Wiring diagram symbols

I'm more trying to understand the significance of the dashed lines coming out of the fuses?
I understand that the charge light only needs to be live when the ignition is on and switches off when current is generated, which is why i assume
this wire is tagged with "hot in start and run". Is this why the lines are dashed and not a solid one, being a switched live?
The other two connectors go direct to the battery via some fuses. Are these dashed lines to say these are only live when the alternator is generating
current? I know technically they are live from the battery. Just more trying to understand rather than just blindly follow a diagram.
Cheers.

Just released it might be because it is fused?

I'm guessing here! The dashed line indicates that part of the circuit is shared with another cable.
The "hot in start and run" refers to +ve during engine cranking and also when engine is running.
The Wht/Blk cable from the alternator to the charge light is low (-ve) until sufficient current is generated when it becomes high (+ve).

Thanks for the reply. Sorry, if these are really dumb questions. I really want to understand why a wire goes from A to B rather than just connecting
it because the diagram says so.
Fully agree with this.

There is no convention as to why the lines are dashed its down to the person drawing. Normally it means there are alternative set-ups depending on
specification of the vehicle, but it is normally mentioned in the wiring diagram key along with abbreviations used for colours etc.

No problem, ask away. I read on here somewhere there are no dumb question only dumb answers. Talk about dumb, before I joined this site I
didn't know the difference between a tie rod and a track rod end and had never used pop rivets.

There are other wires sharing but not shown
