That's what's threw me the previous owner has had an extra ground from the starter to the battery but I couldn't think whyComment
-
So the wire from the starter solenoid and the 2 B/W wires from the loom can all go on the battery negative??Comment

The ones from the loom are likely meant to pick up other parts on the chassis such as battery box etc but as a general rule as long as you have a ground path to everything and all black /white is connected to ground you will be ok.
I think it's a weather thing... with the corrosion rates in our part of the world (UK & Ireland) I think that's something that gets drummed into you early! Of course you shouldn't need extra but a bit of redundancy helps in that locale.1980 GS1000G - Sold

Looking at the picture Grim put on here. There's no wire connected to the Neg. side of the batt... Wondering, can you call all those wires grounds?, or are they just wires connected to the frame? No doubt will be grounds when batt. neg. is connected to the frame but until then they aren't grounding anything... or are they?1983 GS1100E, 1983 CB1100F, 1991 GSX1100G, 1996 Kaw.

The battery in the photo is a MOTOBATT. It has 2 positive terminals and 2 negative terminals on each side, unlike other batteries that only have 1 of each. So the terminal on the right hand side in his photo that does not have a wire connected, is actually a "spare" positive terminal.
Remember the extensive "Single Point Ground" (SPG) discussions by Posplayr (Jim) a few years ago? Well worth reviewing again!.1981 GS850G "Blue Magic" (Bike Of The Month April 2009)

Thanks 2B, I've used Motobatt batteries a couple of times but never knew they, or anybody else, made some with 2 neg. and 2 Pos. terminals. I did wonder about that red plug on what I thought was the Neg. terminal but just thought somebody poked it in there.1983 GS1100E, 1983 CB1100F, 1991 GSX1100G, 1996 Kaw.
