Coil testing - external coils

Coil testing -external coils Doing these tests was pretty fun and while not very scientific…well, not scientific at all…it was neat to see if there was any difference in what the spark looks like from each coil. From what I saw it looked like the spark from the Mallory 29440 was the weakest and it was a purplish color whereas the others had a blueish/white spark and they seemed stronger. One thing I didn’t show in this video is what the spark looks like with different spark plugs. I have some racing plugs without a resistor, and I have regular plugs with a resistor. For those of you who race, you might want to keep an eye out for one of my future videos on spark plugs. Anyway, I was able to find the coil specs for each of these coils so here they are: Mallory 29440 Inductance 7.5 mH Maximum Voltage 49,000 volts Peak Current 66 mA Primary Resistance .6 ohms Product Type Coil Secondary Resistance 11.3K OHMS Spark duration 3,600 uS Turns Ratio 94:1 Crane LX-92 Inductance 1.7mH Max voltage Peak current 510 mA Primary resistance .230 ohms Secondary resistance 910.00k ohms Spark duration Turns ratio 60:1 Accel 140003 Inductance Max voltage 45,000 Peak current Primary resistance .5 ohms Secondary resistance 8.6 k ohms Spark duration Turns ratio 80:1 MSD 8225 Inductance 3.5 mH Max voltage 42,000 Peak current 200 mA Primary resistance .31 ohms Secondary resistance 9.2k ohms Spark duration 200 uS Turns ratio 70:1
