A little help please? You RV maintenance veterans, feel free to chuckle...

I bought two new GC2 6 volt batteries to replace my house batteries "in kind". When installing the new ones, i got a hell of a spark when i tired to install the final cable connecting the Pos from Battery #1 to the Neg of Battery #2.

I know I am replacing the cables where they came from.

Before disconnecting, I shut off the Xantrex battery charger, I opened the in-line circuit breaker on the cable going to the battery, and I even shut down the shore power. I had no sparks when disconnecting.

completely different experience replacing the cables on the new batteries however!

What did i miss?

thanks in advance!
