can anyone help me with a similar circuit?
I need to build a delay timer for about 20 seconds that controls a 12V DC power source activating a relay. This system will be activating the light harness on a motorcycle so voltage may peak to 13.8V at times. ITs only an issue at startup, hence the 20 second delay, power must be uninterrupted from that point on.
Basically the circuit will get power of 12VDC at time 0sec and then 20 or 30 seconds later it needs to activate a relay and keep it on as long as the power source is active. When the power source is removed, then it needs to reset and do the same thing all over again when the power returns.
Thanks in advance.
