another troll motor question.

[skeeter]

ok i got everything hooked up, batteries are charged, but TM just doesn't seem like its turnin as fast as it should. (yes, batteries are charged) its a 24v minn kota 74# riptide.

TM has 2 black and 2 red wires. I have 2, 12 v batteries wired in series to give me straight 24 volts. no 12/ 24 switch. i spliced both blacks to the black from the battery. do i splice both reds from TM to the red coming from the battery or do i gotta figure out which red to use?

[Samson]

Both reds on one battery, both blacks on the other.

[skeeter]

thanks.

thats what i did. both reds to red, both blacks to black. just doesn't seem to be turning as fast as i think it should. guess i need to water test it!

[BowSlayer]

I'm pretty sure you need to figure out which red to use.

USCG Electronics Tech here.....which ever battery you have both black wires going to....put the red wires to the positive on the other battery. Not trying to be captin obvious just a past observation from my job. Also it could be that one of the black and one of the red is to hook up to an external battery gague? Are all four wires the same size? If you look up the exact model on Minn Koda's website they have some diagrams. It also mentioned you MUST have circuit breaker installed for this motor. Just trying to help

[skeeter]

all 4 wires are the same size.

Try using one black and one red with a jumper and see if it spins faster. Use the Dia for 24v but only use one black and one red.

That is real strange that the TM has 2 sets of wires. I've never seen that. I had the Great white version of that motor on my first bow fishing rig and it only had 2 wires as does my 80# 24 volt motor. If the motor can be 12 or 24 volt, yet doesn't have a switch, maybe it has to be wired 12 or 24V... If that's the case, you've fried the 12 volt side by doing what you did because you've put 24 volt across both sets of wires...

I agree also.

The early 74's had 2 black and 2 red wires but each color connects side by side to the board. The only thing the 4 wire system did was lighten the load on the wire and connectors. Minnkota did away with the 4 wire system shortly after it came out. Both reds to the positive terminal on battery A, both blacks to the negative terminal of battery B and a 10 gauge or bigger jumper from the negative on battery A to the positive on battery B. 6 gauge marine duplex from the batteries to the troller plug is a good idea also. It's hard to tell if a troller is working right without dropping the boat in the water and seeing how hard it pulls. If it doesn't pull like it should under load more than likely the cause will be:
1. Low voltage at the troller caused by weak batteries or under sized wire from batteries to troller.
2. Water in motor.
3. Brushes or armature issues.

ALL trolling motor wiring systems should have a fuse or breaker wired in near the battery in case of a short circuit.

Another very good write up.

Take the prop off and make sure there's no line wadded up.

Good idea.

went to the lake today. all is good! thanks for the suggestions.
