Yeah, that's what I need too. I made a circuit diagram from things that others suggested, and made a few changes based on some advice, but when I built the circuit it didnt work. I dont have the electronics knowledge to trouble shoot it... if you know what you're doing with electronics, maybe you could have a go at it, and see if you can get it to work. Otherwise, tell me what you think should be done, and I'll have a go at it (:Originally Posted by Acree
Basically, the first relay works, i.e. the 12V will switch on the inverter, and switch it off when the 12V is cut, but but the delay timer part (with the second relay, resistor & caps, and the transistor) doesnt work.
This was the circuit I drew, except that it was modified like this:
- All LEDs were omitted,
- The 470K ohm resistor was replaced with a 470ohm,
- The 9.2k ohm resistor was replaced with a 1kohm,
- All diodes were replaced with 1N4001.
