Need help with 1982 Suzuki GS650L

[steve vu]

Hi, I am working on my project bike. I need help on electronics/electrical problem. If anyone lives in Austin, texas and has a complete 1982 Suzuki GS650L. If I could meet up with you and take some pictures of the wiring diagram.

Or if anyone can send me a picture how many and which wire(s) go to the negative terminal and which one goes on the positve side.

According to the manual, there are a black and red wires go to the positive terminal. i don't want to short out the system. Any help would be highly appreciated.

Greetings and Salutations!

Hi Mr. steve vu,

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!

IIRC, I have two wires on the negative terminal. One is a big ground wire to the engine block, the other is a ground wire from the regulator/rectifier. I think I have only one red wire on the positive side. Check the 650G shop manual on my site for the stock arrangement. You'll find wiring diagrams there too.

Don't worry. There will be some real 650 owners along soon to give you the straight poop. I'm just the welcome wagon.

Thank you for your indulgence,

BassCliff

I scanned these color diagrams and gave them to Cliff to post

I don't understand why the red wire would be the grounding. Red wire usually stands positive terminal. Thanks for the diagram, much appreciated.

A PO probably used red for the ground, bad idea. I would invest in a volt ohm meter for testing, GS bikes need one of those in the toolbox.

No doubt!

Also make sure that ALL the grounds a cleaned VERY well and treated to a dose of dielectric grease when reinstalled. To that end...if you're lookiing to rid yourself of electrical gremlins, clean ALL your connectors and grease them as well.
Have you needed to do the Honda R/R yet. If not, you will. Mine functioned perfectly for about a year (6k bike when I got it) and then went wacky on me...
