yes it does, thank you...now the diode is another thing i wasn't sure of, the person that explained it to me told me it was supposed to keep the 2.4v boost from happening in reverse...though i wasn't sure exactly where to put it in the diagram
....
so now if i put the power sources in series, when the relay is switched, will the main circuit board of the car still be running on 7.2v will the motor is getting 9.6v?? and put the two power sources in parallel with a spdt relay?
and this part i didnt really understand..."A diode isn't required, but some kind of switch contacts are to turn the relay on and off." the relay is supposed to switch when a certain voltage is reached...so what are switch contacts??
