Re: wiring up my boat with lights and pump and accessories
There are more good ways to go. Sometimes you have to adjust the original plan along the way.<br /><br />Equipment designed for marine use should be chosen.<br /><br />One simple way is to have a (quite heavy) wire from the battery positive to a bank of fuses - feeding 'em all. Then connect each device positive to a fuse on the bank, preferably via a switch. The negative wires from the devices can be connected to a common.<br /><br />If you want to install advanced gear that controls each other by corresponding power and relays, some additional wiring (diodes) may be needed.<br /><br />There are battery managing devices, that separates a starting battery from another (for all other devices) while engine is not running. Once running (charging) it first charges the starting battery and then charges the next. This way your starting battery is always first priority and protected from discharge.
