24 volt problem

hey guys i must be hooking somthing up wrong but i can’t figure it out i’m only getting 13v both batteries are new the motor runs at 1/2 speed help- if you can

gutpile,
see if your motor is a 12/24V model, if so, you may have the volt switch in the 12 position, where it would need to be in the 24V position to get 24V out of it. hope it is that simple, I’ll keep my crainial going. good luck. Jack…

in the battery compartment, are there two complete sets of wires?? one for each battery, that leads up to the plug. or one set of wires to the compartment, that you would then connect the two in series or parallel??? Jack..

jack i’ve got one red and one black comming from the motor then one wire that connects the two batteries that goes + to + i’m lost i know it’s somthing simple but i’m not seeing it and i lost my wireing chart

Was it working before, or is it new?
The plug needs to be wired as 24 VDC also.

It worked fine before

I don’t know if this is the answer but positive has to go to negative if you have two batteries. If you put positive to positve you still get 12 volts with more amperage. If you have two batteries the wire that connects the two batteries together has to go from the positive post on one battery to the negative post on the other battery, this way your adding 12 plus 12 instead of just using 12 volts with alot of amperage, hope this solves it.

Id check connection and quality of connection, I cant see any reason if it was working fine before, maybe just a small chunk of corrosion interfering on the connector or a possible crack in the wire itself??

hi Brian,
Am glad what we talked about worked out for you and you got it going. Now go out there and GO fishing.
Jack…

Hope you got it figured out. Just this week I rigged up my new boat with a 24v 65lb Maxxum. I have a pretty good Idea of how electricty works so I knew that I had to hook up the two batteries in series. I decided to get lazy and use the jumper in the marinco plug instead of shorting the wires and jumping the neg of batt 2 to the positive of batt 1. I mounted the trolling motor at about 7:30 PM(1 hr) and wired the plug in (.5 hr) and plugged it in. Turned on the momentary switch and nothing! What the **ll. I fiddeld with it till 11:00 PM and nothing. Decided I would start fresh the next morning.
9:00 AM the next morning start over. Nothing. I rewired the plug in eliminating the jumper in the plug in and shortened up all the wire leads and put in a short jumper wire between the two batteries, still nothing! What is going on here. At noon I decide it must be the Auto Reset 50 amp circuit breaker. The Minnkota manual says to use a 50 amp manual reset breaker. Decide to drive to marshfield to Krafts to buy a 50 amp Manual breaker. They don’t have any and the parts guy isn’t sure what they use on the boats they rig (really said that) but he thinks he can order me one. No thanks I can order it cheaper from bass pro. I went to the local Napa dealer, they don’t carry them. So I decide I will just go to fleet farm, buy a multimeter and check out what my voltages are.

I get home about 1:30 PM. I decide for the sake of my sanity I will take off the circuit breaker and just test out the motor with out one to make sure it’s not the new motor. I test the circuit, 25 volts were good to go there. Plug it in and push the momentary switch, you guessed it – NOTHING. Now I’m just a little PISSED. The brand new motor doesn’t work. Angrily I start towards the plug in and I must have accidently bumped the speed dial. It went up passed the 10 percent speed and the prop starts spinning away. I HAD BEEN CHECKING THE MOTOR EACH TIME UNDER 10 PERCENT AND THE MOTOR WON’T START UNTIL IT GETS TO THE 10 PERCENT LEVEL. 6 HOURS I FIDDLE F—– WITH THE WIRING AND I ACTUALLY HAD IT DONE AFTER THE FIRST TWO.
Sorry to get long winded and hijack your post, but I know your frustration. Hopefully yours is something as simple as mine was

Hey guys thanks I got it

STG113,
that’s the way to stick with, and the happy ending is, you found out the prob before you pulled out the wires and motor. I had Brian call me this morning, and we got his motor working right, so all is well with his boat also.
like I told him, now that it is all working good, Go out and GO fishing. good luck. Jack..
