The boss gave me an old OMC trolling motor...

[WTL]

Its actually superior to my current one, and I'm trying to figure a couple new things out.


Instead of just a red and black wire (neg and positive), it has a red wire, a black one and a white one. Its a 12/24 volt motor, which I've never dealt with before. What wire is what?



Thanks in advance for any help.

The last one of those I had was tricky but not that hard

red - pos
white- neg
black- neg

with that in mind you will need to run 3 wires to where you attach your trolling motor . and you will have to hook up you batteries in series imagino your batteries sitting side by side you will need a jumper wire from neg on one battery to pos on the other

now connect the red to the battery positve post
connect white to the neg post same battery ( this gives you 12 v )
connect the black wire to the neg post on the second battery ( this will give you 24 volts )

hope this helps

What exactly is the advantage of going 24v as opposed to 12?

[ahassell]

when you select 24V you will get more power I had a 12 / 24/36 talk about a pain to wire when the wind was howling i could bump it up to 24 v to hold on a point and sometimes had to use 36 when condtions are really rough

I have a new Motor guide 70lbs thurst 24 v I love it fish all day and still have power you have more power supply with 2 batteries rather than 1

word of caution dont use your starting battery as your second battery you could drain the battery and not be able to start your big motor use two independant batteries

Adding another big deep cycle would be a lot of weight for my boat. Would it make sense to get a smaller, cheaper batter for the 24v operation and use it sparingly?
