A regulator would draw current when connected to power.
It may be drawing low current but +5v is still being provided.
505 go back and see where the 8v begins.
Marker light wire as in speedo/tail light/license plate light?? Black/Brown wire in the front, solid Brown to the bullet terminals in the right side cover.
Oxidation in a wire terminal could cause the voltage drop.
Check for battery voltage at the fuse, one side faces Ignition switch/battery the other side the load.
Some USB power ports provide 1/2 amp +5v (Usually older ones) Late model devices show a message about a low charging current.
Most new USB provide 1 to 2 amps +5v
