Guys I gave googled my tail off and cannot find a logical answer, so I am presenting this to the forum.
The PO of boat did some interesting things to the wiring
. My present problem is that the blower can only be controlled by the breaker below decks. I assumed that the solution was just running a wire to and from the switch on the engine
panel at the helm
. When I got into the project
I found that the panel switch was already wired to the ignition. So I now have two hot leads.
Lead #1 from panel to blower controlled by the blower breaker.
Lead #2 from the hot leg on the ignition switch, through in-line fuse to switch on panel, from switch to the blower. This line was snipped and left next to the blower.
Everything I found on the Internet
called for a standard 3-way switch, but there is no sign of that was ever done here. The Tartan wiring
diagram does not show this connection. My DC wiring skills are rusty, but everything I know about AC screams that tying these two hot lead together and feeding the blower with them is a bad thing....
So the $25,000 question is.... How should the blower be wired such that it can be controlled from either the helm/engine panel or the breaker panel.
