      This my be a stupid question but here goes. I was thinking about taking my 
      newly bought RV-8 on a trip where it will have to be parked on a ramp for a 
      few days. I did not get a canopy cover with the plane and was wondering if 
      the -8's take in water when it rains? Also does anyone use the Light travel 
      canopy cover that Vans sells and does it keep out the rain?
      
      Thanks,
      Matt

      I have seen a -8 ... ;-)    but have no clue if they leak.  I may still 
      help though.

      Most of the light weight covers shed the rain by containing it in the 
      cover so it's absorbed in the cloth and drains instead of impacting 
      where the canopy meets the windshield.  The heavier covers actually 
      repel the water so the underside stays dry.
      
      I'd recommend a good cover if you're going to leave the airplane out 
      .... google 'canopy covers'.
      However, you can use the lightweight cover and just use the blue 
      painters tape to seal underneath the cover.  BTDT.

      I used the Vans lightweight cover while parked during a frog strangler on my way
      to OSH in 2010. It worked well.  I was concerned about leaks around the front
      baggage door, but that was not an issue.

      I used the light cover on my 8 and thought is was fine.  I'd get it again.
       I don't think I had any canopy leaks.  I did get some water through the
      NACA vent during a storm though.  Plug it with a closed cell sponge or
      something.
      
      I also put some of those plastic cling shades over each fuel cap to keep
      the rain out when parked outdoors.  The same ones that can be slapped on
      the canopy for some sun relief.
      
      Safe travels.

      Listers,
      
      I have put 1175 hours on my RV6 over the last 10 years and I'm currently
      having serious alternator problems. 
      
      I have Vans "steam" engine gauges including an analog ammeter and voltage
      meter. While cruising at altitude about a month ago I noticed my ammeter
      start to "quiver" a lot. After dancing back and forth from neg to positive,
      it finally went solid to the negative side. I figured I lost my alternator
      but wasn't too concerned. I turned off my strobes to save battery life and
      headed home. My battery had plenty of life for my radio and transponder. 
      
      I removed my alternator, had it checked (it was dead) and bought a new one. 
      
      After about 5 hours on the replacement, the same scenario occurred. I talked
      to others more knowledgeable than me (just about everyone) and elected to
      install another one just in case it was a bad alternator. You guessed it;
      same thing happened. BTW, before changing out the first alternator, I
      checked all electrical connections to see if I could find anything loose and
      could not. The only thing I found was the nut attaching the heavy gauge line
      from the positive battery to the master relay was snug but not tight. There
      was also a little residue on the master relay that looked like it may have
      'arced' at some time. I sinched down the nut and hoped that was my problem. 
      
      I am now on my 3rd alternator in a month. This time, I bought a "Plane
      Power" one from Vans. Yesterday, my ammeter started the boogie dance again.
      I shut off the alternator by turning off my field switch on my panel for a
      while and periodically turned it back on to charge the battery. But after it
      was on for a while, the ammeter started to quiver and dance as it has done
      before just before it failed. In all three cases, when the alternator is on,
      the battery is showing 14.5 volts. Also, all 3 alternators have internal
      voltage regulators.
      
      
      Any and all suggestions / advice is much appreciated.

      I suggest you first look at the alternator ground path.  Instead of relying o
      n mounting hardware, run a ground cable from the alternator to the engine gr
      ound point.  I ground the engine at the starter using the same gauge wire as
       the positive lead going to the starter.  I do a short jumper from this poin
      t to ground the alternator.
      
      Remember, ever amp of juice running to the starter or from the alternator ha
      s the same current in the ground path.  
      
      If you still have a problem, try swapping out the source switch/breaker (wha
      t I assume you mean by field switch).  If you have a corroded or other high r
      esistance type you may be causing the internal voltage regulator to fail ove
      r time.  I'd place this in the long shot category but if you are on the thir
      d alternator and the ground is good, then it may be worth your time, especia
      lly if the alternators failed because of the internal voltage regulator.
      
