Electric wiring question

Robert E Morey · Post by **Robert E Morey** » Sun Jul 12, 2009 2:12 am

Hi all,
I am trying to wire and run my Panther hull with just the main motors. From the schematic it looks likes all I need are the main motors, the VTX40 speed controllers, the DMR203 switch, a matched receiver and radio and a 4.8V battery.

I'm confused where the 4.8V battery plugs in. The schematic shows it plugged in to the receiver, but also wires or lines going from the 4.8V into the switch box? How is this possible? Are there two 4.8V needed? One for receiver and one for the switch box? The switch box has a plug that the 4.8V can plug into? Does the battery plug into the receiver? switch box? or does it matter?

Is there more needed to drive the hull around on just the main motors (no sound, no turret rotation, gun elevation etc)?

Is there any way to eliminate the need for the 4.8V battery all together?

Im using a standard futaba skysport 4 channel radio and receiver.

Any suggestions would be appreciated, thanks.
Bob

Hi Bob,the battery plugs into a wire/plug from the fuse box.Not the recvier.
there's a plug that does go into the reciver,it has a r/c plug.I think it comes from the fuse box too? Dan

Bob
It does matter there the batteries plug into.Armortek has it right.I done it with just the main motors before.
from the fuse box there are two wires with different plugs on them.1 goes to the battery and the other to the receiver.
I don't know if you can remove the 4.8 battery.
But on the newer systems they don't use the 4.8 battery.
I hope this helps,and is clear.

Bob, looking at the schematic, it looks like the battery should plug into the switch box and then the lead from the switch box goes to the receiver.

In this way, the 4.8v battery is disconnected when the tank is turned off, thus saving it from being drained by the receiver.

I did find on my Sherman that the socket on the lead from the switch box didn't fit my Futaba receiver battery, which had a small ridge on one side to prevent it from being plugged in the wrong way round, so if you do have to remove that, be careful which way round you plug the battery in

Thanks guys, your advice makes since. Adrian you're right one must not reverse the polarity of the 4.8V. I found too that both the 4.8V and radio battery were not taking a charge and were probably dead. These batteries do have a limited life and are over 3 years old. So new batteries are on the way. Hopefully do another drive test on Wednesday! Cant wait!
