I have a 97 camry.The positive battery terminal was corroded and was loose and I cleaned it and hooke up an amp to it last night.It was loose today obviously without me knowing it.The battery is good we had it tested but the car will get no power at all.we even tried to jump it.what could've hapened with the amp or a fuse getting blown. The amp is disconnected and everything.still nothing.I'd appreciate the help,thanks.

 

Amp as in stereo amp?

Did you at any time reverse the battery connections?

Do the headlights work or anything else on the car?

V6 or 4 cylinder?

 

stereo amp.
i think it backfed some power.
v6.
i think it might be relay.

 

Check all the fuses and fusible links (these are in small plastic boxes).

There is also a fuse panel behind the drivers side ash tray.
