I am checking the capacitors first, none of them have any marks of them so I'm using my multimeter to check their resistance. (I've checked online and found at least one site that says they can be tested by checking the resistance, however I found other sites that say they simply can't be tested using a standard multimeter.)
When reading the resistance of the top 4 capacitors, the leftmost three have the same reading; 18.73kΩ, however the last one reads 2.2kΩ. They all have the same markings on them, so I assumed the readings should be consistent.
Does this mean this capacitor needs replacing, or am I barking up the wrong tree?
