I can see that the convert/charge you have is the SAME parallax POS that I had.
its NOT an intelligent battery charger - its a DAMN POS trickle charger that will boil your batteries dry.

the lights dim when the slide is moved because the slide motors are 12vdc - its a momentary load, done when you stop the slide - no big deal. even with the converter charging and supply voltage to the batteries - while you move the slide the lights will still dim under the slide motor load....all systems normal.

did I read this right - chassis / engine are connected to house batteries ? that shouldn't be.
I agree sounds like they tied all 7 batteries together....thats a good way to end up needing a jump start.

I wonder if someone tied the engine to the house because some batteries were weak or dead and forgot to put it back the right way?

my 12.8L motor turns over pretty quickly (not as fast as a car of course). 3 batteries should be enough to start the chassis / engine.

Im in Houston Texas - I get the bug reference.
