Components I have:
Arduino MEGA and NANO
12V Powerwheels battery + AA battery packs
Appropriate wire, terminals, crimper, etc
I need help wiring the setup in the title. I am trying to control a DC motor taken from a Powerwheels Jeep Wrangler through the pins of an Arduino. The motor draws 70A under normal load, and is brushed. I've been doing a lot of research online trying to understand how this would work, but I haven't found anything exactly like mine and do not quite understand how it should work. Namely, how do I connect the arduino, transistor, diode, and battery to the relay that I have? I should be fine with the code, like setting the pins to be HIGH, it's just the wiring that is troubling me. I also am not sure if I will be able to reverse the motors rotation with this (without an H-Bridge or expensive motor controller). Any help would be much appreciated, thanks for reading!
Here are some resources I have been looking at:
Here is where I got the figure for the motor's current draw.
