Yellow/Black Wire help

[Matchless]

Good call Andre! Although it does appear to be coming from the harness rather than the R/R... bit hard to tell for sure though.

AFAIK Suzuki does not have any Black/Yellow wires with large ring teminals. Maybe someone replaced a Black/White tail to ground lug (which are prone to melting) with a bit of Black/Yellow.
The only way to determine this is to remove the insulation tape and trace it back and see if it connects to the main Black/White ground in the harness. If you are lucky you will only have to trace it back a short way.

Other Black/Yellow wires on a GS are as previously mentioned, ignitor to coil and tach(with electronic tach) and fuel level sensor to gauge. Other models may have used it somewhere else as well.

no its coming from the harness. it goes to ground but so do the positive and negative wires.... im just not sure where it bolts back onto because my dad unhooked those wires when we were removing the battery

If you know for sure that it's a ground lug, then it just needs to go somewhere it'll get a good ground.

Try either the R/R where its ground lug is or on one of the starter solenoid bolts. The actual bolting point for ground connections is only important in terms of if it gets a good ground or not.

I put as many as I can onto one bolt with a known good ground connection, and my whole electrics tray is now grounded also as I made it from galvanised steel (that's one of the starter solenoid bolts):
