ground wires
i have a 1982 GS 750 with 2 black and white wires with loop ends leading out of the wiring harness. One originally went to the starter solenoid and the other to the battery box . Is it best to run these 2 wires to negatve post on battery or leave them as the factory had them?Tags: None

If you connect them both to the battery your bike will not charge at all.
You should at least reconnect them to where they were but prefereably..............

STEP #2.) GOOD R/R GROUNDS Make sure that the R/R(-) is properly grounded to: harness,battery,frame.
I have described a single point grounding approach that minimizes the amount of current that flows between the battery (-) and the R/R (-) connections. By doing that there is less susceptibility to resistance due to bad connections and corrosion and the R/R should charge the battery more accurately.
While there a different ways to implement the R/R grounding scheme, the way Suzuki originally implemented the GS electrical charging systems is confused, inconsistent and not ideal in any sense of the word. I provided the theory of why the one below is best, I will not rehash that here. Just follow the directions below:
By picking one of the R/R mounting bolts as the single point ground point, the R/R(-) wire can be very short, the mounting plate is automatically grounded and all of the return current wires can be tied securely together at a single point. Here are the connections- #1: Ground R/R(-) to case and side plate
- #2: The shortest wire to a frame bolt
- #3: The shortest wire to the Battery (-)
- #4: Connects to the (B/W) harness negative ring lugs (typically the one attached at the solenoid mounting bolt). You can leave the other harness ground ring lug (B/W) where it normally is picking up the battery box ground.
