Default Disconnect switch between trolling motor and battery?

Right now I just unhook my trolling motor cabels manually every time I'm done for the day. Is there some kind of switch I can install in there? What are y'all using? I went to the hardware store after a toggle switch but they all looked to light duty for a 24v trolling motor

You could use an automotive high current relay with a toggle switch to turn the current flow on/off.

You could mount a switch like this next to your plug-in.

I have a resettable breaker in line as a fuse protection. It is readily accessible on the sidewall of the battery compartment. This can also be manually tripped to break the circuit.
As such this serves double duty if one wishes to isolate the trolling motor from the power source. Similar to this https://www.amazon.com/Ocean-River-R...80795572&psc=1

A relay can cause you dead batteries if you forget to switch it off between fishing trips. Also make sure the relay you use is rated for continuous duty. A relay like a starter rely is not rated to be on for long and will either over heat or the coil will fail. Another side affect of a relay is if you run the batteries down you will get to the point the relay will open from low voltage and you get the "click click click" like the low battery in the car.



If you put a mechanical switch in make sure the back side with the exposed terminals are insulated as to not arc and start a fire if the compartment has other loose items in it. I just use the plug.

Use this plug system. It will not let you down.

Since the only time I remove my trolling motor is if it ever needs repair (which has been never), I replaced the plug and socket with a permanently wired in switch like this one: https://www.westmarine.com/buy/blue-...5?recordNum=48

This is for a simple 24v circuit. There are a variety of others for use if your system combines the batteries at the plug. Also look at the ones with removable "keys".

I figured if I do have to remove the TM, it is not a big deal to also disconnect it from the terminals of the switch to get it fully off.

Cobbled,
Don't you use a plug and socket to power your trolling motor?

If so, at the end of the day, unplug your trolling motor and your battery is isolated.

I really don't want to leave my trolling motor plugged in when I travel with the boat, or if the boat is off the water.


Battery Tender makes one of the best trolling motor plug and socket setups on the market:

https://www.amazon.com/Battery-Tende...ry+tender+plug

===================================
If you have a permanent hard wire trolling motor to battery connection setup in your rig, just use a high current battery disconnect switch:

For example:

https://www.amazon.com/Audew-Battery...AV3S36KCB5N9KV

Assuming that you have a 12 volt, a 24 volt, or a 36 volt trolling motor and battery setup, just interrupt either the + wire as it goes to the trolling motor or the - wire as it goes to the trolling motor and insert the battery disconnect switch.

With the switch open you will have 0 power to the motor. With the switch closed, you will have full power to the motor. Just mount the switch that is in a location that is convenient, but will not be hit or jostled during normal use of the boat and you will be good to go.

Good luck
