Lightspeed ignition problem

[algrajek]

Hi all:
I have the Lightspeed Plasma 2+ on my O-360. i have the Lightspeed on the top plugs and Mag on the bottom. After 350 trouble free hours, suddenly when doing a mag(ignition) check, the Lightspeed is not working at all! After looking at all the wiring and doing what Klaus advised, still no luck.
Has anyone had a similar problem. I’m stumped.
Thanks
Nordo

Has anyone had a similar problem

yes, I've had... dual LSE II here. So one system wasn't working, the other one was
Guess what, all resolved once I realized that the CB for that very system was out. Why? well, not going into detail here, but suffice to say that on the last flight I thought of disabling a device, but pulled the wrong CB And forgot about it...
Once this one was pushed in all back to normal.
Now, 2.1Kh later, and counting, the LSE Plasma II has not missed a beat.
