Well Joe, I never operated this demo construction for very long. Your unit obviously got overheated. Did you have it fused? I'm not sure if my ignition coil is oil filled. If your coil is still functioning, you could try wrapping some heat sinking fins around the case. I assume your coil was rated at the same voltage as the supply voltage. You could also reduce the current with a high wattage resistor in the primary, but that would also reduce the spark intensity. To use a six volt battery, use a six volt flasher and six volt coil. When that capacitor discharges, it pulses the primary winding, thus producing an output in the secondary. I hope this helps.
@@ernestweaver6182 the run time is too long using a blinker relay, mine got boiling hot and puked out the oil in the first hour. trying a relay oscillator now to reduce the duty cycle.
@@jw5155 Yes, youtube "relay oscillator" and youll find vids on how it works. You jumper two pins and then use a capacitor across another two so that it charges up then latches, and then discharges and unlatches. The frequency is very high. I would start around 500uF. The voltage rating of the cap doesnt effect the frequency but it does alter the spark output. I was able to use a little chinese boost convertor to input higher voltage to the automotive coil but they heat soak and become unstable. What should have been 18-30vdc turned into 90vdc and an output of around 13k vdc on my fence charger from the coil secondary. The voltage spikes feeding back through the coil wires were so high i was getting shocked through the insulation. I sure wouldnt wanna get hit by the lighting bolts coming out of the plug wire. Might be lethal.
ru-vid.comwZRd1xorzyo?feature=share Forgot i had a vid. Thats around 90 vdc input from a marine 12vdc battery with a boost convertor. Probably hazardous to livestock. I have not succeeded with one long term yet. Its on the backburner. I did have a portable goat fence up for a day running the marine battery with this same setup less the boost convertor and the real voltage on the fence as far from the charger as possible was around 1200volts. Had an escape happy hog in it for a day and saw her get a few snout zaps but it didnt take her long to plow dirt onto the bottom wire and then push it up where the first zaps landed on her fat head and didnt bother her. Goats would just ground it with brush im sure. So i knew it needed more volts and the adjustable boost convertor worked but had thermal run away. I never did find a cheap, stable convertor to try.
