To get 36 volts, number batteries 1 thru 3. connect pos 2 to neg 1, connect pos 3 to neg 2, connect pos 1 to trolling motor controller and neg 3 to ground on trolling motor.
This is only a solution for 3 battery system.
For 4 battery system, connect 4 to 3 pos to pos and neg to neg.

I am getting a charge between my aluminum boat and the trolling motor system. I get a white buildup on the motor shaft and the outdrive anodes. It may also be burning up other electronics as my GPS antenna and 2 radio's have recently died.
Can I ground the batteries to the hull?

### Show proper battery hookup for 24 volt trolling motor, 2' 12 volt batteries

to get b24 volts from 2 x 12 volt batteries
connect the negative (- ) terminal of one battery to the ground point on the motor
next connect the positive terminal (+ ) of that same battery to the negative terminal of the next battery
connect the positive terminal of the last battery to the power terminal of the motor
so it will be negative to ground , positive to negative , positive to motor or motor control
(-) to ground (+ ) to (-) , (+) to motor
That is called a series connection and increases the voltage available

The heat is developed from to much resistance from batteries to TM, check for loose/corroded connections at batteries, including the jumperwire, also check the size of wire from battery to plug, should be at least 8 gauge if not 6 gauge depending on the length of run. If corrosion has built up inside the wires this will also cause high resistance causing excessive heat build up. I would prolly just replace boat wiring to make sure none of the above problems are present. Use tinned copper marine grade wire that is multi stranded.

You have a high resistance short either inside the wiring or the lower unit. This will cause a voltage drop. I would be very careful not to keep it connected too long cuz the battery is trying to keep up with the current demand and may explode.

Is this a straight 24V system... not a 12v - 24v.Correct..
The best advice is use a 50-60 amp resettable breaker..with 6 gauge wire (minimum 8 gauge) ... make sure your connections are clean, tight, and greased to prevent corrosion. USE a BIG HEAVY "jumper" cable between the + and - terminals.

Here are several sites that explain what you need to know..
I went from a 12-24v to a straight 36v Motorguide on my 21ft triton.. WOW!!!! talk about BAD A\$\$!!
I use the felt washers under all battery connections and the battery spray liberally on each connection..

### 24 volt trolling motor wiring

Just like a flashlight. Positive to neg, In a loop going to the motor. That is the jump between the batteries, One red wire coming in from motor, it will go to pos, from one battery, the neg will go to the 2nd battery pos. From the 2nd battery neg will go to the motor. That is it, one jumper connecting the 2 batteries, will create the 24 volts. Hope this helps.

### Wanting to install motorguide 24v trolling motor in boat, will it work on just 12 v system

No. you can put in extra batteries and use it, but you must remove you charging system from them to use it that way. Not really practical.

### Converting From 12/24 to Starght 24 Volt

if it is 24v. then you need to connect 2 battery in parallel. since the battery is only 12v.
if one battery is shoing red and the other is sohwing green, that means you are using 12v only, not the 24v.
connetion as follow:
positve of battery 1 to the motor, the negative of battery 1 to postive of battery 2. the negative of battery 2 to the motor.
