When fuses blow it is because there is too much amperage flowing through the wires. An amperage increase is normally caused with more powerful motors and/or increased voltage. Healthy Power Wheels wiring can handle 775 motors and 24 volts. Think of your wiring as a highway that amperage flows along from homes (your battery) to your motors (a Hillary Clinton Rally). The switches are intersections that slows the amperage as it decides which way to go. Now a Donald Trump rally comes to town (bigger motors) which causes more amperage to flow. Now your intersections start getting backed up a little. Now if your switches are older and worn it's like having potholes in the road and Bernie Sanders in the crosswalk. The amperage starts to backup. The fuse is like a rickety wooden bridge that when the traffic backs up onto it causes it collapse. The same thing occurs when you increase the voltage which is like adding more homes with crazy people trying to get to the rally.
In the end, it's all Obama's fault.
Now in the event that you've replaced your switches and the contacts in the white plugs are healthy you should look to what could be holding the motors back. Putting too many shims on the rear axle so there's no play, a bent axle, rubber tires, increased tire diameter, are all things that make life tougher on the motors which makes life tougher all up the line.
