From: J Riffel Now, I would NEVER forget to turn the master off and drain the battery down on my RV7A. I have a shutdown checklist and I even leave the strobes on so I'll know the master is on as I walk away. However this past weekend some gremlin did that to me while I was on a trip. :) The standard design doesn't allow you to jump start a RV7. The cowl must be removed to get to the battery. And putting the cowl back on while the engine is running is more than just a little tricky :) Luckily I was at an airport with a staffed FBO and a battery charger so I could solve the problem (I even carry enough tools to remove the cowl and battery). But the event got me thinking. So I'm curious how others have designed a solution to a dead battery at small airport that may have limited/no support (like places I will probably fly into). I think I have 4 options: 1) Do not design a solution (hoping the problem won't happen) 2) Put an access door over the battery for jumper cables 3) Install a "standard" external power plug 4) Fabricate a connection for the positive jumper cable (negative jumper can be attached to exhaust/other ground) Distractions happen, so option 1 isn't very good. I guess I could just carry a battery charger as part of my std tool kit and wait till the battery will crank the engine ... unless the battery won't take a charge. Option 2 is a fair amount of work and some parts cost for only occasional (hopefully) use - besides it seems to 'clutter up' the look. Option 3 could be good. But it begs the question of what "standard" connectors are probably available at a small airport (Cessna, Piper, 'universal' or auto jumper cable). Parts cost could be a little pricey and it'll "clutter up" the look. Option 4 could be good. Normal auto jumpers would work and parts cost could be low. But there are questions on how/where the terminal is mounted. The jumpers need to be disconnected safely while the engine is running and cowl is installed. It needs to be protected (somehow) against accidental shorting while working near it. And I wouldn't want to have to disconnect the terminal every time I removed the cowl. It also shouldn't clutter up things or be prone to be covered in engine oil. Any great ideas/other solutions out there? A picture would help.

From: thomas sargent I put my battery where the old old (1999) RV-6A plans say to put it - in the cabin up against the firewall. Things are too crowded under the cowl anyway. Keeps it cooler and closer to the C.G. too. I never thought about it, but it also makes the thing accessible for a jump start.

Hey Jerry, I'm building a -7 also and I'm planning on Option #3. Take a look here http://www.chiefaircraft.com/airsec/Aircraft/Tools/BatteryService.html You can place an external AN 2552-3A Oval Power Receptacle (ASOC 4621B) in a several locations of your choosing and carry a Plug and Jump (CA 311807) with you in the flight bag or on the ship somewhere. If your need a jump somewhere take out the plug and play and use regular jumper cables from anyone. Plug it in the installed receptacle, attach, jump, unplug and on your way without ever removing any part of your airplane. That's my idea anyways.

Linn > > "Jerry", RV7A, 90+ hrs ________________________________ Message 10 ____________________________________ Time: 10:57:42 AM PST US Subject: Re: RV-List: Jump Starting? From: mr.gsun@gmail.com I had the similar occurance happen a couple times with the master left on (it can happen) and running the battery low failing a successful hot start with my fuel injected engine. I've mostly solved the above two problems but came up with a good solution, I think. I have a small trickle charger that I connect occasionally to the airplane via the included black rubber clad connector that I reach and connect thru the oil filler door. It has a little ATC type fuse near the battery terminal. What I did was fabricate a jumper cable with a mating plug, 8' of 12 gauge wire and some small insulated alligator clips, color coded red/black. Then I figured I never wanted more than 10 amps going thru the jumper setup so I got a 10 amp self resetting circuit breaker that goes into the ATC fuse. It is sized to protect all the wires involved. The trickle charger only puts out a couple amps. This way, I can charge up from any airport charger, car, friends truck, lawn tractor or even the little solar panel I sometimes carry. I figure that by the time I could get the cowl off, the battery could be charged up enough to turn over the engine just by what I can get thru the jumper wire setup. Works for me....

Something like this: http://www.amazon.com/Wagan-9796-Quick-Jumper-Jumpstarter/dp/B00005OWK2 It's fairly light and small and very portable. I'm having problems finding any specifics on the current limits of this device so that the cigarette lighter circuit could be properly designed. The one downside that I see is a battery so dead that the master can't be energized, but that can be easily gotten around.

Option #4 is the simplest in my opinion. Just put a lug on the firewall side that you can access through cut out in the bottom of the cowl. Just be sure it is not close to the firewall (isolate with rubber grommets) so that you don't risk touching anything to ground. Cover with a rubber boot to keep anything from shorting out in flight. In an RV a dead battery is pain if you don't have those provisions. Ask me how I know :-)..especially when your radio stack is mounted to the battery box on an RV-4!

Now, I would NEVER forget to turn the master off and drain the battery down on my RV7A. I have a shutdown checklist and I even leave the strobes on so I'll know the master is on as I walk away. However this past weekend some gremlin did that to me while I was on a trip. :) The standard design doesn't allow you to jump start a RV7. The cowl must be removed to get to the battery. And putting the cowl back on while the engine is running is more than just a little tricky :) Luckily I was at an airport with a staffed FBO and a battery charger so I could solve the problem (I even carry enough tools to remove the cowl and battery). But the event got me thinking. So I'm curious how others have designed a solution to a dead battery at small airport that may have limited/no support (like places I will probably fly into). I think I have 4 options: 1) Do not design a solution (hoping the problem won't happen) 2) Put an access door over the battery for jumper cables 3) Install a "standard" external power plug 4) Fabricate a connection for the positive jumper cable (negative jumper can be attached to exhaust/other ground) Distractions happen, so option 1 isn't very good. I guess I could just carry a battery charger as part of my std tool kit and wait till the battery will crank the engine ... unless the battery won't take a charge. Option 2 is a fair amount of work and some parts cost for only occasional (hopefully) use - besides it seems to 'clutter up' the look. Option 3 could be good. But it begs the question of what "standard" connectors are probably available at a small airport (Cessna, Piper, 'universal' or auto jumper cable). Parts cost could be a little pricey and it'll "clutter up" the look. Option 4 could be good. Normal auto jumpers would work and parts cost could be low. But there are questions on how/where the terminal is mounted. The jumpers need to be disconnected safely while the engine is running and cowl is installed. It needs to be protected (somehow) against accidental shorting while working near it. And I wouldn't want to have to disconnect the terminal every time I removed the cowl. It also shouldn't clutter up things or be prone to be covered in engine oil. Any great ideas/other solutions out there? A picture would help.

For most of us 'lube' means grease. The important word is 'dry', and here is what they said: Keep the anchor bolts free of rust and lubricate them with a dry lubricant spray like G. E. Silicone or graphite. Don't use your old favorite WD-40, or any kind of wet grease as they will only attract dirt and compound the wear. I was taught to clean any dirt, rust etc, and reassemble dry. Never seen any pins assembled that way 'wear out' except where something else failed.

While silicone spray will work, IMHO it is inadequate to last from one annual to the next. A grease like DC-4 or other silicone grease accomplishes the same thing, with much more staying power and will reduce chance of rust. Your modern cars all use floating calipers, just like your standard Cleveland calipers, and they all specify the same silicone grease, and often supply it with replacement pads or hardware kits. If the anchor pins are dry, they will get mud from splash drying on them and that will promote both rust and wear. Spray silicone does little to protect against that. Graphite is not good around aluminum and magnesium. But, you are experimental, and you can experiment all you want. Linn Walters wrote: > > > OK, I can accept that.
