I just fired up my Lyc 540 for the first time configured with Electro air ignition on one set of plugs and a Slick mag on the other. I noticed the mag was not firing. I verified this with a strobe gun. I plan on replacing the unit which has been dormant for about 4 years, just sitting on the back of my engine. Anyone know of what might have gone wrong with this new unit, or how I might get it fixed?
Thanks,

The mag wasn't firing or the CDI (the other "mag")?
I have used dual LSE CDI's for over 200 hours with no problems so far. If it's the CDI not working, perhaps time to move up to LSE's.

If a mag doesn't fire at all, it is grounded or the points aren't openning.

Is it an impulse coupled Mag?
Did you check the gap on the points? Some times crawlies can get in there an hold the points open.... That's where the term bugs in the system comes from.
When the engine was mothballed you didn't happen to put an extra ground on the P-Lead? I usually will put my own "Lock out on the P-Lead if I'm going to work on an engine.

Jim,
As an A&P I will let you in on a secret don't take the magnet apart until you take the ignition harness off of it and let it sit open for 24 hours because it may have some moisture. I would also get yourself a timing box and hook it up to the magnet and turn the engine over to see if the points open and close and are not grounded. Make sure you P lead is not grounded when your ignition is on. If no results come from those procedures only then would I open the mag. They usually mechanically do not fail from sitting. Only real thing that could happen is moisture in it and if they dry out normally they will work fine. If not the points usually need replacing and is a very simple producer that only requires a small amount of tooling and some time. You have to be careful and take your time doing it but its nothing you can't do yourself.
