Thread: Terrova 80 problems

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.

Is that a self resetting circuit breaker? How many do you have?
