Hi! all.
........and for my contribution ...use multicore welding wire! On short runs
the weight factor is negligible. Been there got the "T" shirt.

up to 70 amps. If you pull more look for a problem. Use 4ga. wire even a
2ga. for a long run. The shorter the battery to starter wire the better.
Make sure the ground wire is a larger size too.

I agree. The impedance of the motor is very low until it starts to turn at
