    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.

    Don't the guys in Texas have a video on this I don't ever do this personally I get mine from them send back my old one get the discount whatever it is I'm not one to be doing a lot of tiny soldering and solder sucking and all that but I thought this was all sorted you buy these three or four capacitors solder them on and that's it I don't know if all of the people that are replacing these are testing everyone what they're doing I think a lot of people are just going with the flow and replacing those down there in the corner below the display portion of the board the three silver or three or four silver thing but I don't know where all the videos are.
