Glad its working right.
I have to admit to never having had a real Bobs board and working on general principles- being a cheapskate and having an etching kit I built my own and used resistors rather than guesstimating the resistance of the etched tracks. That way I got the right values for my motor.
The principles for colour coding that are good now were just as valid back then - battery wiring should be red and black, motor (or whatever load) should be some other colours. Any manufacturer or designer using all red and black should be taken round the back of the bike shed and given a good kicking (just a theory to encourage good practice).
My home made one didn't short the motor, but that was a sound idea for the Bobs board - it gave something to line up on and at the same time ensured that the moor, at neutral, would STOP.
