit my little BikeCliff website where I've been collecting the wisdom of this generous community. Don't forget, we like pictures! Not you, your bike!

Thanks for joining us. Keep us informed.

Thank you for your indulgence,

BassCliff

Yes, head to Basscliff's tower of knowledge. Hopefully, you've already removed tank to investigate, cuz this is not a good place to deal with flames. Give us some bike history and maybe a pic.

Most likely the white/green and/or white/red stator wire cooked. Very common problem, and avoidable if you read up around here. Unfortunately, most people don't know what to do until it's too late.

I checked out both diagrams for the 83 GS650, and both make reference to a gear indicator light that I don't seem to have. What I do have is a connector with Y/G, O/G, W/G, W/R, O/W, and Y/W going in, two jumpers (that are melted now), and Y/W, Y/G, O/W, and O coming out. Connector is dead center, underneath the tank, and so melted I can't get it apart.

Ok, here's history and pics. Found this sitting under a tree, not running, but complete. Gave 150 for it, found that someone had tried to seal the carbs with silicone, dissasembled em, dipped em, put a battery in, cut off, unbolted, and threw away all the parts that were shiny. Got her running pretty good, parasitic draw somewhere that I haven't gone looking for, then she sat again for a couple years and mucked up the carbs again. Cleaned em, haven't dipped em, got a flat spot in the middle that I'm hoping will work it's way out with some riding, but now this small electrical issue. Here's pics of the bike before and after, and of the troublesome connector.

Under a tree and $150- hmm, not bad! look just behind gear shift lever pivot- do you have a plug with wiring coming out of it? This is the gizmo that decides which gear you're in and reports to dash lights.

[thadoublej]

I still can't figure out what this connector is to/from. Maybe I'm just reading the diagram wrong, but does anyone have any ideas?

The stator wire cooked the connector like already suggested. That connector goes to the LH hand control.

I suggest you rewire your stator to feed direct into the R/R and cut out that extra wiring (the wiring diagram details what I'm saying so please check for yourself).

You also might want to improve the R/R grounding situation since that is what most likely lead to the wire overheating.

This is (sadly) a common GS problem area. There are lots of different threads in the archives detailing how to go about repairs.

[thadoublej]

I think I'm confused again. The stator is the generator? I can see a wire from the generator (on the diagram) that seems to run all over the place and come right back to the R/R. This is the one I need to eliminate? My wiring harness has two jumpers in it though, both seem melty, do I need to track down and elimate all the wire from both of them?

[Nessism]

Yes, the stator is part of what Suzuki calls the "generator". It's located under the LH engine cover, behind the stick on badge. Three wires come out from under the engine cover and route somewhere in the vicinity of the starter motor and plug into the main harness there. I suggest you find the stator harness bundle (three wires) and disconnect them from the main harness (Suzuki used bullet connectors).

Now physically find your R/R and take note of how it ties into the harness. R/R's typically have five wires: three inputs (from the stator), a positive out, and a ground. What I suggest is for you to physically join the three stator wires with the three R/R input wires. Either solder the wires direct or use crimp on terminals of some sort. You also need to make sure the ground is clean and secure. It's best to add a supplemental ground going direct from the R/R to the battery negative terminal. The positive out wire can connect back into the main harness as designed. The power goes though the fusebox and over to the battery.

You can leave the old wires in the harness, they won't hurt anything. That melted connector needs to be cleaned up, but you don't have to worry about those White/Red or White/Green wires since that is the stator wire leg that you already bypassed.

Good luck

Well hooray guys, big thanks to everyone that helped me out on this one. Tracked down the three wires from the stator, all black of course, two of them looped around back into the RR, the other one went through a terribly corroded boolit connector, up to my melty connector, then back down to where it should be. I popped the spade out of one connector, soldered a spade in place of the bad boolit, and then clipped the ground for the RR off the bottom of the battery box and attached it directly to batt ground. Ran the bike for ten minutes or so, popped the tank, connector is cool as could be. Still need replace the melty connector, but I ran out of terminals. Looks like as soon as I get these carbs working right, she'll be back on the road.
