    I got a couple of these Harbor Freight cheapies for free and the ohms function is not working, accidentally connected them to a hot circuit. Fuse & batteries ok, and other functions (dcv and acv) work ok. Anybody have a schematic or know if anything other than the main IC might be the problem? No sign of anything burnt.

    Is it really worth your time.. You likely damaged some IC.. It will cost you FAR more in time/money to repair it vs just getting another.

    I'm all for fixing something if you can and if its worth it.. I could never justify fixing Harbor Freight junk..

    Allen,

    Thanks! I think it's close enough. Chip on HF dvm is blacked out, but this will get me in the ballpark.
