Question type: Maintenance & Repair

Last week we cleaned the engine on our 2012
Toyota Corolla,  the next day my battery was dead,
I bought a new one and changed the alternator but
today it's dead again. When testing the amps
something is running but how do I figure out what
amd how to fix it?

With your amp checker in place start removing and reinstalling the fuses one by one until you see a sharp drop in the amp tester. Then you'll know what circuit is drawing the excess current. Hope that helps! Jim

How did you clean the engine? Pressure washer? Hose and bucket? Chemical spray? Any method my leave you with wet electronics or other electrical problems. You may still have to do the Ammeter-fuse testing but just letting the car dry out may also work.
