Tech West Racing Services MSD Upgrade

[Jeff Niceswanger]

Hi Pat
I have stumbled on a Tech release Addendum quoting that the PN 7530T ( among others) will " shut Down unexpectantly" if a resister is not added to the "power on" line while using 16 volt battery's if the hand held PN 7550 Monitor is left hooked up..It states that if your unit has R1 or R2 stamped on the end panel,updates are already installed and this resister is not needed. Mine is stamped R4. I'm taking it that this is revision 4, and the other ones noted were revision 1 and 2...But wanted to verify. Thanks for you time and info, Jeff

Pat, wondering if you could give me a hand with an ignition noise related issue?
