Be sure and put a flywheel diode on the air valve coil John. The contacts of that teeny little relay will last many times longer. And the relay driver on the 7i92 should be checked to see if the coil is missing a flywheel, and add a 1N914 if there isn't one. But I expect Mesa has that covered though. > > Never seems to end does it? > > > > John > > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
