Location: Hastings, mn, 55033 | I have a Lund that is set up with a 12/24 volt system instead of a straight 24 volt system. I cant get a trolling motor to work at all, but they worked last fall. When using a multi meter to check I have the proper voltage at each step, up to the motor.
I am assuming with this 12/24 volt deal the internal jumper is inside the male plug(that gets wired to the trolling motor) as its only after plugging that in that I get 24+ volts on the meter. Is it possible that something with that jumper is allowing the right volts through when the motor is not connected and I'm just testing bare wires, but somehow failing after the motor is attached and there is an amp draw?
For those unfamiliar with this setup, the female receptacle on the boat has 4 wires going into it, a positive and negative from each battery, and then 4 prongs. The male plug that gets wired to the trolling motor has 3 wires, a red, an orange and a black, and 4 holes that mate up with the 4 prongs in the female receptacle. There is an internal jumper of some sort that allows you to either run a 12 volt motor, a 12/24 volt motor or a 24 volot motor off the same system depending on how you wire the plug to the trolling motor.
When I plug the male end into the female on the boat, I get a reading of 25.6 volts when hitting the orange wire with the positive lead on my multi meter and the black with the negative lead. I got the same volt reading after I cut the plug off on the trolling motor side of the connections, so before cutting it off those wires were going directly into the trolling motor. If it has proper volts at that point I am at a loss as to why it wont power on.
Motor will work when wired direct to a straight 24 volt setup, so it has to be something in the plug system, but I dont know which part when it all seems to have the proper volts going through it. |
