Re: need help please
You apparently have a 12/24 setup. There are several ways those systems were wired so you need to provide very exact information for us to help you. However, based on the limited information you've given so far, it is safe to say the "short boxes" you mention are indeed circuit breakers. 1) Since there are two of them, that means one of those boxes connects to the positive terminal on one battery and the other connects to the positive terminal on the other battery. 2) Now then, check to see if the black wire is paired with either of the red wires or if it seems to run forward all by itself. 3) Also check very carefully in the battery area for another black wire just like the one you currently identified. 4) How long is the second red wire that you mention that's connected to one of the other red wires? 5) Does the trolling motor plug have two terminal, three terminal, or four terminals. 6) How many wires are there going from the trolling motor plug to the motor itself (the answer will be two or three). 7) Check the battery area to see if there is a short "short jumper wire" the about the same size as the red wires laying loose. Until you answer those questions that's about as far as I will go. Something is missing from your description since what you describe does not work for any 12/24 system.
