After my first flight, the left side Strobe light, does not work. After I checked everything, I called the Mfg. Aero Flash, and they told me it must be the Power Unit. I do not have now any warranty, as have purchased this, more than two yrs. ago. So I have to buy a new power unit...2 questions,1- any other place I can buy this, at a better price... Wonder why only on one side.. Finally, when checking, this light, I droped the red lens, that cover the light. Now I see that they want $15.0-0 for 2" red piece of glass.... Any suggestions on this also, as to where I can get this, for less than 15.00 plus shipping? plain robbery.... Thanks for your suggestions.

Then put the lower cowl on and the top so the top overlaps the bottom. Marked a line on the bottom using the top as a guide. Cut it there. It was a little more than the given joint in the cowl.

First, swap power supplies and strobes from side to side (not both at the same time!) to identify for sure whether it is the strobe or power supply that has the problem. I had a strobe to fail very early and upon close inspection, found a component of the strobe bulb inside the potting that was BARELY protruding from the potting and arcing to the grounded shell. This failed the strobe until I insulated the area and then the unit was again operational. Give the failed strobe bulb assembly a very careful inspection to make sure nothing is shorting to ground. I also dropped the red lens (VERY easy to do as you disassemble the unit!). I glued it back together with CA glue temporarily; 5 1/2 years later and I still haven't gotten around to replacing the lens. :-) Sam Buchanan (RV-6, 650 hrs) http://thervjournal.com ________________________________ Message 7 _____________________________________ Time: 08:53:43 AM PST US From: "Konrad L.

Have you swapped the left and right strobe connections on the power unit? By swapping the strobe connections on the power unit, you can make sure that the power unit is bad, not the strobe head (or strobe wiring.) > I do not have now any warranty, as have purchased this, more than >two yrs. ago. It may be just urban legend, but I have heard that you should not let a strobe unit sit unused for years on the shelf. Judging from your experience, I guess it would be a good idea to fire up and test your lighting system as soon as it arrives, just to be sure that everything works OK. > So I have to buy a new power unit...2 questions,1- any other place I can >buy this, at a better price... You might be able to get a good deal on a strobe power unit from Bill VonDane at CreativAir I know Bill sells complete strobe systems at a very good price, so I suspect he will sell you the power unit alone for a good price as well. I also know that he is very good about customer service and stands behind everything he sells.

I have seen things arranged such that the line T's into the supply line of one tank (the one not currently being used, say, the left). I have also seen things arranged so that the fuel purges back all the way into the tank which is selected. I have a few questions. I suspect that the perferred solution might be to have purge lines run all the way back to the tank. However, it does add weight (more fuel lines, more fittings, etc.) to the setup. Choosing to just T the line into the left tank, and always purge with the supply set on the right tank ... while not as elegant, is clearly simpler. It does require that the pilot always remember to set the correct tank if they perform a purge.

I have wondered if there is any risk of somehow siphoning fuel out of the tanks if I place the end of the purge line poorly. I assume that the purge valve, at a minimum, would stop any siphoning. If this is true, it seems that the simple solution would be to just add an AN fitting on the tank cover with no internal line at all in the tank itself. Is it that simple to terminate?

The primary reason is to circulate hot fuel out of the system and back into the lines between the tanks and the fuel pump to make hot starts easier. I have mine returning to the right fuel tank line before the fuel valve. If I start with the fuel valve set to feed from the left tank, the presumably hot fuel returns to the right tank as the fuel pump pumps from the left tank. I was also told that even if I started from the right tank, just running the hot fuel back through the lines and the fuel pump would probably be sufficient cooling to get things going. The other reason for the purge valve is to shut down the engine. Apparently the mixture doesn't reliably stop enough fuel going to the engine to stop it. Lots of stuff on this in the archives.

I simply routed the line from the purge valve to a 'T' into the vent line on my right tank. If you put the 'T' at the low (tank) side of the vertical loop of the vent line, the pump will send fuel into the tank through the vent with the valve on the "purge" setting. The vertical loop in the vent line will keep the fuel from being pumped onto the ground. With the purge valve at the "run" setting the tank will vent normally. If your tanks are full, your fuel selector must be set on the tank the purge valve will send the fuel to (in my case the right tank) or you will overflow the opposite tank. This will create a closed loop with cool fuel being sucked from the tank while the hot fuel is pumped in through the vent. If your tanks aren't full it doesn't make any difference. It will just pump fuel from one tank to the other. This has worked fine for me, but I have yet to do any hot starts in temperatures above 80 degrees. E-mail me off line if you'd like pictures.

You are right that some FI installations do return excess fuel the way you describe, and this is the line I am talking about. There are arrangements (as I understand it, feel free to correct me someone if I am mistaken on this point ... I'm still learning) where a "purge valve" is installed so that, particularly for hot-starts, you can cycle fresh fuel through the system prior to attempting to start. This way you can flush out any fuel which might have vaporized in the lines. As you cycle the fuel, it has to go *somewhere* and this is the return line I am talking about. To answer your question, if the issue were just one of handling excess fuel I'd say your suggestion would be a good one. However once you factor in the desire to flush hot fuel and/or vapor then it seems better to return it much further downline. And, yeah, I have wondered what this does to fuel totalizers since depending upon where you put your flow sensor in the system you might be pumping fuel through it (causing it to be counted as "consumed") when it isn't really being consumed. There was a thread of discussion earlier in the week (or was it last week?) talking about placement of the flowscan type sensors ... with someone suggesting that it could be placed just before the spider. The suggestion was that you could mount it there and cover it in firesleeve and it would work fine. Is that true?? This would seem ideal as then it would ONLY meter fuel that was headed into the cylinders, and nothing else. Enquiring minds wanna know. :) -- Dwight do not archive ________________________________ Message 24 ____________________________________ Time: 03:07:38 PM PST US Subject: RE: RV-List: Fuel Purge Line Question From: "Stewart, Michael (ISS Atlanta)" --> RV-List message posted by: "Stewart, Michael (ISS Atlanta)" I had one failure in my setup of the return line. This is purge line return not excess return. My return line was alum tube from valve at the spider to the rear baffle. Then flex line to the firewall. I delevoped a hairline crack in the alum line which caused air to return to the left tank supply line. Engine quit, switch tanks and she was back no big deal. The killer was I spent a week trying to figure out why my fuel was leaning out to quit. Pulled tanks, cleaned em, replaced all supply lines. By happen stance my buddy grabbed the alum purge return line and noticed the crack. I learned my lesson and now have flex lines AND the purge goes to my tank vent instead so as to never have anything in the purge put my supply out.

I do this because the airplane (- 6) is out of balance laterally with just me and full fuel, so burning the left tank first tends to balance the load quicker. Doing it this way means that the purged fuel is going to the un-selected tank. I originally tee'd into the vent line but had to change it because it tended to pump fuel out on the ground, probably because it was pumping into a smaller line and the fuel went both directions in the vent line. Just be sure that the totalizer is turned off when you start and you won't have any errors due to the purged fuel - although, the amount of fuel that is purged shouldn't even be noticeable in the total fuel burn so I wouldn't worry about it.
