I thought when you went electronic, you did away with the ballast resistor?
I've got to do mine soon, so I'm interested too.

A ballast will help it live a bit longer , ever seen an orange box leak all it's guts over the bulkhead.
Better still , hook up an MSD/Mallory.

petronix ignitor is a hall effect trigger. magnet in collar approaches the detector and the signal is used to stop the flow of leccy to the coil.
neat easy to install.
semi conductor version of points....but it never wears out.
also works in dissy that has ware in the bushes that would be useless with points
have used one in the past and from a no messin point of view Excellent.
doesn't get you much of a gain over points mind in the spark power league apart from the bit gained back by having no condencer. installed in a system in good condition no probs

ballast resitor is there in all situations
just some of them are a sperate unit like on a mopar
on others the ballast resistor is not a sperate unit. the resistance is the internal resitance of the coil.
ballast resistor used with coils that are ostensibly 9 volt coils.
no ballast resitor (unit) used with 12 volt coils
(use a ballast resitor with a 12 volt coil and you are running your coil in the region of 6 volts. Not good)
however.......if the ignition module you use is fed its + volt supply from the 9Volt source off the ballast resistor it won't necessarily like running at 12 volts.
howerver in this day and age it bloody well should. most automotive circuitry is perfectly happy on 9 -15 volts DC. (but this is where my knowledge of the 4 pin ballast resistor used on mopars with elecronic ignition is lacking)
it needs to be to cover the variations as the battery charge changes and the alternator kicks in.
on a points car with a 2 pin ballast. bypass the ballast and run a 12 volt coil
1 thing less to go wrong.

& buy yer points by the shedload.

well yeah
suppose a new condencer should be part of that equation
tis ya point saver.

ah just thought
makes no odds
the resistance in a 12 volt coil is still in circuit so the current is still limited as it was with a 9 volter and a ballast
no issues other than what you expect with the use of points. i.e they will still arc once the little charge sponge called the condencer is full.
the bigger the condencer the longer ya points last but the samller the park you get at the plug
thems the breaks
