Peter,

i had the same problem, and i first started with soldering it on the  Board as posted here http://code.google.com/p/ardupirates/wiki/Magnetos, and i was getting similar values as as you posted. Then i tried it away from tall electronics and screwed by the holes in the excess tab and the screws themselves were metallic and were the cause of  the sensor to do the same as you mentioned.  then I removed it away from all metallic abstraction using double sided tape and tie wraps and that did the job. Depending on where you buy your electronics some of the solder or components used will have some metallic materials that will cause your magentometer sensor give different readings.

 Also here is this post From Jani one of the Software developers in the adrucopter Team. HE is really friendly and i think he will answer some of your questions. I know him Personally as he lives not too far from where I live.

It might not  be a professional respond but it all worked for me at the end... hope its the same for you... 

 

Good luck

Romero, 

 

Thank you for the suggestions - I will watch the video and see if I can resolve the problem. 

 

I am not convinced that the problem is caused by magnetic interference for two reasons: 1. The Oilpan with the magneto work fine on my Arducopter APM, 2. It makes no difference if the Olipan is fitted in the aircraft or removed with its APM to the bench - the problem is the same.

 

I think the problem is to do with the offset values which are stuck from the old faulty magneto. The xyz values I reported look as if they could be resolved correctly. Whether this is caused by my changing from a 5843 to 5883 I am not sure.

 

The solution I will try is to reset the EEPROM to try and clear the offset values and then see if that cures the problem.

Solved!!

 

Reloading the Arduplane software and setting up from scratch has given me a working magneto.
