will a battery short out if the wires touch aluminum?

Yes if both pos and neg come undone and both touch aluminum.

seems like someone fell asleep in the chemistry class


do it - experiment yourself !!!
fasten the negative to a piece of scrap aluminum,
or any other metal, and very quickly drag
the positive wire across it.
THEN - you will know the reaction first hand.

and notice I said "scrap metal" - not on your boat hull.
and, IMHO, a quick test will not harm your battery. (QUICK test).


I, for one, would like to know your results.

How much taxpayer money is spent on public education only to have this question come up ](*,)


On a more useful note, that is why you are always recommended to have your fuses as close to the battery as possible.
I have a marriage license and a fishing license, but I only carry one in my wallet.

please don't try this

we don't want someone blowing up a battery and injuring themselves.

Just take our word for it.

When I was a teen (just started driving) I had my trolling motor battery in the back of my truck. Had to slam on the brakes and the battery slid up under my toolbox. Not a pretty sight. The terminals got wedged under the tool box and caught a roll of paper towels on fire.

Anyway, to answer your question, YES. If you connect a 10ft wire to positive and a 10ft wire to negative, then touch it to a piece of aluminum, its no different than touching the two tires together, or laying wrench across the terminals.

aw come on Perch - weren't you young at one time or another ?
did you always take the advice of others ?
a quick arc of the wires on metal will not blow up a battery.
some loss of feeling in the fingertips after the blisters heal, maybe.
but the battery won't blow up.
EXPERIENCE is the best teacher !!!

If the wires are creating a short somewhere and there is no fuse to stop it they can get extremely hot. They can get hot enough to burn through flesh in a heartbeat. The wires will be acting as the fuse and it may take a lot of heat before they burn themselves out depending on the wire size. The larger the wire the hotter they will get before burning out. I have seen wires get so hot they char the whole length of the wire and turn the insulation to ash in an instant.
