I have a CTEK MXS 7.0 which died. Resistor R1 has burnt out so I can't see all of the coloured rings and was wondering if someone on here new the value. The first ring is yellow, second is totally burnt, 3rd might possibly be black (but can't be sure) then 4th and 5th are gold. If 3rd ring is definitely black then I know it's likely to be 40, 43 or 47 Ohms. Hoping someone can confirm please?
