Battery Sparks When Connecting Positive Terminal. With positive esc wire having a 1500ohm 2watt resistor pigtailed onto it. If you connect a battery to a length of cable there will be an inrush of current as the capacitance of the cable is charged.
You connect the circuit with the switch in the open position and then use the switch to turn the power. When hooking up the new battery I hooked up the positive side. When attaching the battery cables place the positive cable on first and then the ground cable.
You can get a spark connecting the negative terminal just as easily as connecting the positive terminal.
Bench tested starter motor at local auto parts shop and they said its fine. Then when I connect the ground terminal with the screwstud thing I get sparks. The battery cables can spark if the cables are installed in the improper order. Re-installed the starter motor.
