Dave,
The problem I had was initially hard starts. Eventually culminating in a completely inop Left mag on the mag check during runup. I had the warning light illuminated in the cockpit as well.
The answer to your question is I don't know if it was the control box or the the mag itself. The A&P says it was the mag. THe whole system had been installed for about 12 years, but the system only had about 375 hours on it.
I recently purchased the aircraft. Prior to that it was hangered near San Francisco. Currently I am based out of Lakefront in New Orleans and the plane is tied down outside. I wonder if the drastic change in climate might have had something to do with the problem.
Couple additional things. I had had a few episodes of hard starting. But since the aircraft was new to me, I chalked it up to my improper technique. I think there were probably other clues leading up to the failure that I just didn't recognize because of my lack of familiarity. When the A&P took the LASAR control box off the firewall, he noticed that it seemed to have some water in it. You could hear it if you shook the box. That is something that there was no way to know until we removed the control box.
I am planning on trying to resell the components to recoup some of my mx costs. Hopefully that will make this whole episode a little less painful on the wallet. Champion quoted my A&P $2300 and 4 weeks for a left mag. I replaced the whole system for about the same price which also included installing a slick start to replace the vibrator.
Hope this helps. Let me know if I can help with any other questions.
Jim
