Wiring Symbols

I have been working through the wiring problems on my 79 KZ650 and have been able to work out what most of the symbols are.

Can anyone tell me what the double circle connections mean on the attached wiring diagram? Is the connection meant to be earthed to the frame??

Cheers everyone.

I have now attached an image of part of the diagram - apologies for the low resolution...

The connections are two circles connecting a wire.

Help please...

Depicts frame ground....

Your wiring diagram should also have a symbol chart/identifier such as this on mine....

OMR

If you look closely OMR, one of those is on the positive side of the battery. Note, its on both poles of the battery, both sides of the starter relay, and all 4 signal light grounds. I'd be inclined to say it just indicates a bolted connection with the wire going into terminal rings.

Good point T...

I was actually referring to as in my diagram the designation chart reference being on his wiring diagram...

Could also depict a bolted/screwed termination but don't have his drawing...

Then there's always as we have found in numerous OEM drawings... errors...

Yeah, I'd say as long as the wires are connected to the correct places, you're good to go. I don't think they had any frame grounds mid line, so I just treat all the circles and arrows the same. As long as the wires are connected to their buddies you're good to go.

I didn't realize you were talking about yours lol.

The battery in most motorcycles is connected to the frame (usually on an engine mounting bolt)from the BLACK or NEGATIVE(-) terminal.

Kawasaki in it's infinite wisdom may have decided to add additional grounding areas for redundency.

In some electrical circuits this could induce a "Ground Loop" creating a "Hum" in audio devices.

I don't see it causing any problems in motorcycle use.

They usually represent a bolt connection, but not necessarily ground.

You can have as many ground points on the engine or frame as you want, as long as they are good connections. It's when they get dirty or become disconnected that wierd problems will show up. It's better to rely on actual ground wires for everything then tie the ground wire to the frame and then to the engine right where the battery negative cable ataches to the engine. The reason you want to have the negative battery cable go to the engine is because the starter uses the engine as ground.

My experience is that those circles indicate a "bullet" connector where the harness can be unplugged from the device.

Frame ground is indicated by a line with three angled lines coming from the line and the wiring coming from the other side of the line.

Thanks for the posts.

NONB, I think you are correct as there are frame grounds depicted as you say elsewhere in the diagram. I will go with a bullet connector idea and see where it leads me...

These circled connections are for the heavy battery cables. Obviously they are not bullet connectors. They are bolts. The one by the marker light is probably the ground point (bolt) as the light may be a one-wire light. Notice the other one on the starter motor. Obviously the starter cable is not held with a bullet either. It is a bolt. (T-dub already mentioned all of this, by the way. Even in OMR's photo, the circle is a bolt holding the ground connection.)
