Pulsar Friends,

A week ago, just prior to take off, I did a mag check and the engine would die on one of the mags. I since have been trying to diagnose the problem and got suggestions from Rotax techs at Oshkosh AirVenture which I was planning on attending (drove).

Swapped mags, and the problem remained on the same switch position so both mags were okay.

The pick two pick ups both measured 168-170 ohms to ground, so they both appear okay.

The charging cable's white wire coming from the engines rear coils, one showed a ground connection, the other was open.

I just talked with the Kankakee, Illinois Rotax shop, and he said, the open white lead disconnected and to access the back end of the engine, the engine has to come out.

Has anybody experienced a similar problem and did it take pulling the engine to open the back end to fix the problem?

Thanks in advance to any advise.

Best regards,

Ron

HI Ron
Had the same sought of problem on our Pulsar 582, turned out to one of the wires from one of the ignition modules had chaffed against the cylinder head where they run behind the HT leads, was very hard to see but was just enough to ground out the wire!
  best of luck, did take a photo of it if I can find it I will e-mail it to you.

All The Best Steve G-BUSR
