Default Motor won't start with depth finder plugged in

I have a Lowrance Elite 7 TI at the front of the boat and console. I just had these installed when I had carpet done and I had taken the boat out twice when I purchased it and it ran like a dream, it's a 1996 Javelin 389TDC with a 175 Evinrude Intruder. I took it out on the lake and it would not start tried many things but nothing worked so we took it to a boat mechanic (not the one that did the work.) I had the boat mechanic diagnose that I needed a power pack so I bought one and installed it myself and the boat cranked right up at the house. Well I got out on the water and it did the same thing wouldn't crank so I thought I flooded it, tried it periodically for the next 2 hrs. Well I was sitting at the steering wheel just watching the depth finder wondering if I had just got into a money pit. So I turn the key and the depth finder turns off I try to turn it back on and it won't. I turn the key off and it turns right on when I power it up. I unplug the depth finder and instantly as I turn the key the boat cranked. What is my problem here? Note that it cranked with the front depth finder on at that time, but then after waiting a few mins it did not so I unplugged both and it worked perfect. So just to test while the boat was running I went to plug in the power chord and no sooner than the pins touching, I didn't even have it started in yet, the motor shut off.

Sounds to me like an ignition wire is grounding out due to Installing the 2 depthfinders. Installation means pulling wires for the transducers and power cables.There's a good chance insulation got rubbed off, cut etc, and a wire could be shorting out. First thing I'd do is check the power cable for each depth finder and make sure neither has been pinched, cut etc. Best to go back to the installer and show him the motor runs with the D/F's disconnected, but not when connected. S**t like this can happen pulling wires.

Well I called him (he is 1 1/2 hrs away so I'd like to try myself) and he said that he connected them to the existing wires for the old depth finders. In the console it had a Lowrance that was very old and looked like a Vexilar type deal. And the front had just a Lowrance temperature gauge that he hooked to.

Okay, get yourself a couple long leads to connect the D/F's right to the battery, bypassing all the boats wiring. Just be sure to use a fuse to protect the D/F. If your motor starts and runs while connected that way, you are fixed and done. Many electronic manufacturers recommend going straight to the battery with a fuse. I have a separate set of fused #10 wires feeding a terminal board. The terminal boards powers my 2 D/F's and my NMEA 2000 backbone.

Ok so I go under the console and it looks like the wires aren't reachable, but I will try to pull on the wires at the console and see if I can see them in the back. I will update you when I get the chance because it's snowing currently where I am.

Hey man while I have someone knowledgeable about boats would you happen to know how to fill and operate the livewell on a 96 Javelin 389TDC?

Can't help with that. Did wiring to the battery fix your starting problem?

I haven't gotten out to look, it's been snowing where I am but I went under the console and the wires go toward the back and when I go to the back I don't see which ones are the depth finders, will have to wait till it's not 15 degrees haha

Replace your batteries. How old are they.

We found the problem, it took a couple hours but an electrician from my work came and helped me. We checked many things and finally found that the guy who wired em up used the wrong negative wire (we don't know what it goes to) and with the depth finders plugged in when the key turns it made everything lose it's negative. We ran a wire straight to the negative terminal and everything works fine now.
