What is the Aux Start switch for?

I had to use mine once too, when my voltage regulator died. Pain in the butt to drive holding the button.

I have since installed a new battery combiner circuit that automatically bridges the batteries on startup. However, I also need to wire in the AUX button, so I can still hold it in to manually bridge the batteries if anything happens to my voltage regulator again.

Hmmm ... why couldn't one use a special cable they easily put together ahead of time that has a male 12V plug on each end. Plug one end into a coach 12V outlet and the other end into a 12V outlet on the dash in the cab.

This setup could backfeed 10-12 amps from you coach batteries into your chassis electrical system to maybe run the motor's ignition system (no lights on, though) so you could keep moving. The same thing could be done by running the coach's built-in generator to power a charger plugged into a coach 120V AC outlet with it's output plugged into a dash 12V receptacle as you drive.

This is just brain-storming on my part - never (yet) had to try it!