      The real stretch would be if you did any thing to the comm or xpdr antennas o
      r antenna leads, or if you are having new problems with either.  If somehow y
      ou are inducing rf current 
      Into the alternator I could, maybe, kind of, see this causing the repeated f
      ailure.
      
      Good luck,
      Carl

      Thanks Carl & Mike.
      
      Good stuff to check out. 
      
      I'll let you know results.

      Ken,
      
      Have you checked the ground wires, especially the one from the engine case
      to the firewall?  Sometimes loose and/or dirty grounds will cause problems.

      Listers,
      
      I have put 1175 hours on my RV6 over the last 10 years and I'm currently
      having serious alternator problems. 
      
      I have Vans "steam" engine gauges including an analog ammeter and voltage
      meter. While cruising at altitude about a month ago I noticed my ammeter
      start to "quiver" a lot. After dancing back and forth from neg to positive,
      it finally went solid to the negative side. I figured I lost my alternator
      but wasn't too concerned. I turned off my strobes to save battery life and
      headed home. My battery had plenty of life for my radio and transponder. 
      
      I removed my alternator, had it checked (it was dead) and bought a new one. 
      
      After about 5 hours on the replacement, the same scenario occurred. I talked
      to others more knowledgeable than me (just about everyone) and elected to
      install another one just in case it was a bad alternator. You guessed it;
      same thing happened. BTW, before changing out the first alternator, I
      checked all electrical connections to see if I could find anything loose and
      could not. The only thing I found was the nut attaching the heavy gauge line
      from the positive battery to the master relay was snug but not tight. There
      was also a little residue on the master relay that looked like it may have
      'arced' at some time. I sinched down the nut and hoped that was my problem. 
      
      I am now on my 3rd alternator in a month. This time, I bought a "Plane
      Power" one from Vans. Yesterday, my ammeter started the boogie dance again.
      I shut off the alternator by turning off my field switch on my panel for a
      while and periodically turned it back on to charge the battery. But after it
      was on for a while, the ammeter started to quiver and dance as it has done
      before just before it failed. In all three cases, when the alternator is on,
      the battery is showing 14.5 volts. Also, all 3 alternators have internal
      voltage regulators.
      
      
      Any and all suggestions / advice is much appreciated.

      The easiest way to kill a 'one wire' alternator is to have the load drop 
      off line suddenly. That sounds like what you're describing. If the load 
      drops off, the regulator in the alternator cannot reduce the field 
      voltage quickly enough to prevent a large spike in output voltage, which 
      exceeds the ratings of the components in the regulator & it dies. If 
      there's a loose connection or flaky contact anywhere in the circuit, it 
      can look like an open circuit to the alternator.
      
      Any loss of continuity between the alternator & the load (battery and/or 
      that electrical stuff that's operating) can cause this 'load dump'. This 
      loss can be on the positive path, or the ground path.
      
      Check all connections between the alternator's output and the battery 
      (screw terminals, contacters, circuit breakers, battery posts, etc).
      
      Also check the ground return path. (This one is easy to overlook.) Don't 
      use the motor mount for your ground return from the motor to the 
      airframe; make sure you have a ground strap from the motor itself (or 
      better yet, the alternator case) to the airframe ground, and be sure 
      that the airframe has a good connection to the battery negative.
      
      FWIW,
      
      Charlie

      Ken, I had almost the same thing happen on my RV3 ... I decided to rewire
      =C2- after the 2nd alternator (internal regulators) and in the process fo
      und the heavy wire from the alternator to the ammeter/ breaker had a "hot" 
      spot in it that was brittle and barely joined by a few strands. The only th
      ing holding it together was the "skin" .=C2- It tested good continuity bu
      t was in fact not letting the full amount of electricity through and would 
      somehow burn the alternator up in short order. Replacing the wire fixed the
       problem and cured the bounce/jitter in the gauge.
      Might not be your issue but, wouldn't hurt to check.
