DC 12V MOTOR CONTROL . FWD , REV , SPEED CTRL , 4WD , BRAKE.
ammarabbasi,
Move the wires on the break pushbutton so it's across the motor terminals...not the battery terminals. For better long term life for your pushbuttion, add a low ohm/high wattage resistor in series with one of the pushbutton wires. In the Fisher-Price Power Wheels (**broken link removed**) they use a 0.47 ohm/10 watt resistor. This limits the breaking current, saving the switch contacts, and provides more gentle breaking action. The higher the resistance, the slower the breaking action...the lower the resistance, the more abrupt the breaking.
