I started trying to chase a couple wires because of some Gremlins my boat has, and uncovered some bird's nests or as some of you call Italian Wiring (spaghetii) under the dash and behind the side panels, so I ripped everything out and am going to start from scratch. Furthermore, i hated having seven wires hooked to each post on the battery. I looked at some past threads on here of some real clean work (squirtcha's boat comes to mind) I have a couple ??'s though.
There is some blue epoxy under the dash which holds on some wire harness holder that you can put a ziptie through. I'd rather use this stuff then try to get a drill and screw into some real tough areas. Where is the best place to buy the loom holders i'm talking about, and the blue epoxy. (Previous owners put the epoxy on and it looks like it works well) I want to button up some wire looms under the transom and getting in there with a drill will probably be impossible with the motor in the boat.
Second, here's my theory on how to make it clean and simple. I have an open motor so no bilge fan, no lights, etc. Just the basic stuff. It should be noted my battery is in front of the motor crank pulley, in between the two sponsons (right in the center on a Daytona 21).
Does this sound like i'm on the correct path? I don't want to over think the whole thing, but at the same time i'm not a fan of daisy chaining all of the wires together (except i'm OK with doing this on the guages) I have a mechanical oil pressure guage and fuel pressure guage so i don't have much wires to do under the dash.
- Run a 6 or 8 guage ground and hot up to under the dash where i will have three bus panels (one hot always, one hot with key on, and one ground bus) I will connect all under dash stuff to one of these three busses. (except for the starter solenoid wire which will make it's own run)
- On the transom i have three bilge pumps and a fuel pump. I plan on running the hots obviously to the dash but i was thinking of putting another ground bus in the back hidden on the transom up high out of bilge. Here, i will ground all the stuff that will be back there. That ground will hook to the block with a decent size wire.
- I want to get a junction block connecting all the dash wiring to transom wiring, so the motor can come out easily and any wiring changes don't have to splice into the original wire. (is that what those junction blocks are for?)
My last question is should i fuse the main hot wire coming in fron the battery to the dash, and what size fuse? Or should it be a push button reset? I wasn't really wanting to put a fuse box in (limited space) but of course i can do it if i have to.
Also, the MSD says one of the wires to be hot all the time. I have it hooked to the top mount starter which has worked fine. I don't like wiring on the starter, for a cleaner look where should i hook that up to? Sorry so long, thanks for any help. Below is only some of the bird's nest i took out.
Thanks for any help!
