I'm only getting 10.5 Volts. Is that normal? Seems like a big voltage drop? Ironic it's so close physically to the battery but I guess so far away via the fuse box...

Poor earth connection or resistance somewhere in the live feed. Take a reading at the bullet connectors in the boot for starters.

If you don't have a headlamp relay the current draw through the switch can pull the voltage down on all the lights. Worth adding one... ;)
