24 Volt trolling motor wiring question

Default 24 Volt trolling motor wiring question

Im not sure if I post here or the electronics forumn.... mods, please move if needed..

Anyways, on to the question.

I have a minn kota riptide 80lb thrust (24V). The dealer wired a plug on the end of the cord to be able to plug into the boat recepticle. I have had 2 recepticles go bad so far (in less than 4 months, maybe 4hours on the motor) and almost ruin the fishing trips.

My question is can I hard wire the trolling motor to the wiring behind the plug and just be done with the plug, or do I have to have the plug? If I can hard wire it, how do I do it since its 24v? There are 2 red and 2 black wires coming from the battery, can I just use spade connectors for everything? I would use the correct marine ones. I don't want to void a warrenty or anythinget so any help would be appriciated.

Btw: tried searching, but the search function is quite lacking....

Yes you can hard wire it. Issues are then hard to remove for maintenance or if you want to store or use the boat without the TM. Be sure you do have some way to shut off the power quickly in case something goes wrong. On one of my earlier I Pilots the motor started turning and I could not stop it unless I was able to pull the plug.

I don't understand why you are having so much trouble with the plug. I have had plugs for years and the only issue is corrosion or the contacts getting too loose.

Someone else will have to tell you about a spade connector, I don't know what that means.

My MinnKota 24-v iPilot died this week. I am troubleshooting it, and the plug is a suspect. In my prior boat, I hard-wired the TM because the receptical corroded. It does make removal more difficult, but works. Use a circuit breaker, and run proper gauge wire.

I thought I understood DC current but maybe not. I don't understand why you have 2 reds and 2 blacks, unless the wire is not of sufficient size to deliver the required amps at full speed. Maybe replace the wire with the correct size?

I used the MinnKota connectors for my motor. They work very well with a positive connection. Also put a connector on my charger to plug the battery in.

The reason for 2 sets of wires is so that I can get 24v to the trolling motor. 12v from each motor, wired in series.
Thanks guys for your help. I ended up taking the boat to the marina, and having them hardwire the trolling motor.

Get the Marinco twist-lock plug. Make sure that you get the 6 gauge adapter for the receptacle portion.

Just a thought I have a breaker on my hot wire going to trolling motor under console. Just to kill power just like a breaker in your home. It it also hard wired directly no plug.

My recommendation if you don't remove the motor every trip is to install a simple on/off battery switch. If you do remove every trip then it is best to find a serious plug that can take the plug and unplug often as Marlin recommended. Just remember that you should not charge the batteries with the trolling motor plugged in. I got that directly from Minn Kota. Disconnect power if motor is not in use, charging or in storage. That is the number 1 cause of failure.

Be safe !!

A poor connection will generate heat and kill the plug. Check wiring connections in the male and female plug parts.

Replace both the connector and the receptacle and coat the wire ends and the plugs with dielectric grease and install a battery cut-off switch near the batteries.

If you have 4 wires you have an older boat that was wired for a 12/24V TM. It's very simple to rewire to make it 24V only since no one makes a 12/24V TM anymore.

The marina hardwired it, but also installed a heavy duty breaker on it, so I can trip the breaker to charge the batteries.
Took it out twice so far, with great success.

1 red and 1 black from each battery(total of 2 reds and 2 blacks from the batteries to the trolling motor) to the trolling motor wiring. Then only 1 red and 1 black into the trolling motor.

Sorry to dig up the past lol

But how is your 2 tm wires connected to your 4 wires from batteries?

Diagram and materials used please

I just bought a 80 lb Minn Kota and busy getting all the stuff I need. Minn Kota website specifies 8 gauge wire from motor to batteries. When I went to buy wire the price tag amperage shows 50 amps and I think the motor draws 56 amps. Not sure what to use - any advice? Will use about 12 feet in my 175 Scout Sportfish.

What gauge for the short connection wire between the two batteries? 1?

Ive read somewhere to use 6ga on the tm and it will be sufficient for any tm on the market. I have 8 with a 60amp breaker that mounts to the battery terminal.
I also read that you don't want to oversize the fuse/breaker because it works against you not being able to do what it's designed to do.
For your jumper btwn the batteries just use a jumper that the same Ga as your car battery. Whatever that is. 4ga maybe.
You can get those at Walmart or auto stores but they probably aren't marine grade. Or a expensive. And you know you're not getting the right stuff if you're not paying top dollar.

Message hulltruth member charger guy for awesome deals on 3 bankb chargers.

Don't fry your batteries on junk chargers. That is something worth buying the best.
So im told

Get six gauge wire for our connection between batteries. Won't hurt a thing. Many battery stores have them premade with compression affixed terminals ready for use. Just purchase the length you want.

If you are worried about excess current draw ruining your trolling motor put on a 60 amp blade fuse on the hot end (red) just before the ring terminal to the motor.

The motor may draw 56 amps at maximum use, but most of your motor use will be well under 50 amps and you are very unlikely to burn up you wires with motor use. You will melt your wires and burn up your boat when you cause a short between the terminals. (Metal pole connects the tow, fishing rod, or any source for a short)

Thanks Fishua,
If you have any charger questions, feel free to ask.
