I have a few questions relating to Pertronix distributor modules and the use of an MSD BTM:
- I understand that any of the MSD boxes are not compatible with the Pertronix Ignitor II or III ignition modules due to both the MSD and the Pertronix modules have rev limiter functions. Is this correct?

- Due to the above understanding, I replaced my Ignitor III module with an Ignitor I. I understand that these are compatible with an MSD BTM. Is this correct? Why was this unit dropped?

- I'm looking at an NOS MSD 5462. I know these haven't been manufactured for several years. Due to this and if I have issues or questions, would I be able to rely on MSD for help and technical support? Thanks, - Greg
