Sorry to keep making all these new threads but I greatly appreciate all the help I have received.
Im remodeling my 86 bayliner and trying to make sure all the mechanics are working before I start replacing the floor and deck.
so I have a motorguide brute 750 45 thrust with a foot pedalamd 12v or 24v toggle switch on the side ot it... it has 3 wires that come out and run to a plug. They are (red, white, & black) I think since they are faded lol. It is a 50v plug with an odd shaped prong. Then from the back of the plug it has (black, green, and yellow wires) that run to the battery. The black wire has a circuit breaker.. I used it several times with only 1 battery. But I removed it years ago and forgot how it hooks back up lol...
any ideas? any ideas what the red, white and black wires are? I assume 1 is 12v pos. 1 is 24v pos. And 1 is neg??? Anyone know which one is which?
thanks
