More wiring questions
In the attached photo you'll see the cord coming from my minn kota charging system (3 wires; white, green, and black) and I need to wire those to the two wires (the ones with the fuses) that will connect to 1 battery. How do I do it? It was connected before, but I had to cut it, but when I was taking it apart I pulled to hard and pulled it all apart before I could see how it was put together
Second question, when wiring my two batteries in series to run my trolling motor, do they need to be exact same batteries? Because right now they are both Die Hards but they are different sizes and amps. One is a few years old, and the other is brand new...both are deep cycle. I heard that running one old one and one new one will draw the new battery's life down quicker than normal. Is this true?
Also, when using this minn kota charging system (4 bank), will I run one cord to both batteries (treating them as one big 24v battery), or will I run two seperate cords, treating each battery seperately (12 v)?
