I have a brand new Zenoah G20ei. I wired everything up as per the instructions. Thought I had done everything right. What I discovered was that I had used an old switch (probably Airtronics) for the ignition battery that had the positive wire on the outside of plug, and turned the ignition on before I realized it was backwards. Of course, now I have no spark. I have tried to get the ignition to fire on the bench by plugging in a fresh 4.8 battery (and using the correct polarity) and grounding the plug against the jug and switching the ignition on then off. This yields no spark. Have I fried the whole shebang by reversing the input voltage? I'm hoping to avoid having to buy a new ignition, and Adrian at CH can fix me up for about $100 bucks, but I was hoping maybe an expert here can maybe pick up something I'm missing and save my bacon. Thanks in advance,

-Tommy

Probably blew you hall sensor. Try that first. Adrian has them.

This was in the FS forum http://www.rcuniverse.com/market/item.cfm?itemId=880829

I thought that's what I was checking when I switched the ignition on then off. If you get spark when doing this doesn't this indicate a faulty hall sensor? I have a replacement Zenoah sensor on the way, it was cheap enough. Is there a way to troubleshoot the hall sensor?

OK,I am brain dead sorry. I was thinking C&H or RCEXL.I do not no about testing the Zen ignition except it draws close to three amps.

Status: offline 		We have ignition! It was indeed the sensor as BCCHI suggested. So, for Zenoah ignitions, turning the ignition on then off with the plug grounded to the crankcase is not a definitive check of the hall sensor as it may be for other ignitions.

Thanks guys!
-Tommy
