(Charlie England) ________________________________ Message 1 _____________________________________ Time: 04:43:16 AM PST US Subject: Re: RV-List: Lightspeed EI Phase check From: Michael W Stewart 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 expla in 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 Kevin Horton To Sent by: RV-8@yahoogroups.com, owner-rv-list-ser rv-list@matronics.com ver@matronics.com cc Subj ect 06/15/2008 11:58 RV-List: Lightspeed EI Phase che ck AM Please respond to rv-list@matronics .com 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.

Dean, The shaft connecting the two control sticks maybe hitting on the top portion of the rib web. I had that problem with my RV9, and I needed to do some of filing in order to get full movement on the elevator control stick. Hope this helps.

The elevator bellcrank spacers need to be adjusted so the lower pushrod goes thru the hole in the bulkhead without interference through the whole range of motion AND the upper pushrod does not contact the vertical support when the stick is full forward. I think the asymmetry was because of the upper pushrod and that cone adapter needing to clear the center support. Whatever combination of spacers/washers gets you the clearance for both is all you need. The -6 is also subject to builder variation which has been engineered out of the -7. Sounds like you got it just right.

He lives in the certified airplane world but ....... The unit must be certified under either TSO-c129 or TSO-c146, be installed in the aircraft, and be approved in that aircraft on a 337 via either STC or field approval (if no STC for that aircraft exists). No TSO, no IFR approval. Since I'm planning on using the Odyssee (http://www.mglavionics.com/html/odyssey.html) glass panel with it's built-in WAAS capableGPS with RAIM ....... there's no TSO. Those of you with glass panels that fly IFR with a built-in GPS ....... did you use a certified GPS as backupor wing it ..... pun intended :-D .

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?

BUT! the unit MUST function to all the standards of the TSO. That includes not just RAIM but also the way the approaches and waypoints are handled and presented, and sequenced. My guess is that the Odyssey would not meet those standards. You may be able to make an argument that it does meet the standards for and en-route IFR GPS and then you could use it to substitute for DME and flying point to point - but you would have to document how you verified that it met the standards for en-route IFR GPS. You also have to be sure that the database points for the DME on LOC approaches are the same points used in the certified units (ie.. DME to the LOC and not the 'airport' etc). But really, if you want to fly precision GPS approaches don't mess around and just get a certified unit. Or save the $$ and just get a nav with LOC/GS. That will cost a lot less and get you in to almost anywhere. Think about how often you are really going to need/want to fly approaches to the lower WAAS minimums. Sometimes, but very very rarely.

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.

Those who have gone before, When is it ok to rivet the F-721A's ('forward canopy deck', @ instrument panel) to the longerons? I've fit all the stuff related to the F-768 sub panel components but I'm waiting (as the instructions say you can) to rivet that assembly into the fuselage. I'm ready to start fitting the canopy frame, but that ain't happening unless I either rivet the F-721A's to the longerons or take them out completely. The earlier instructions describe 'fitting' them, but don't specify actually riveting them in place.
