Need Help with Trolling Panel Wiring

[quijibo]

I am trying to rewire the "Deluxe trolling panel" on my 1984 Lund Mr Pike.

I got a wiring diagram and I ran all new wiring(#6).

Battery #1 is in the rear of the boat and also provides 12v for cranking and electronics. Battery #2 is up front and right behind the panel. The trolling motor is an old Minnkota 795mx(24v).

When I hooked up the power it worked fine, until I switched it to 12/24 run. There was a big puff of smoke and now I need a new double throw switch.

Does anyone know what went wrong? I am an electric/electronic repair retard that really wants a trolling motor for at least part of my vacation.

Thanks,

Adam

do you have the red and black from battery 1 going to the same location on the switch? sorry i see the break now.

you can email the drawing to me, i have a buddy who is an electrical engineer and a wizz at 12/24 volt problems. if you can send the description of the problems too that would be great. thanks jeff, [YouNeedAuthorization]

Jeffrey, Your email address didn't come through and I couldn't get your pm to work.

Here is the address of the drawing;

Thanks, I would really love to be able to use this thing. It drives me nuts when something doesn't work.

Well, for one, see that red #10 wire jumping between the two poles/sides of the switch (in the red circle)? Cannot have that when you have battery (+) and battery (-) feeds (in green circle) connected to each pole. That red wire jumping from pole to pole of the switch creates a dead short across batt #1 when you put the switch to that position and that's what smoked the switch.

Probably could figure this out, but unfortunately I don't have time to pencil it out right now. Sorry...

Oh...question...the switch that burnt up...is one position supposed to be "charge" and the other position "run" or what are the two positions of the switch supposed to do?

[jeffreyd]

still waiting on reply from my buddy, i think he is gone until next week but have not forgotten

Here's what I think you need to do...

Remove the jumper going across the switch (scribbled out in green) and connect it corner-to-corner as shown in red.

Then, in the (presumably) "charge" position batt 1 and batt 2 should be in parallel for charging, then in the "run" position you should have 12V between black and red in the trolling plug and 24V between black and orange in the trolling plug.

The rest looks OK as best I can tell...

The "jumper" was actually built into the switch. I ended up just wiring up directly to the trolling motor plug and bypassing the switch. It just kind of bugs me that I have a 1984 boat that is in great shape and fully functional, except for this one thing.

Huh?

Built-in, eh? So this is a special switch you can only get from the boat mfg or something?
