Hi, can anyone let me know the best way to wire up a two motor per bogie electric locomotive to a 4QD controller. So far I have been able to get one motor per bogie running. How do I manage to get the others working. Thanks

It depends on the battery and motor voltage.

If they are all 12v or 24v wire them in parallel.

If you have 2 xx 12v batteries, you can wire the batteries in series to give 24v into the controller.

If your motors are 12v, wire the 2 on each bogie in series and then the wires from each bogie in parallel.

Make sure you set the link in the controller to the correct battery voltage.

Read the 4qd documentation, this covers motors in series and why it isn’t a good idea
