I need to replace my bad coil today.
Currently using Pertonix 40501 but can't wait for shipping. Car is my daily driver.
Can anyone tell me an alternative I can find at the usual Azone, Pboyz, etc. (FWIW, called PB, NPA an no one seems to carry Bosch Blues either??) Independent shops are closed today
The coil you choose , depends on the System be it Pertronix or OEM , whatever :
The voltage feed determines the coil you want as the basic resistance across the small posts is critical and failure to follow this is what kills 99 % of the Pertonix failures you hear about .
If the car is 6 volts or has ballasted ignition , use a 1.6 Ohm coil , IE : ask for '75 Chevy V-8 coil @ NAPA and pay the extra $2.00 for the better , epoxy filled ~ one it'll outlast you and the car .
If the car runs straight 12 volts to the coil , you'll want a 3 Ohm coil like for a '69 MGB or a '74 VW Beetle
The epoxy filled coils tend to last longer as they're vibration resistant .
I've only ever found a couple bad ignition coils , mostly Lucas aluminum ones ,
