    Last summer the dog got all excited when we were fishing and broke the toggle switch that I had my structure scan connected to. Got a switch hooked the wires up and nothing works. I checked for power and there is power coming out of the cord but, the modular isnt powering up. No lights of any kind come on. So frustrated and worried the modular crapped out. It was working fine up until the toggle switch got broke. Any suggestion or am out of luck?

    Dam dogs, I usually have one in the boat also.
    Mail it in or take the boat to someone who can fix it.
    I wouldn’t think you will get warranty service on the unit.
    Action electronics in Anoka would be my recommendation for service.

    I sent action electronics a message on facebook so will see if I hear back. It doesnt make any sense though how it was working fine until the switch broke. I figured I had wired something wrong but, there seems to be power going through the cord. Going to get a different switch or try wire it directly to the battery just to see if it will power up.

    Have you checked fuses to see if one is blown?

    Yes the fuses are fine.

    I think there are 3 wires to power that unit. 1 pos I neg and one (not sure the color) is a trigger to turn it on.

    After typing that it doesn’t make a ton of sense but that’s what I remember. What colors are all the wires?

    Yes your correct there are 3 wires red yellow and black. The way I understand it is that the red is the positive or hot wire,black is the ground and yellow is for the accessories or axillary switch?

    A few questions. I haven’t looked at the wiring in a while though.

    Are you sure the dog had anything to do with it? Maybe it just busted on its own.
    Broke = repairable
    Busted = non-repairable. )

    Why is there a switch in the circuit? And where is the switch in the circuit (positive or yellow)?

    Btw, black is negative, not ground on a boat. There should not be a grounding plane like in a car, unless you have marine radio antenna, and then it is also isolated.

    Have you tested for power on the leads enter the unit, after any connection, switches, or fuses? Then compared that power reading to before any connections, switches, or fuses?

    I put a toggle switch in on the instrument panel so that Im able to shut the unit down when im done fishing otherwise it would be on all the time. My boat is a tiller so What happen was when i was fishing the dog gots all excited anytime a fish is caught so she was jumping around when i was reeling a fish in and in the process she hit the toggle switch and broke it off which also shut the structure scan off. I got a new switch and put it in but, couldnt get it to work. This all happened all late last summer so before I put the boat away for storage so I never played around with it. So this weekend I was monkeying around with it and noticed the unit isnt powering up at all. I checked for power everywhere including coming out at the connection and all seemed good. I bought a new switch yesterday so Im going to put that in today and hope and pray thats the problem. Worried that something happen to the lss-1 and may have to replace it. I hope thats not the case

    My understanding is that is what the yellow wire does. It shuts down the LSS when the depth finder is turned off/disconnected. A switch would be an extra precaution shouldn’t be necessary.

    I guess I don’t understand how a faulty switch could fry an LSS unless it was either shorted or reversed polarity.

    I just installed the new switch and now it all works thank God. So relieved the LSS-1 wasnt fried. So frustrating sometimes trying to figure out this electronic stuff. Now I have to get my dash board put back together. Thanks every one for the responses and help.
