Im having problems with my Terrova 80 loosing power if I run it for over 3 minutes on #5 (or higher) dial setting. It will beep and reset itself in 1-5 minutes. My boat is a 2000 Triton TR-19 with factory wires and I'm running 50 amp fuses. Minn Kota recommends 60 amp but my 50 never trips. I'm thinking it has 8 gauge wire but do I measure the diameter of the copper only without the insulation to determine wire gauge?
Thanks,
Bart
If you look on the insulation the gauge should be imprinted on the cable, it may be faint but its there, it should be marked at least every 2 ft sometimes every foot. I hope this helps, also I would look at the specs on their website, triton that is, it should tell. Good luck with it and let us know what you find. Oh if by chance its 6 gauge you will know without a doubt, its as big as the cable on your car battery.
Thanks for the reply... I'll check it out tonight and report back
OK... I got 6 awg wire going to the TM and each cable checks 12V at the bow. I've directly wired the TM to these wires to eliminate the plug in and it still looses power... Any ideas or suggestions??
If the tm is new I'd contact a MinnKota service center and let them fix it.
Pull prop off and check for fishing string ...... This Might do it.

Between your 2 wires going to the motor, you should have 24volts. Perhaps you've got something crazy in the wiring like the batteries in parallel instead of in series.
Also did the boat use to have a 12/24 motor on it and if it did are you still using the original socket?Quote:

The Terrova 80 is a 24 volt motor so it has to have the batteries wired in series......also you say circuit breakers ( plural)......to wire properly you only need one circuit breaker.

I had a brain fart and typed 12V... I should of said 24V... It's wired in series with a jumper cable running from positive to negative.Quote:

I've added text to the picture but you have to look closely to read it.

I have 3 (6 awg) wires going to the front of the boat. 2 positive and 1 negative

This is how the wires are attached to the plug in. The plug in is a Marinco 35 amp 125V (3) post

I have directly hooked up just 1 positive wire and the negative wire to the TM wires (to eliminate the plug in) and it still looses power on anything of the #5 speed setting. It will beep and come back to life after 1-5 minutes. I pulled the prop and everything looks fine (no debris)...
one of the batteries may be bad i woul suggest having them tested
These are brand new batteries. I had the same problem with the old ones
You should only have 2 wires hooked up to the plug up front if running a straight 24 volt, that is the way mine is done. We went from a 12/24 setup also. Hope this fixez your problem
You should only have two wires going to trolling motor.
1 (+) and 1 (-).
And only 1 circuit breaker.

By your drawing and labeling in the first pic. It appears that fuse 2 is the 24v side. If you are ABSOLUTELY sure you have the motor connected to the 24 volt side you can do the following.
1. Run the motor until it quits then put your hands on every connector including the jumper connector between batteries. If you have any of them warm, you have a potential problem.
2. Flip flop the 2 wires on the plus side of the batteries then move the plug wires to match. This will cause the 24volt side to become the 12 volt side and the 12v side to become 24v. This should eliminate the wiring as the cause.
After this you only have the batteries and the motor left as the problem. At the head of the motor, there are 2 connectors on the larger wires that go down to the motor. Pull the 4 screws out of the head and check the connectors that push together and make sure they are clean, bright, and pushed together firmly. I would probably do this before I jacked around changing the wiring. This would also be a good place to check for 24volts to make sure that all is connected properly.
Hope you find the trouble soon.

As an after thought, the easiest way to know if you have everyting connected properly is to pull off the battery cable that you have labled as fuse 1 in the picture. If the motor runs, it is wired correctly (but still may have some other problem like a loose connection). If the motor does not run, it is incorrectly wired to the 12 volt side.
Rcc, the motor will run on 12v just not correctly.Quote:

Is that a self resetting circuit breaker? How many do you have?
From what I can tell he has two. And he has two (+) wires going to motor. One 12v and one 24v.Quote:

I found my MK Terrova wiring diagram. It shows two batteries connected in series and TWO wires going to motor.

You should be reading at least 25.3V on the wiring when the batteries are fully charged.
OK... when I previously hooked 1 positive wire directly to the TM cable (eliminating the plug in), I'm not sure which positive wire I hooked up. So tonight I'll verify the 24V positive wire in the bow and directly hook it up (and the negative) to the TM wires. Thanks for all yor help and suggestions. To be continued.....
I have a feeling you were on the 12v side and the trolling motor wasn't happy about it, I hope we have helped you solve this problem and let us know how it works out.
I hooked it up to 1 positive wire with 24V and it ran on #8 setting for 8 minutes in a 55 gallon drum until the 50 amp breaker tripped. I think we have solved my original problem but now I'm going to need a 60 amp breaker.. Any sponsors sell them??
Thanks for all your help and suggestions!
Bill at big river marine sells them. He goes by BRM on here. That's who got me mine. And for a good price. Tell him Gator sent ya.

Glad you got the problem worked out.
I've been away from the forum for a few days and wanted to clarify the below trouble shooting technique since someone may run into this again. The below is a way to trouble shoot the problem with minimal test gear.
The above was followed with the below post which made me realize I may not have been clear in my directions.Quote:

When I looked at the pics, I noticed that fuse 1 was the 12 volt side. By pulling the cable marked as fuse 1, this would kill all 12V power to the front and leave only 24volts. If the motor was wired incorrectly to the 12volt side, when the wiring to fuse 1 was pulled the motor would then not run at all and you would know the motor was wired to the 12 volt side.Quote:

I would try it on the water before I replaced breaker. Running in a drum you are aerating the water and losing a lot of cooling around the motor which could cause it to heat up and trip breaker.
