The dead battery thread got me thinking about this...

I did a search and saw a few comments, but they were about running a 12V battery permanently on the same starter and 12V coil.

Who here has had a dead battery, and got a jump start from a passerby 12V good Samaritan? Did anything smoke or fail?

If you keep the 6V battery in the circuit, it will act as a bit of a buffer on the 12 volts I'd think.

My car has a messed up crank pulley, the crank just won't engage without slipping. I can't start the car by hand. I didn't find this out until the car was together, and the engine rebuilder didn't catch it either. (!)

So I haven't needed to yet, but what say you if I'm on the road and need a jump start and there's no downhill in sight?
