When Bert relocated the water tank to outside under the coach (no, did not
use the existing one, made a stainless tank to fit the location), he also
relocated the water pump to under drawers in the kitchen. Due to this, he
then ran a new hot wire to a switch that he installed in the electrical
compartment inside the coach. While this works, it is mighty inconvenient
to use and since I have the oven out along with the ceiling, I thought it
would be a good time to run the wire over head and connect to the existing
on from the switch at the doorway.
However, that wire appears to run up towards the ceiling and then towards
the back of the coach before returning back down behind the bath unit. If I
could find that wire at the top of it's run, it would be easy to connect
onto it there. Short of pulling the refrigerator out, that doesn't appear
to be possible, unless someone else has a solution. So, I figured that I
would just run a wire up over the ceiling and back down to the existing
wire and splice it in. While looking at the 12 v wiring diagram for 1975
-1976 coaches and following the wire from the pump to the switch, it shows
a 10 g wire going through an inline fuse at pump to a square box with a 2
in it and then becoming a 12 g wire, which then goes through another square
boa with a 2 and then on to the switch.
Hence the questions: are these boxes connection points and would I be
correct in downsizing the wire from 14g to 12g? And, is an inline fuse
needed at the pump (don't have one now) and if so, what amp?
Again, thanks in advance for the help
