I've got a similar cognitive quirk that works to may advantage as well.
When working with a machine, device or system I can't take apart I can mentally visualize the theoretical and most likely internal details and layout of how it is put together or works based primarily on visual observations of the external layout which is a highly right brain ability.
Then from there I can break down the theoretical assemblies and do an analytical by the numbers troubleshooting procedure from that.
Still can't spell worth a darn without help though.
