Default Connecting to battery terminals? (without ruining)

There are two things you could do.

1) Buy a small DC barrel female plug and open up the machine, splice it
into the power wires, drill a hole through it and mount it. After that you
can just plug the adaptor straight into the machine.


A fuse might be a wise addition. That's certainly the proper way to do it if
it must be done though, provided the power adaptor is up to the job and
suitable for the purpose.

2. Get 4 D cells that are discharged. Solder a the positive wire from the
wall wart to the positive terminal of one of the batteries, the negative
to another battery, and the other two remaining batteries will simply be
used to hold everything in place. After that, I would just put some
electrical tape in between a battery-to-battery contact to avoid
accidently recharging the batteries.



You're kidding, right? I wouldn't let my kids in the same room as that
arrangement. It only takes a tiny breach in the tape for a potentially
serious accident to occur. It's a time bomb, especially around kids.
