Hi, Im a new member and have been inspired by this forum to build my first sg and start experimenting. Looks so simple but I can not get it to run.Im using a skateboard wheel with four magnets ducktaped to it. I was using a 16 inch bike rim but changed to a skateboard wheel when I couldnt get it running. I have about 900 turns on the coil and am using a in914 diode with a 100ohm resister changed from 470ohm when it didnt work. I am using a 3055 transistor. I see nothing on the base and 12volts on the collector and emitter.
The coils are not shorted together or open. If I read across the diode I see a little over 100 ohms so Im reading through the resister and coil across the trigger side. My battery negitive side is my ground. I have no load on it and am using a sealed lead acid 12volt battery as my source voltage. Does anyone have any ideas? Thanks petey256
