Brown
Grey
Black
Brown
Green
= 1.8k ohm +/- 0.5 %

Or

Green
Brown
Black
Grey
Brown
= 51G ohm  +/- 1%

the resistor measures "open Loop" with a multimeter

As it says on the PCB 1/2W5R  It is a 1/2 watt 5 ohm resistor (actually 5.1\$\Omega\$.)

Green = 5
Brown = 1
Black = 0
SILVER = x 0.01

Brown = 1% tolerance.

So 510 x 0.01 = 5.1\$\Omega\$
