There should only be one wire on the right hand post. That would be the + wire to your starter. The rest of the wires should be on the same post as the Battery + cable. Off the top of my head, Id say those yellow wires are shorting out when you hit the key to start. Make sure they are not shorted out somewhere before you hook them to the + post though. Also, make sure the little metal box is not shorting out against sometning. It's the circuit breaker for your door locks.
