Default Re: 12v items hooked up with 24v setup

With 24 vdc its two 12vdc batteries in connected in series . aka the one battery #1 negative attached to second battery #2 positive. And the 24vdc power to the 24vdc electric motor is first batt#1 pos terminal connection and second batt#2 negative terminal connection attached to 24 vdc motor.

For your 12 vdc system.... connect neg/ground to the SAME neg the 24vdc motor is connected to. You need a common ground. That's it or problems.

The positive of your 12vdc gear should be run from the positive of the SAME battery that has the boat wide common ground/negative.

There! Do not connect batt #1 negative to post to ANYTHING but the positive post of batt#2.

PM me if you have any questions?
