The above schematic is for a twin motor/twin speed control boat with an additional lighting circuit, Battery can be a 6 or 12 volt sealed lead acid or a nicad pack.

FUSE 1 should be at least 20 amps to protect main wiring harness from short circuits.

FUSE #2 should be appropriate for the rating of the speed controls used and of the SLOW BLOW type.

SWITCH 1-2 should be a single pole ( or double pole) double throw switch of toggle type.

Most of these switches are rated to 115 volts and are more than adequate for any model using normal battery voltages.

Fuses are of the glass (or ceramic) type, 1 1/4" style. Several different fuse holders are available but the best are the clip type which screw down to a chassis with the fuse in plain view so that the condition can be easily seen.

 CHARGE JACK should be of type compatible with charger. Sockets and plugs of a suitable type are available from Radio Shack as are most of the other parts noted above.

Note that for simplicity sake, the radio wiring has been omitted. An additional battery pack, charge socket and switch may be required for this.
