Wiring up the swifty

 I am re wiring the swifty we have just got . i have power now to the new switch panel . led nav lights and anchor lights and wired up the new radio . prob i am having is i cant turn on the nav lights and anchor lights at the same time. should i be running seperate pos wires from battery to the dash or a heavy gague wire. the radio did turn on but on the screen it just said LO . havnt got as far as sounder or gps yet

sounds like your battery is knackered. Or not charged.

 never thought about that . might have to put it on charge and see how that goes. dont know how old the battery is as it was with the boat. dont even know when last had a run.

For sure looks like low power from a flat battery.

Have you also checked any fuses/breakers?

 Make sure you have a common earth from the battery. Run all your earths back to that

Negative wire

Sun, 2017-07-16 20:39

 Alot of old boats tend to use very small accessory wires.  Make sure you use appropriate size wiring.  Also, I am amazed at the number of boats that use a very small negative wire from battery to switch.  It's best to use similiar size wire to positive wire.

 

Cable size:  8 b&s should be great. Usually rated at 80amps or so. Make sure it's tinned.

 

 

Edit: oops, just re-read stevo81's reply.  Exactly what he said

 As above sounds like low

 As above sounds like low voltage. Check battery or even better get a new one if u don't know its history.  Is your new switch panel fed with the correct sized +/- cables from good connections on the battery? If so, then run your light/stereo/sounder circuits from there with correct sized fuses.

 Sounds like you are getting volt drop due to poor battery power, poor connection (high resistance joint) or small surface area of aux cable. Mandurah battery wholesalers do fair priced "all rounder" batteries that are completely sealed and have reserve charge to run an engel for a few days. an excellent choice IMO. about 240 each from memory
