battery/trolling motor question

14 posts in this topic

I was using my trolling motor this past weekend and on the last day of the trip, encountered a potentially serious issue. When I turned my old trolling motor on, my battery (1.5 years old), started smoking and hissing from the positive terminal. The higher I turned the power on the motor, the worse the hissing and smoking got.

At first I thought it was the battery, but now I'm wondering if maybe a wire or connection shorted out inside the motor.

Any thoughts??? confused.gif

Loose terminal connection. Assuming you don't have a fuse or circuit breaker on the hot supplying the motor, if the connection was good, and there is a short in the motor, you wouldn't likely hear anything but would experience a wire burning somewhere between the battery and the motor. The hissing was probably the arc jumping the gap in the poor connection. This is a dangerous situation that could cause the battery to explode. I'd find the cause and repair it ASAP!

Could it just be from a rusty clamp on the trolling motor wire?

Yup. Take all the connections off the battery and clean up the batt terminals and the wire connections.

Go to autozone or napa and pick up a new pair of 50 amp clamps and install them and give it a try. Hopefully that is your problem. When trolling motors start going out they can have an excessively heavy current load which would definately contribute to sparks flying on a poor connection.

If the hissing happens with new clamps and clean battery terminals.. take the motor in for repair or replace it.

Thanks for the help guys! Hopefully it's not time for a new motor yet...

I replaced the clamps and that seems to have solved it. Thanks again for the advice.

Now if anybody wants to tell me why the heat in my Jeep didn't work today... frown.gif

Check the coolant level....

Coolant??? You must mean the water level in the battery. Coolant is usually found in a radiator smirk.gif

"Check the coolant..." was in response to his question about why the heat wasn't/isn't working in his Jeep.

But, I do agree, he should check the water level in the batteries too.

No worries, Mate.

It's good to keep an eye on things so bad info is not disseminated.

Thermostat?

I checked the antifreeze right away and that's full. The temperature is good, so I know it's not the thermostat. Must be something with the heater or some kind of a valve. I also had a problem one day this summer where the AC would blow VERY hot air.

      Shagawa in Ely has a public beach.  That's the closest to Bear Head that I know of.  You'd have to launch a ways across the lake but you could just motor over to it.

      Sorry for late response.  The Gander in Eden Prairie had quite a few...

      Catfishing is pretty stable right now. The water is getting very low making the north end of Grand Forks begin to get sketchy for travel.  The lack of current has the fish spread out also.  Stay on the move and when you land of fish you should have no trouble catching them.  The best areas have been anywhere you can find more current than the surrounding area.  The middle of the River in mid range holes has also been a good place to look. 
        Bait has changed for me this week with frogs being the hands down number one so far.  Sucker and goldeye have been working too.  I still believe getting bait in front of the fish is is the key more than what the bait is but try it all.   Remember the I-29 Catfish Classic is in just 2 weeks.

      Made it out last night. Beautiful night. Caught a bunch of Crappies, sunnies, a norsky and a few walleyes. All CR. Amazing how quiet the lake was. I was the only boat out for the most part. First boat in parking lot at 5:30 and no AI inspector this time. Have not seen them for quite awhile now.... Water temp was 78. Panfish were caught on simple Jig/plastic in about 12 feet along shoreline weeds. Walleyes on spinner/crawlers in 17-20 on midlake structure.

      Berserker Bass.   This is probably the most exciting hit I have ever had from a bass.   Had to slow it down to get the full effect .Berzerker bass video

      Have not fished down there but up river a little way in the Ramsey area I have been doing well on smallies Either trolling raps up river bouncing of the bottom or drifting down pounding the shorelines with meps spinners.   Meps are one of my favorite lures for the river that and buzz baits.   The Mississippi is fun because you have a chance at catching anything.

      Im wanting to go and fish the missisippi river by my place, there is a little inlet with some down trees, a drop off  and a little bridge that goes over the inlet. Its off of east river road at the end of 79th.  I believe its called riverview heights park. My questions is, has anyone gone fishing there? I see people there quite often and have chatted with them a little bit, but haven't gotten much out of them. It looks promising for some largemouth and catfish. if you have fished there what works good? and are they biting now? I will be there at about 5 am tomorrow morning.
