GS850 Suzuki 1981 Electrical Problems
HTML-код
- Опубликовано: 5 сен 2024
- Working for a while on an 81 GS850. Runs great. However, it has the electrical problems that many of these bikes encountered.
Replaced the stator and it pushes 79v each leg perfectly. Installed a Polaris R/R on advice from the GS experts. It is good.
I routed the stator directly to the R/R and had the R/R Pos lead connected directly to the Red Loom wire like original per advice. Also, connected the R/R Neg to a SPG (single point ground) along with a lead to the battery box bolt and a lead to the battery Neg.
The bike still did not want to charge sufficiently. So now this video shows some troubleshooting in my journey. The bike did finally charge, but it is not wired correctly. Any answers or suggestions, have at it!
Please note, I am an electrical NOVICE. If you reply with a technical answer, you may have to use short, simple terms, that we beginners understand. :-)
And my apologies for some of the camera angles... And finally:
KUDOS to all the guys from thegsresources.com website. Steve, Jim and others, I would not be this far without your input!! THANKS!!!!!!
I love the bike, i got a GS 450 and i love it ;) Thank you for the video
Thanks for video... GS resources great guys, very helpful....
Thanks. They are.
Just tore the top end and base off today. Got new head and cams from GS guy. BIG help again. Having the head redone, cylinders honed, and engine bead blasted. Not going to be a show bike, but I hope to ride it to Sturgis rather than my Harley. :-)
great video .. cheers
Would the stator, rectifier also cause issues with the headlight? My battery dies and the headlights dont work on my gs650g 1982
Shout it to Steve and Ohio for sure!
This made me a little crazy. Did you figure out why the black ground wire from the battery ground caused it NOT to charge? That made absolutely no sense to me.
connect an earth wire from rectifier earth poit to the negative on battery
I have a 1980 gs1000e and I have some serious issues. I am just not getting any power whatsoever. How could I ask you for help?
First, Thanks for viewing. Will try to help. I always direct everyone to go to the GS website: thegsresources.com/
Also: members.dslextreme.com/users/bikecliff/
Do as much reading on this site as possible. It will help you know your bike.
MUST READ: members.dslextreme.com/users/bikecliff/images/GSR_Greeting.html
This last link will tell you the 10 must repairs for the GS bike. I've done all of them except the Stator change.
You say not getting any power... Questions:
How many miles are on the bike? How long have you owned it? So it starts, but doesn't move? Have the carbs been touched?
Look at that list of 10 issues to deal with and tell me how many may be an issue.
Hope that start helps.
Hi, may you please make a video about how to raplace all the points system for this bike? Thanks
Victor, I know your post is old but I was not getting notices.
Anyone who needs expert help with these Suzuki bikes needs to log onto the GS site:

Good luck.
hey i have an 1981 gs750L an it jus tkile dout the other day on me motor is in great conditon i replaced the plugs coils an stator but it still wont get a spark an im no expert.

thegsresources.com
You should get account and log on.
Good luck.
So what have you concluded is your problem...have you fixed your poblem...
I’ve almost finished this project. The website thegsresources.com and guys associated with it provide huge help.
Mainly there is a list of 10 issues to address when restoring these bikes. And of course making them road reliable.
I highly recommend the advice from that site.
I've been having a problem with mine it's a 65 gs 550 keeps blowing fuses or just diving and won't crank or start by clutch pop have any Ideas what's wrong? I can't figure it out
Dieing not driving
Hey Josh, admittedly, electrical problems are difficult for most of us. That said, first Google how to do an electrical check on your bike or similar. They are mostly alike. Motor turns the stator, stator produces a charge, sends to regulator, which in turn dials down the charge to be used throughout the bike. Have a good volt meter and make sure the stator is producing correctly. Then test the regulator. And the battery.
Also, go to www.thegsresources.com website. Search the threads for your model. There are guys on there who have fixed them and there's a lot of knowledgeable guys there willing to help.
And perhaps the best site of all is found here:
members.dslextreme.com/users/bikecliff/
There is a manual for your bike. And the guy who runs the site is a GS god... yes, god. Good luck.
Doug Fresh thanks bud appreciate your help
Did you have to free pistons for restore?
Sorry about late reply. Wasn't getting RUclips notices.
No. The motor was in pretty good shape. All the usual problems of the GS needed attention. There is a list of items you must address on these bikes to make them run right and reliable. Here is a link to the GS bike website. A lot of info that will help you.

There is a guy who will rebuild the carbs very reasonable if you ship him the set.
Dont know the reason why ? but there is definately a reluctance with owners of old bikes like these NOT to replace old worn items like this for new, i have the identical model colour, year bike to this one if id gotten charging issues with it id have bought a NEW genuine suzuki regulator/rectifier unit for it, items like this are STILL available new from Suzuki nothing lasts for ever !,
i wouldent say these bikes suffer from electrical gremlins , NOTHING lasts forever regulator rectifier units are popular for failing and going faulty on old bikes these are all 38 years old now cant help thinking you'd have saved an awful lot of time and effort there by just buying a brand new genuine Suzuki unit for it ,
Sorry about late reply... However my reply is a quote from the GS Resources Website. Managed and attended by guys who know these bikes as good as anyone in the World.
"There is one serious problem that probably affects all GS models: the charging system. This problem, usually ascribed to the stator, is in fact caused by the regulator/rectifier. You can read more about this in "The Stator Papers".
This problem is so serious and so devastating that it contributes greatly to the GS having a very bad name as far as electrics is concerned -- as someone said "with an electrical system so bad that it makes a Yugo look good".
You may want to look at the sight.

@@dougfresh1341 so did you then replace your rectifier with a factory one to cure your problem...
would be cool if we could see what you are talking about and not a close up of your seat.
