CTEK Multi XS 4003 battery charger R26 resistor value?

Have had a resistor in position R26 on the pcb blow on an otherwise good CTEK Multi XS 4003 charger. The bands are so discolored that I am unable to identify its resistance. Looks like a 1W capacity. Can someone please help me with the details I require. The manufacturer has declined to repair or assist with the information required.
There is bound to be someone who has looked at one of these units. Thank you in advance.
