So here's the new ESC from ML Toys: 
Theres some prime real estate for this, in the back next to the batteries:  ...yeah, that looks good there:  So lets start wiring this thing up. It comes with some very nicely made wiring harnesses. Crimped, soldered, and heat-shrink. One for batteries with a 40a breaker built in, and a second made up for the motors. Different plugs so you cant get it wrong.
Simple enough install, and plenty of room to route the wires cleanly  Now, in a Power Wheel the battery would be under the hood, and you unplug them to charge them. But since the batteries are under the seat, we need a way to charge them. So lets tear into the harness and examine the original charging port:  So the switch is in series with the battery. A closer examination reveals contacts inside the switch, that open when the charge cable is plugged in, cutting power to the vehicle in the process so it cant be turned on while charging. Clever.
A quick test with the voltmeter verifies this:
So this was a pretty clever solution to a problem, but im not sure that it can handle the power, considering were now putting 3x more voltage through the contacts. Plus the teeny tiny wires they used. So im going to reuse this to charge, but im going to wire it direct to the battery, and then just remember that the Bronco has to be turned off when charging.  So that covers the batteries and the motors, now its time to move on, and start laying out the pedals!  Comments are closed.
