It should not make any difference. What ever you hook up to that battery will just run it down sooner. Not knowing what you are trying to hook up to it makes it hard to give a good opinion.
Hooked to positive and negative of one battery going to give you 12 volts and should not matter which battery. Just use your meter to double check.
With the batteries wired for 24V you can only get 12V in one place, it will come from the positive post that has the jumper wire from the negative on the other battery.Quote:

Thanks Justin I will use the one that the negative of the TM is on. I just connecting the nema power and a radio for now, later the livewell. Don't want to drain the start battery.
Remember that 24v pulls equally from both batteries. Whatever you run down on the one battery will not be made up by the other. Your TM will only run until one battery is dead, then its done. So running down one battery with electronics and livewell pumps is not good on your system. A better idea would be to get a dual purpose battery for your starting battery, with around 100ah in a 27 dual purpose there is little chance of running it down to where your motor wont start. Ive ran mine on electric only lakes for a week, then started the motor just fine.
