I was flying my BME 50/H9 260 today and just after I started it up for a last flight it quit. I noticed that the ground strap/wire to the spark plug boot was broken so I packed it in and went home.
I fixed the wire and I still don't seem to have spark.
I took the plug out and grounded it to the engine cyl. and spun the prop with an electric starter to get some rpms going to check for spark and nothing?
My question is: Is there a way to check out the ign. box? I know the battery is charged and all the wires/connectors seem OK.
Is it possible I burned it up when the ground wire broke to the plug cap?

If I did mess up the ignition box are others from other manf. the same and interchangeable or are there different timing curves etc.?
Would going to a different manf. ignition box maybe improve performance or reliability?

Any tips or suggestions greatly appreciated.

You just need a new sensor...When the ground strap breaks the spark goes to the closest ground, in this case it's the sensor...You should get a spark when you flip the ignition on and off...If not, the ignition is bad..Not very likely....A different ignition won't make any difference....[8D]

If the ignition is CH, they have the sensor already mounted on the correct copper bracket for the BME. If you want to cement the sensor onto your existing bracket, they use JB Weld. I had to replace mine once, and as I recall it was somewhere around ten bucks.

Where do you get the sensors? I went to the BME web page but couldn't find any info about replacements. I guess I could call or email them.
Does anyone else sell just the sensors?
It is the CH Syncro-Spark system I believe.

Does anyone know if these are the same kind of sensors that heli governors use. I have a few heli's and was just wondering.
Are the sensors for the gas engines all basically the same?
