 Posted: Mon Aug 03, 2009 8:28 am Post subject: Firewall position of electrical components [RV-7A -- Z-13/8] |
 |
|
Did a search for this under the RV archive but couldn't find what I was looking for. I just got my initial order from B&C of electrical system components (i.e. "electro-whizzies"). Can someone with an RV series aircraft post or send me a picture/diagram/description of where on the firewall you located the battery, starter contactor, battery contactor and B&C grounding block? Van's firewall diagram doesn't really address this, although it looks like he intends for the battery to be mounted down low on the right side. I'm planning on mounting an IO-320 (someday) and using a Z-13/8 architecture with a swing-down fuse block panel on the passengers side of the sub-panel so this position would seem to make sense. The contactors are heavier than I expected so I'm guessing they need to be mounted on something sturdier than just the firewall skin. Any comments welcome.

Are you planning the battery on the engine side of the firewall or inside? IIRC the inside install has the contactors spec'd to be mounted on the battery box and that's on one of the fuselage drawings. For the taildragger, the Odyssey battery can be mounted on the right side with the contactors just below it. The drawing has very specific locations for the battery box and the contactors and a doubler so it ties to the firewall angles. The nose wheel location is different due to the interference of the mount but I'm sure it's equally as specific. It's on a drawing that comes with the firewall forward kit. Firewall penetration points are on a different drawing that may also be part of the FWF kit. If you didn't buy the FWF from Van's then you probably don't have the right drawing. I borrowed them from a friend but I think Van's will sell you any individual drawing for $3. Sorry but I don't have the numbers handy.
