I dont get electrical surveys done at all, ever. there is not a used

Fresh water.

nope if the boat is used then someone has done some fixing and it
needs a total rewire. its not a corrosion issue its a people issue.
I didn't find that to be the case with mine. It was all labelled and nothing
was amis until I messed with it.

I dont usually have to much trouble but after the R/V Playboy i dont
take any chances with the electrical systems on used boats.
it took months to find the wire that was the problem the boxes and all
looked great all the connections where tight it all looked good but it
kept shorting out at randome times mostly in bad weather but at times
with a three or four foot chop. and no real swell. so i figured its
some wire in the bilge went looked cleaned it painted it white no wire
i could see.
yaddda yaddda rip out stuff finally after the whole thing goes gunny
bags in 10s with a 25 foot swell and a screaming half snow gale and
rip the entire system out.
well whatta ya know?
some time in its past someone thought it would be good to put in a
bilge alarm so they did a fantastic job of it drilling down the length
of a bulkhead stud then grooving the back side of a frame and running
the wires hidden with putty and paint all the way down to the lowest
part of the bilge. where someone else decided it didnt need a bilge
alarm and couldnt get the wire out so they just cut it off flush in
that nice dry bilge. the boat gets a bit older and she tends to get a
bit weepy from time to time that dry bilge gets a couple gallons of
water in it and shorts things out.
you would figure that this circut would be fused.
since its an alarm its wired directly into the main buss and you dont
have time to check it when your bridge goes dead you check it when you
are safe at the dock by which time the wires are all dry and the thing
works again.
