How do you wire a timer and relay to 19.2v drill and 12v battery?

 Can anyone help me please. I am trying to wire an electronic timer with relay to a cordless drill (19.2v) and 12v battery, and am not having much luck.  It is for my kontiki - the drill runs the propellor.  Many thanks.

Many thanks iceng - I will have a go when I can sit down and concentrate! I am abit confused - the timer I bought has one wire going to motor (drill), and +ve and -ve wires to battery. I'm not sure where the motor wire goes. I am obviously an amateur! Will keep you posted as to how I get on. Cheers.

The motor -M wire is ( you understood ) connected to the -B Battery terminal.
