There is some logic to what you have show here.

I'd stay with the two separate 10amp fuses for the playfield lights since they are separated into two circuits.

Also, the schematic indicates there may be two reset bank coils so each one should have its own 1amp slow blow fuse if there are two reset coils. If not, there will only be a holder for that one.

7.5 slow blow for the main is presented consistently.

10amp for the head lights is consistent also.

I think you will be able to get these defined by elimination.

The 7.5 amp on the primary should be slow blow.

Looking at the interior photo on IPDB there are two reset banks on the main relay board so you should have have two reset coils and two separate 1A slo blo fuses, one for each. Look near each coil for its fuse.

Lighting is always fast blo.

Follow the wires off each of the reset bank reset coils. It should be directly in line with one of those wires very close to the coil.

I thought we had acknowledged that in post #3.

I'm surprised another SkyLine owner has not opened up their game and chimed in on how theirs is set up, if nothing more than to confirm this is how they got built and that yours is not a one off.

Gottlieb schematics are usually pretty accurate but this would not be the first time they did not reflect 100% how a game is set up.

High tapping does not justify increasing fuse values. Where your fuses are above the specified value you are highly recommended to replace them with the correct size.

I'm sure Donal knew the need to fuse game circuits properly and he probably never looked at those fuses. Someone before him must have oversized a few of them. Replace that 15amp fuse on the fuse board with a 10 amp fast blow. 1 amp slow blow should be correct for the reset bank coils, not 10 amp fast. I would have no problem leaving the 5 amp on the main if it has survived all these years but 7.5 is what shows on my Kings and Queens schematic for this fuse just like the Sky Line schematic posted above shows.

Under fusing is not a problem unless you find it blows because it is undersized. Over fusing has the potential to let something burn on the game.
