Installing the electrics.
Some people find electrics a walk in the park, whilst others struggle and have many sleepless nights. But, so long as you always follow the instructions sent with any electrical item, you cant go wrong. yes, ok its a "men thing", we , er "only look at the instructions when it dont work first time" then its time to reach for the instructions, but with electronics, one crossed wire can be disaster and can blow an electronic circuit in miliseconds! the system I fitted cam from Action Electronics and was bought as a complete package, so not only did I buy the twin motor controller [esc], but the sound system too, thats why the electrical board is quite full of bits and bobs.
1/ The twin batteries feed through a circuit board, which prevents backfeed between them, so stops any battery damage. This then supplies power to the main circuit board. This then supplies power to the motor controller, as well as then "offering" power outputs for other items, like lights/ radar motors, winches/etc.
2/ The sound system consists of the main sound controller, which then links to the amplifier and then on to the waterproof speaker. The main controller had the addition of a "switcher unit" plugged in, so I can also operate a selection of "other sounds" within the selected range of programmed sounds. So I can vary, by "flicking" the one joystick on the transmitter down, once for one sound, twice for a second........and so on up to 5. it saves having to install seperate sound boards for horn/siren/fog horns, its all built in to one panel.
3/ The dual motor controller can also be programmed, it arrives standard set for "tank steering", so assists with high speed turns by cutting the inner engine on the turn, You can alter the setting to allow for simple dropping of motor rpm's on the inner engine too, so always worth remembering. the motor power outputs then pass through a fuse panel, as a protector for both the motors in case you get a plastic bag or other debris snagged round a propeller, but also then protects the electronic motor controller from damage too from power overload.
NEVER install electrics in amodel without installing a fuse protection. a fuse costs pence to replace, once you have rectified the fault, even something as simple a a bit of plastic bag, a speed controller or motor costs a lot more and means your sailing is over, whereas removing the offending article and replacing a fuse takes a few minutes, but you are then back out sailing again.
Providing you remembered to pack a few spare fuses in your boat tool kit of course ! [ha ha].
