Haynes manual wiring schematic is confusing the....

[Hondaboi1729]

hell out of me :( please help:

I have a Haynes manual for my motorbike and am trying to make sense of the wiring diagram but it's really annoying me why there are no legends apart from the wiring, no explanations of the tables etc,
Every paragraph is referring to the image directly above it:

1) In the above The components in the greyed out boxes the circuit symbol with parallel lines- what exactly are please and what does it do. Those things are there at the start of every wire to every component so they must be important. surely not a capacitor- why an Earth would there be a capacitor on every single wire right after every component

It just makes no sense...

2) In the above :There's also the other kind of greyed out box: The one with the circuit symbol with the
curvy arrow thing- that one doesn't look familar at all...

3) In the tables again no explanation: BAT, IG,S, W, N, The white unfilled circles with lines connecting them in the table boxes. R and L in turn signal box obviously means right and left... that's about all I can gauge in this annoying schematic. lock, free, push...

more

4) with the colour coded wires- are these the actual colours of the wires in real life?

5) Finally, and possibly most confusing of all there's a huge box with numbered terminals 1-20 and wires coming out from each. Have no idea what this box is: could someone enlighten me please?

cheers...

A multi way connector block.

2) In the above :There's also the other kind of greyed out box: The one with the circuit symbol with the curvy arrow thing- that one doesn't look familar at all...

Probably a pair of bullet connectors.

3) In the tables again no explanation: BAT, IG,S, W, N,

When the operation in the left column is active, the connections inside the switch is shown in that row. Wires are listed across the top.

4) with the colour coded wires- are these the actual colours of the wires in real life?

Colours are close, but some are striped which I can't see in your pix.

5) Finally, and possibly most confusing of all there's a huge box with numbered terminals 1-20 and wires coming out from each. Have no idea what this box is: could someone enlighten me please?

See word below the box. It is the instrument panel. The instrument panel internals will probably be shown on another diagram.

Oh for the striped I think B/G means Blue and green striped wire etc...
No other diagrams sadly :( So have no idea what 1-20 are- in the small owners manual i only count 13 functions: speedo,tacho etc... which leaves me but I'll call the honda dealer and ask...
As for the rest thank you for helping me understand :)

B is black, B/G is black with a green trace. BL or U is blue. See the color code chart.

Sweet-In the wiring diagram I don't see a spark plug anywhere- is this unusual?

I don't see a spark plug anywhere- is this unusual?

The spark plug is connected to the ignition coil, on the diagram between the oxygen sensor and injector. The engine stop switch will break the current from the battery to the ignition circuit, probably ignition coil positive. The spark plug may be shown simply as an arrow towards chassis at one end of the IGN COIL.

well you didn't show us all the circuit for your bike only bits of it so we cannot see where the spark plug is ??

Baluncore has posted a pdf file you can open and enlarge and see a circuit schematic of another motorbike ( they will all be kinda similar with just manufacturing details)
As Baluncore said, you will see the sparkplug designated as such along the lower part of the diagram just to the right of centre
