1990 Honda Accord Lx Antenna Problem .

My car won't start after metal touching positive post and it smoked. Could it just be the battery or something else?

First check all your fuse’s , yes every last one of them , most cars have a large fuse panel under the hood as well as in the passenger compartment, An then you also have what's called a “ Fusible Link “ , These are normally located going to High Amp Circuits , in your car , i.e. The starter , the alt , the fuse panels , Modern Cars have dozens of these Fusible Links , An they have different ratings that depends on the wire size going to that Component ( I think there are about 6 different gauges / sizes ). What happens when in your case a Direct Short , occurs it protects the wiring An various other electric components in your car ,, they melt down when large amounts of current pass thru them , most are covered in a Fire Resistance shrink tubing type material, An they are soldered on to the wiring of the various components , So grab your self a VOM Tester , or a Test Light use one for Computer Circuits - The VOM Meter would be a better choice , An starting looking for where there is no power where there should be power going , There's a old joke We Mechanics have - wires carry smoke thru them An when you let the smoke out there no good anymore, Good Luck , An hey don't let anymore smoke outta them wires , oh An if you find out it is a fusible link - don't let the Clown at the parts store try An sell you a 25 foot roll of it , tell them you only need like a foot ( 12 inches ) of it OK , An if they tell you otherwise go to another parts store as they are idiots ,
