It has been years, probably 7 years since I have been one here, amazing resource, hope you guys can help me with me sure up....
To make a long story short, my sons little power wheels electric car is 12v. I figured out the wiring diagram but obviously missed something.
My goal is to add another 12v batter with the same Ah rating as the first, and use a switch to switch between having the 12v batteries in parallel(for double drive time) or series for 24v for a quicker top speed.
Please ignoring all the safety issues, or frying the motors as I will be ensuring this is a safe toy, but please help me figure out where I went wrong with this wiring.
What is happening after I wired it all up, is when the on/off toggle if off(open), and the system is in parallel, every seems to work perfectly. The problem happens when I toggle on the circuit, and one relay starts chattering and only delivers 3v or so to my motors.
I suspect I might be missing a diode but have burned my brain out trying to troubleshoot this.
I also assumed the primaries on my relays can handle 24v, if I am wrong I will just wire a resistor in series to drop the voltage closer to 12v(what I am thinking)
Please enlighten me guys, I know there are guys much smarter than me on here. Thank you
