Running to slow indicates voltage too low
you will have 3 X 12 volt batteries connected in series ( positive to negative to positive to negative with positive to motor The first battery negative connected to the ground on the motor
the multicore wire cable is for 12 volt draws as in fish finder, light etc and can be connected across any single battery terminals
They could also be for a foot controlled pedal that is forward and reverse operation
that will be explained in the user manual

SOURCE: re sent wire diagram gat all messed up

Hi
have we spoke before in previous post?
the red can go to any 12v live peramanent such as wire to clock or other item that has power with ignition off and the same with the yellow if your putting these to the same permanent live say from clock you can join these to together red/yellow to red on clock
the black can go to any metal or neg wire.
This should then have your device working the only problem im looking at for you now is the pink wire as this stops you using the device whilst driving as it goes to handbrake but i need to find out if its live or negative.
You could just wire the red/yellow to live and black to earth then see if it switches on and works if not then let me know and ill see about the pink wire ok
Makes sure you use inline fuses on the live wires so as not to short the device out.
Make sure you know what is permanent live to put the yellow/red wire to.
It doesnt need to be ignition it only says this so you cant use it with ignition off but you can wire it into any live feed from clock or switches so its up to you what to wire it to its just the pink wire im concerned about.

PINK: does it tell you to put it to live or earth on handbrake switch?

let me know ok

Great white wont turn motor runs but wont turn


Do you mean you can hear the motor turn but the propellor doesn't turn?
Then check the break-pin of the propellor. It's a security device that will break when the propellor hits an object in the water...

Motorguide trolling motor


The first thing to check,(After making SURE the electricity is disconnected to the trolling-motor) remove the propeller and see if the shear-pin (Usually made of brass) in in place and not sheared/broken.
If it is, your local marine shop should be able to provide a new one. I always carry spares. If the pin is OK, the windings may have an electrical fault that would require a factory-repair.

Hey Chris,, you are starting a project (or wanting to) that is going to be problematic... It will be easier to go buy a new trolling motor with the money you are going to spend attempting this conversion... the newer trolling motors are so much more efficient...

I have a 74LBS thrust trolling motor that hasn't never in my opion worked right, I don't think its wired right to get the proper 24 volts, However I have took it loose and hooked it directly to 2 marine...


Here is a picture of the wire connection for 24 volt. Compare to yours is it correct? If it is, I wish you listed make and model I could of sent you the right picture diagram of you motor. Use this picture as a starting point. Test the wires through the motor testing for 24 volts. Again if I knew make and model I could show you exactly were. Last if voltage is correct all the way through. The motor is the last thing to tear down. If the brushes or armeture is damaged in anyway, or manufactured wrong, it would lead to power loss.

I have a great white 67 lb thrust trolling motor . I can run it at 1/2 to 3/4 power and it will run for a while but when you go to full power it will shut off and you have wait a while before it kicks back...


Sounds like it's heating up. Check your wire size. For 24 volt: 6 guage wire is reccommended - that's pretty heavy. Also check the wiring of your batteries. It's easy to get mixed up if you have 24 or 36 volt system. One more thing...check the fuse size to make sure that is correct. Hope this helps. Brian
