    Hey guys,

    I wanted to get some direct information on the capacitor readings I am getting now that I also took out my combo meeter due to it working intermittently.

    I tested the 3 capacitors on the far left and a bit confused on the readings. Here are the readings for each and a photo for reference.

    10uf 35v read 530
    100uf 16v read 104.6
    330uf 35v read 330.6

    So I read that the acceptable range on the capacitors is +/- 15-20% and can tell the 330 and 100 are good since they are reading at or near the acceptable range BUT the 10uf is reading way off, in the 500 range as a whole with NO decimal (unless I am reading the multimeter wrong). All read 3 numbers within their spec plus a decimal amount but the 10uf does not.

    I read that unless the readings are way off on the capacitors, they are good but curious as to whether I should still replace them or not as most videos I have seen only replace the 100uf with a 220uf 16v (which I have) and it all works again.

    Any help or link to a video where someone is actually testing the capacitors with a multimeter would greatly help. Also, I recall seeing a video (i cannot find it now) where someone also replaced other capacitors on the combo meter using the 220uf 16v capacitor but tond recall which ones.
