Posted: Sun Jun 15, 2008 8:06 am Post subject: Lightspeed EI Phase check

I'm having problems with the phase check on my Lightspeed Plasma II  

ignition.  I'm not sure if I'm doing the check wrong, or if I have a  

problem with the wiring, or with some component in the ignition.   

I've got a Hall Effect unit in the right mag hole.  The little green  

LED on the back of it is working, and it goes out when the crank is  

rotated through 5 deg after TDC (I've got 8.7:1 compression ratio,  

and this is what Klaus recommends).  But, when I try to check the  

phase, with the plug wires pulled off the coils, I can't see any  

spark between the two outputs on either coil.  Nothing.  Have I  

misunderstood how the phase check is done?



I've checked that the two coax cables are on the BNC connects of the  

ignition box, and that the other end is hooked up to the coil input.   

I guess my next check will be continuity of the two coax.  After that  

I'll check each wire in the cable that goes between the Hall Effect  

unit and the ignition brains box.



Any other ideas would be appreciated.



Thanks,

Kevin,

 As a test, plugs out, swing the prop, by hand or by starter, you should see and hear  a monster spark between the coil plug pins.

 If not, the next thing to do is pull the hall effect and check the gap on the fly bar to the magnet pickup. Its a pain but the instructions explain how to check the gap and what the gap should be.

 This was my problem when I got mine and a proper gap fixed it.

 Also triple check the voltage and gnd into the box. Id do this first.

 Mike

Mike,



Thanks for the info.

I've swung the prop briskly by hand, and neither coil sparks.  I've confirmed voltage and ground on the correct pins at the connector on the EI box.  As far as the gap at the Hall Effect unit  goes - if the gap is wrong, would the green LED on the unit light up and go out as you turn the prop?

I finally was able to get ahold of Klaus Savier, and he had the  

problem sorted out in about three minutes.  The electronic ignition is  

OK, but I wasn't doing the phase test properly.  I wasn't rocking the  

prop back and forth quickly enough.  Klaus told me you need to  

generate at least 2 pulses per second - that means two complete back  

and forth movements in less than one second.  Once I rocked it very,  

very quickly, I got the spark I was looking for.  Both coils check out  

OK.



I hope to get the first engine run done sometime on the coming  

weekend, weather permitting.
