Hercules - Section 12 Electrics

Electrics The wires from the control board to the batteries must be of at least 6mm². Anything less will cause overheating and even the possibility of fire. If you intend to run the loco excesively hard then it may be worth investing in 10mm² wire for the battery leads. If you are using the iDrive controller then the motor leads should be long enough to reach the controller directly. Connection is via a 6mm ring crimp. On the motor leads pair up the black wire from one motor with the orange wire from the other then the orange from the first to the black of the second motor. Which ever style connector you use make sure no bare wire is exposed which could come in to contact with the chassis / bogie. Wires should be tied back to keep them away from any moving parts.

IMPORTANT. 6mm wire is not designed for 120amp but can cope with it for short duration's. The wire should be left in exposed locations to allow for cooling. Do not tape wires together or run then in conduits or they may overheat.

For the standard Hercules the control board is mounted flat on the deck with the motor wires coming up through the deck via the supplied plastic cable glands. The picture below shows the Hercules with removable bogies. This is why the control board is mounted on angle iron in the vertical position.



With the iDrive controller mounted flat on the deck it is possible to get the motor leads to the control board with out extending them. On the motors leads pair up the wores fropm each bogie and use two crimps per connection. This way if a bogie runs the wrong way on test you can simply swap the wires around. MPORTANT. Please please please triple check that you have the battery terminals the right way around. If you do not have colour wire then use coloured tape to mark the terminals. Battery leads should be tied so they cannot be put on the wrong terminals. This is especially important with the link wire.
Note the battery isolator is spaced off of the control plate via nuts on a 40mm bolt. This is so the key clears the bodywork and is why the hole in the plate is not big enough to slide the switch all the way in. (had to say that as I have been told dozens of times that the hole is not big enough).
		This chassis is for the Hercules with removable bogies so the controller is mounted vertically to make space for the bogie plugs. Mounting the plate as per the picture to the left, lines the battery isolator switch up with the windows of the Hercules cab. It is tricky to turn it on and off but it does remove the need to take the body off every time you need to turn it on/off.
