Racinrc14 -> Zenoah G20EI Ignition no spark (11/8/2012 4:35 AM)

Hello all,

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.

Sounds like its toast. You can get a replacement for it here http://www.rcextremepower.net/ignitions.html thats better than the stock unit. Its not a power hog like the Zenoah and it does not weigh as much.

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

If the ignition is in fact toast as I suspect it might be, do yourself a big favour and get a replacement plug and play RC exl unit from Milton at RC Extreme power and go enjoy your G20.

i would follow BCCHI suggestion first,he made these ignitions for years.

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.

3 amps?!? Holy crap! I might just order one of the others anyway...



Racinrc14 -> RE: Zenoah G20EI Ignition no spark (11/10/2012 12:25 AM)

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!
