My RC car uses 2 relays (9 V, SPDT) for it's forward/backward movement, as image below indicates:
However, RC car isn't able to be driven anymore. Specifically, servo works fine but motor can't spin. Instead, there is a sound came from the relay(s). I 'm thinking of replacing both relays to see if it works.
RC car powers up from a Ni-Cd battery (8AA) 700 mAh 9.6 V.
My question is:
Can a 9 V relay been replaced from a 12 V relay? In other words is it possible for a 12 V relay to be energised in this case?
