Sparking can be a load or dead short, what are the batteries for? With all loads turned off and all breakers on, it may spark a little initially, if it's a major spark, a huge load was left on or a dead short is in the system.
Testimonial: "The batteries are for basics inside RV such as lights, water heater, etc. I noticed the positive terminal connected to the Converter is partially melted. I removed the cable, cut the melted part out, but now the hex bolt will not tighten it in place. Do you think the bolt could have melted too?"

Loose connections consume power and this power is dissipated as heat. Heat softens metal and can disfigure it.
The mentioned bolt if defective, probably is if discolored, would need get replaced if stripped or broken.
Water heater (load) would cause a significant spark when battery is connected. Really should turn off or open the breakers or main breaker when changing this batteries connection terminals to avoid sparking, arching, carbonising and weld marks.
All electrical connections should be clean and right, check tightness (torque) at two years interval of continuous use is recommended.

Sparks occur when there is a short. It will be wise to have the breakers off to prevent any damages to other components in the RV
SOURCE: 2003 windstar no power past the battery ?
I would check with vom voltage at battery terminals and at starter to ground. Is possible could be a fuse or fusable link but I think the positive goes straight to starter and power distribution fuse or fusable link

A battery with a dead cell will not charge. Remove battery, take to Auto Zone get it checked. If battery is dead, replace with the best and biggest CCA available. Only cost $1.00 to go first class.

Many new batteries will come with bad cells from the factory. If you just purchased this, I would definately try returning it asap. As soon as you get the new one, immediately hook it up to the charger to see if you have the same results. I have heard of others who have gone through two bad (new) batteries before getting a good one.
SOURCE: Car wouldn't start, tried to charge the battery,
it has a seperate alarm ,get the side cutters out and remove it .
