[Healeys] Petronix Ignitor

[Alan Seigrist]

Jonas -

Probably most of the people getting the low speed miss are not using a
ballasted coil.  If you have a 4 cyl motor, you have to get a 3 ohm coil to
go with the Pertronix.  Simply swapping out the points is not enough.  If
not, the EI unit will overheat at idle and start misfiring.  If you have a
high energy coil like a Lucas Sports coil, the problem will only be worse.
 For whatever reason, Pertronix does not do a very good job of telling
people that if they buy the original Ignitor module, they need 3 ohms of
ballast in the coil.

If you buy an Ignitor II module, then a low resistance coil will work fine.
