Challenge Getting First Bedini SG to Run

[aaronium112]

Hi guys,

I'm having trouble getting my Bedini motor to work.
As soon as I connect the primary battery my transistor starts to get really hot.
Also I do not hear the thud when the primary battery is connected.
I've attached pictures of my circuit.

Hi, welcome to the forum. The first thing I would do is check your transistor, it sounds like it has blown.

John, it does seem to be blown. I changed it and then promptly blew the new one.

Ok, you have something hooked up wrong then. Please recheck the circuit before replacing the transistor again.

If you watch this video, you can skip to the circuit installation. Peter explains how to hook up the wires to the circuit.
Even though you don't have this kit, you might find that section helpful to you.

I'd start by disconnecting everything and make sure the wires on your coil are not shorted together using a simply ohm meter between the different wires.

What about using a breadboard to connect the circuit?
It seems like there could be a lot of current in the output section.
My breadboard is only rated for 100 mA.

There is a circuit board that came with the kit.
However the components don't fit in any obvious way (specifically the transistors and switch).

Can anyone point out how to plug the components into this circuit board?

You can use your breadboard to get the machine running and then trace out where the components go on the circuit board. Note that that circuit board does not have a provision for the switch or potentiometer.

try and get the machine to run with just the master coil, the one with two windings on the same spool. If you follow the circuit diagram you should be able to get it to work.
