I was sitting on the runway doing a mag check in my 80 horse Rotax912.
I flipped the right mag switch to off and the engine died for about 2 seconds then restarted. Then died, then restarted. This pulsing death indicated that maybe I should not fly. So I'm down.

I didn't see anything in the CDI wiring that looked amiss so I pulled the toggle switch and had it tested. It was showing some resistance, so I bought a new one. I reinstalled the switch, same problem. I reversed the switches just to make sure, its still the right mag that fails.

Any ideas? I thought I would just send the module to a rotax facility and have it tested but, should I look for anything else first?
