12 – 120 V Inverter
Ever needed a low power 120volt AC power source for your car, van or truck? Well this circuit should do the trick for you. This is the design for the problem. The circuit will supply 15 watts of AC power to a device. The circuit should power lamps, shavers, small stereos and small appliances. If you draw to much power the circuit will shut down all by itself.
The output of this circuit is a square wave so there may be some noticeable hum on audio units plugged into it. To reduce some of the hum increase the value of the output capacitor which is at .47uf now. That transistor in the circuit are high power PNP transistors. Radio Shack part number 276-2025 are good ones to use or TIP32. The transformer is a 24 volt 2 amp center tapped secondary Radio Shack part number 273-1512 or equivalent.

BMW E34 1988 – 1995 Wiring Diagrams
BMW E34 1988 – 1995 Wiring Diagrams. Figure 3 shows right-side (left) and front views (right) of the fuel pump assemblies we’ll be installing Wiring Diagrams . On the pump at left, BMW E34 1988 – 1995 Wiring Diagrams the fuel level sender is at the lowest position. On the pump at right, it’s in roughly its mid-range position. The clear flexible lines from the fuel pumps (the silver cylinders is mounted to the plastic body via a rubber suspension) exit through the top of the plastic housings via an 8mm bib, and are capped off with black plastic plugs when new. Not visible are the 12mm bosses for the return lines, which simply dump fuel down the back of the plastic housings. The fuel pump assemblies do not employ a keying scheme to limit installation to a particular orientation. However, the dimensions of the fuel tank and the geometry of the fuel pump assembly force the fuel pump assembly to be installed in only one orientation – with the fuel pump pickup pointing down and towards the rear of the car.
