the best way to wire up multiple point motors
yes its me again requiring help and explanations on how to wire up multiple point motors and other multiple layout electrics.I have multiple wires going to a single terminal.I have read on this site about wiring buses could someone explain to me what it is and provide a diagram on how to make/use one? I know the basics but when it comes to more complicated things my mind goes blank.
regards

If you obtained these, I think will help you out

A bit hard to give general answers without having a plan to help us, help you.
This site is also very good

Here's a wiring bus I've just made for my new shelf layout.
It's actually two buses - one for DCC and one for DC 12 Volt power for accessories.
It's just a pair of wires connected to the track terminals of your DCC system; so you can power your rails.

If you consider your typical Peco point motor,… it has four wire terminals…two on each side. One positive and one negative for each coil. Power one side ( + & - ) and the shaft slides to that side. Power the other side and it moves back the other way. This requires four wires for each motor…you can cut it down to three !!
One way you can wire a number of these point motors would be to join the two negative wires on each point motor to a wire, which then connects to the next point motors joined negative wires and so on and so on through the chain of your point motors. This one wire that links each point motor is in effect a bus or a common wire which eventually leads back to your power source negative output.
The positive terminals on the point motors require a wire each to run back to your point motor switches in your control panel. One wire to pull the motor in one direction and the other wire to pull it in the opposite direction.
The switches should be single pole double throw momentary centre off. This means you move the switch in one direction to throw the point and when you release the switch it returns to the centre position ( off ). The same happens when you move the switch in the opposite direction. This is the momentary action which really has the switch turned off as it`s default setting.
The switch has three terminals. The centre terminal will take the positive wire from your power source. The outer two terminals will take one wire each of the positive wires from your point motor.
The switches centre terminals can be linked by a bus or common wire from the positive wire from your power source. It is rather like a daisy chain effect.
So you have one daisy chain / bus / common wire for your point motors and one daisy chain / bus /common wire for your point motor switches. One wire is positive and one wire is negative.
I hope this can be of some assitance
