Tips - Bilge Pump and Float Wiring

right now we are looking at bills wiring  where the positive connection between  the bilge pump and the switch is lying  actually in the bills water notice how  the heat shrink butt connector is not  heated and therefore provides no  protection against the elements  this is serious the non heat shrink  positive wire is lying right in the  bilge wire a circuit back to the  batteries possible via the water through  the keel boats and then the shaft  through the engine and back to the  negative post of the battery sure it's a  bad run but a circuit nonetheless a  situation like this will result in lots  of corrosion on a boat it's worthwhile  to inspect the bills wiring and to make  sure that no connections are ever under  the usual level of the bills water also  we often find many heat shrink  connections not properly installed take  the time to finish those connections and  eliminate any corrosion troubles here I  am basically just slowly heating the  connection making sure that I won't stay  in one place too long and I'm also  looking or make sure the insulation is  coming out from the other side keeping  the torch always moving and this is a  good way to do a heat shrink it's a  little harder to do with just one hand  but you definitely want to go slowly and  you don't want to burn the wires you can  notice right here how there's actually  glue that came out from the back of the  insulation when it's probably tricked so  this is basically what a properly heat  shrink connection looks like Here I am  doing actually another connection this  connection was installed but actually  never heat shrink again I'm using a slow  moving action  just to make sure that it's gonna be a  popper and completely sealed connection  this will eliminate bill Cheerios are  obviously a bad place for moisture and  you want to be take away any chance for  any moisture to cause corrosion and give  you a voltage drop on the water here's  what bilge wires should look like when  it's properly done  notice that connections are much higher  than the usual bilge water levels and  all the heat shrink connections are  properly heated and therefore sealed  thanks for watching and safe boating
