I should have said that the small 6V battery was switched in parallel with the main battery once the engine started. If you are prone to leaving the lights or radio on, you can isolate the extra battery when the engine stops. Then it's hot for a roll off or to give a good spark if there is a little life left in the main battery.

So if I read you right, the small battery was charged in parallel with the starting battery but when you switched to start it was out of the circuit with the cranking battery? How did you wire the switching device?

Ray said: The other end of the jumper is connected to a poor ground on the vehicle being started, such as a bumper bracket or an accessible spot on the frame away from the starter. The objective is to use the poor ground circuit to reduce the available current and therefore provide some protection to the 6-volt system. Could you also use a short pig-tail for the negative end that is weaker? Like a smaller wire with alligator clips on both ends that you could then clip to the end of the - cable and then to the ground?

Mack, this was 1960!
I'll see if I can scan in a diagram for you.

Louis C.,
Use smaller wires only if you want to melt the wires. You could use resistor wire I suppose, but it's not really necessary.

Just follow those instructions.
