[V8] High Current Drain

[d saad]

That is a nice looking tool!
I may have to make up one too. 

FYI, my 5-speed has never run down the battery. It usually does not sit
for more than a week, but at some point I am sure it has. Actually, it has
been sitting now for about 2 weeks and I just disconnected the cable to
pull the motor.
