I have a stock 6 volt ignition system. Replacing the coil?
Can i use either a 6 volt or 12 volt coil, or do i need to go 6 volt only??
Thanks for your advise and wisdom, always most helpful and sometimes very funny!

you need a 6V coil on a 6V system.

A 12V coil has an internal resistor imposed on 6V windings, and thus your primary resistance will be too high

why not get a 6V coil directly from FSI ignitions? they are one of the few sources left of American made 6V coils

6 volt coils are available from any Model A parts supplier.

yep and u will prolly get an offshore coil.
notice i said American made
unless u don't care

My first choice for a coil would be a good original coil, which Bert's in Denver would most likely stock.

Any 12v coil that uses an external resistor will work.

NAPA will (probably) have a coil and I (and others I know) have had VERY good performance from their coils.
