Try to put something in between the sensor and crank case, 0.5-1mm and time it again.
The problem should go away.
I need one of those problem sensors, Carlos please send me yours.
I think that that is the SMT version.
For several good months Rcxel do not use the SMT sensors any longer .
I talk with Liang couple days ago and I made him aware of all this.And he wants me to take care of all RCxel related issues, warranty of units or any other complains. They all going to be replaced with CH units USA made...on the kitchen table each one by hand...by me and my wife.
They use the same sensor I use for the last 4 years and Bill for....LONG, LONG time, after the Panasonic chips become obsolete.
A1104 is the part number , go ahead google it and buy it on your own if you want to.
The adjustable sweet spot is rcxel part and it is good when you have to make some hard conversions.
Klaps,
send me your address at
[email protected], I will send you a replacement. Before that please go ahead and try what I suggested, increase the space between magnet and sensor.
Thanks
Adrian
Adrian,
Thanks for all your hard work regarding this problem! Adrian, you are the man and the first to bring any word directly from Rcexl regarding this issue.
I read your post regarding increasing the spacing between the magnet and sensor and already being in the shop, I dug out my bag of double spark sensors. Set them up on an ignition for testing and started washering the sensor away from the magnet on a DLE 61 that was also sitting in front of me. As I increased the distance, the double spark was less frequent but it was still there all the way until the sensor was spaced too far away from the magnet to trigger it at all. With that in mind, I don't believe that spacing will resolve the problem on the sensors that exhibit the problem. I've had (3) known bad sensors now that exhibit the double spark.
Awhile back, I scoped the output pulse waveform from one of the bad sensors but sadly, I neglected to take a photo of it. I could draw an approximate example though I'm sure some of the detail would be lost in my memory. I could give you enough though so you could see where the problem is coming from. Its very difficult for me to believe the Rcexl factory has not experienced this problem or that they have not been overwhelmed with complaints. For my new engines, I just test the new sensors and replace as needed though every new sensor I have purchased in the last two years has exhibited the problem. Older ones are 100% fine and I bought my first Rcexl ignition shortly after they became available. The problem sensors drove me a bit crazy until I came across what the problem was and I believe it was suggested by or at least passed on by Milton.
