Bob,

 

I am planning on using the Z14 wiring for the FADEC electronic ignition.  I am going to use two Odyssey PC680 batteries to be located under the pilot/co-pilot seats.  There is plenty of room for upright installation with ample room to also install the master relays, crossover relay, and starter contactor and voltage regulators as well.  I will also have the wing leveler autopilot servo in the same area.  This is essentially dead space that is not usable for storage.

 

The question is do you see any issues with having all the relays, contactors, and voltage regulators located under the seats in the same area?  Past experience with batteries have proven keeping them inside greatly extends their life but not sure if there are other issues I  am not considering.  There is plenty of room, lots more than behind the firewall and more accessible too. 

 

 

Thanks,

 

Bob Reed

   Suggest the cross tie contactor be on the fire wall.

   "All roads used to lead to Rome", all systems lead to

   the cross-feed contactor . . . good place to tie

   alternator and bus feeders.

   Under the seats is fine as far as I can see . . .

   others may have some caveats to offer. If the

   batteries are there, then the battery busses could

   be there too since you are obviously planning for

   handy access.
