tachometer failure?

my 93 accord has been running fine but suddenly my radi started losing power then my tachometer and speedometer failed and my abs light flickered on and off and lost most of my driving power? checked alternator tested fine battery replaced and yet i turn on the ac and it does it all over again now my battery is dead but alternator tested fine the night before wtf?

Wow! If it were a horse, I'd shoot it!

Sorry - gotta have a little levity here once in a while.

The mention of turning on the AC makes me wonder whether you have a problem in that area (compressor circuitry etc). I would think it would blow a fuse sooner than cause all the rest of the electrics to fail, but ----- ??

How long have you had the car? Could a previous owner have used aluminum foil instead of fuses? (sounds dumb, but people do it).

checked fuses didnt look like any blew but now my battery is dead and today it would stop acting up if i turned off the ac?

im having a similar problem but it's my spedometer and my odometer not even flinching while im driving but everything else works does anybody know sumtin
