Hi.. and welcome... i see its your first post...
A little more detail required before anyone can really offer any advice...
Are you saying you shortedcout a battery by connecting the positive and negative wires on same battery or connected the positive of one battery to the negative of the second...
And where are you measuring the voltage at to get 0...?

it shouldn't cause a problem. Current can't flow without a feed and return so touching the wires won't give the panel a return route.
the battery OR control panel couldn't be in circuit if you could touch both wires..
Are the batteries charged.?

its not sounding good for your batteries

They were fully charged ,auto electric tested it ,he seems to think it's a fuse ,.its a autotrail Cheyenne 2002

Wouldn't cause any problem except a large spark if the other terminals were connected.

Unless you touched it to give 24V, then it could be an issue
